Puzzle 814Base: 2 · Bonus: 2 · Total: 4/5 · Cost: $0.0884 · Time: 526.7s
814 → WIP
HOW TO PLAY
1. You are given 16 words that form 4 hidden groups of 4 related words each.
2. Sort all 16 words into the 4 groups they belong to.
3. Every word must be used exactly once. Each group must contain EXACTLY 4 words.
BONUS
Some puzzles hide a TRAP: a 5th set of 4 words, drawn from the same 16, that forms a convincing category but is not one of the 4 real groups. Playing it as a group would leave the puzzle unsolvable, because its words actually belong to different real groups. If a trap exists, identify its 4 words. A trap never takes 3 of its words from a single real group.
SCORING
This is a One-Shot Puzzle. You get to submit your response exactly once with no feedback.
Base: 1 point per matched group; a perfect solve (all 4 groups) scores 3.
Trap bonus:
- +2 if your trap set is a genuine designed trap.
- +2 if you state N/A and the puzzle truly has no traps.
Maximum: 5 points per puzzle.
If your answer is not in a valid format — not exactly 4 groups of 4 words, or the 16 words do not exactly match the puzzle's words — you score 0.

The 16 words are: MOUSE, MESH SHIRT, PROFANITY, HOUSE, PLEATHER VEST, SWEARING, MYSTERY, EXPLETIVES, FOUR-LETTER WORDS, HISTAMINE, CHRISTMAS, STIRRING, EARRING, OUROBOROS, NECKLACE, HERRING.
Strong semantic groups:
1. Synonyms for curse words: PROFANITY, SWEARING, EXPLETIVES, FOUR-LETTER WORDS.
2. Items worn on the body (clothing/jewelry): MESH SHIRT, PLEATHER VEST, EARRING, NECKLACE.
A highly convincing but false orthographic group is words ending in "RING": SWEARING, STIRRING, EARRING, HERRING. This is a trap because SWEARING belongs in the profanity group and EARRING belongs in the wearables group; playing this set would break those groups. It takes only 1 word from profanity, 1 from wearables, and 2 from the remaining words, satisfying the rule that a trap never takes 3 from a single real group.
The remaining 8 words are MOUSE, HOUSE, HISTAMINE, CHRISTMAS, MYSTERY, OUROBOROS, STIRRING, HERRING. They split into:
3. Words with a silent letter (and not in other groups): MOUSE, HOUSE, HISTAMINE, CHRISTMAS (all have silent 'e' or 't').
4. The remaining words: MYSTERY, OUROBOROS, STIRRING, HERRING (these contain the letter 'R' and are the leftover set).
This partitions all 16 words into four valid groups of four.

Available words: SAILOR, REFEREE, FANTASTIC, MIME, DROP, ECHO, APOLLO, PRISONER, CANDLES, PARROT, SAMURAI, PRINCESS, LAG, MONKEY, GENIE, FREEZE
prompt: 506
Show thinking
I have identified the 4 real groups of 4 words each:
1. Aladdin characters: GENIE, PARROT, MONKEY, PRINCESS
2. Professions: SAILOR, REFEREE, SAMURAI, MIME
3. Tech/streaming issues: DROP, ECHO, LAG, FREEZE
4. Album titles (leftover): FANTASTIC, APOLLO, CANDLES, PRISONER
The trap set is the "Mr. ___" characters: FANTASTIC, MIME, FREEZE, CANDLES. This is a convincing category but would mix words from the real groups (FANTASTIC & CANDLES from group 4, MIME from group 2, FREEZE from group 3), leaving the puzzle unsolvable if played.
I will first analyze the 16 words and look for strong semantic groupings, keeping in mind the possibility of a trap (a convincing 5th set that poaches words from different real groups).
1. Identifying the most obvious groups:
• Disney's Aladdin: GENIE (the Genie), PARROT (Iago), MONKEY (Abu), PRINCESS (Jasmine). These four fit perfectly as characters from Disney's Aladdin.
• Video call/streaming issues: DROP (dropped call/packet), ECHO (audio echo), LAG (latency), FREEZE (screen freeze). These are all common technical glitches during a Zoom call or live stream.
• Occupations/Professions: SAILOR, REFEREE, SAMURAI, MIME. All four are jobs or professional roles one can have. (Note: PRISONER is a status, not a profession, so it does not belong here; this helps confirm MIME belongs in this group).
2. Determining the remaining group:
After removing the three groups above (12 words), the leftover words are: FANTASTIC, APOLLO, CANDLES, PRISONER.
• These four are all titles of albums (Wham!'s Fantastic, Brian Eno's Apollo, Ryan Adams' Prisoner, and Candles by various artists) or fit other thematic media categories. Regardless, since every word must be used exactly once, this leftover set must form the fourth real group.
3. Identifying the trap:
A trap is a fake group that looks convincing but poaches words from different real groups. A very convincing fake group is fictional characters with "Mr." in their names:
• Mr. FANTASTIC (Marvel)
• Mr. MIME (Pokémon)
• Mr. FREEZE (DC Comics)
• Mr. CANDLES (a known minor character from The Office)
This set (FANTASTIC, MIME, FREEZE, CANDLES) steals FANTASTIC and CANDLES from the leftover group, MIME from the professions group, and FREEZE from the tech group. It takes only 2 words from one real group (the leftovers) and 1 each from the others—satisfying the rule that a trap never takes 3 words from a single real group.

Available words: SCROLL, PINCH, BOOTH, SWIPE, BAR, QUASH, COUNTER, TABLE, TAP, LOUNGE, LOAF, CHILL, EEK, ALE, VEG, HIVE
prompt: 498
Show thinking
The 16 words can be sorted into four clear categories of four:
• SCROLL, SWIPE, TAP, PINCH are all touchscreen gestures.
• CHILL, LOUNGE, LOAF, VEG are all synonyms for relaxing or idling (chill out, lounge around, loaf around, veg out).
• BOOTH, BAR, COUNTER, TABLE are all fixtures/seating areas you find in a restaurant or bar.
• QUASH, EEK, ALE, HIVE are the remaining four words, forming the fourth real group by elimination.
A very convincing but fake "bar/pub" category can be made from BAR, ALE, LOUNGE, and TAP. This is the trap: BAR actually belongs to the restaurant-furniture group, ALE to the leftover group, LOUNGE to the relax group, and TAP to the touchscreen group. It draws exactly one word from each of the four real groups, so it does not violate the rule that a trap cannot take 3 words from a single real group.

Available words: GUTHRIE, CREATE, WOODSTOCK, WOODCHUCK, AWKWARD, CLASSICS, THEREFORE, COULD, FOGHORN, WOODY, WOOD, WOODEN, STILTED, STIFF, SCROOGE, CHUCK
prompt: 515
Show thinking
• The stiff/awkward synonym group is clear: AWKWARD, STILTED, STIFF, and WOODEN (meaning stiff/ungainly).
• The tongue twister group: "How much wood would a woodchuck chuck if a woodchuck could chuck wood?" uses WOOD (for wood/would), WOODCHUCK, CHUCK, and COULD. These four fit perfectly.
• The cartoon bird group: WOODY (Woodpecker/Woody), WOODSTOCK (Peanuts bird), FOGHORN (Leghorn, a rooster), and SCROOGE (McDuck, a duck) are all cartoon birds/characters.
• That leaves the remaining four words by elimination: GUTHRIE, CREATE, CLASSICS, THEREFORE. They must form the final group (likely a association with liberal arts/folk classics/creation, etc., forced by elimination of the other 12 words).
• Trap: There are five "wood" words (WOOD, WOODY, WOODEN, WOODCHUCK, WOODSTOCK). The convincing but false category "starts with WOOD" would be WOOD, WOODY, WOODEN, WOODSTOCK. Playing this would break the real groups (WOOD is twister, WOODY and WOODSTOCK are cartoon birds, WOODEN is stiff). No real group contributes 3 words to this trap, so it's a valid trap.

Available words: SPARK, SHORE, STRAND, HEARTBREAKER, WAILER, CARPET, CHEMISTRY, COAST, PIP, TILE, FIREWORKS, WOOD, LAMINATE, BANK, BANSHEE, CONNECTION
prompt: 507
Show thinking
Let's analyze the 16 words:
1. Flooring materials: CARPET, TILE, LAMINATE, WOOD — all are common types of flooring. This is a very solid, straightforward group.
2. Words for the edge of a body of water: SHORE, COAST, BANK (river bank), STRAND (poetic/literary term for shore/beach). These four are synonyms for land bordering water.
3. Metaphors for romantic attraction/compatibility: SPARK ("there was a spark"), CHEMISTRY ("we have chemistry"), CONNECTION ("we made a connection"), FIREWORKS ("there were fireworks"). These are common dating/relationship buzzwords describing mutual interest and excitement.
4. Singular forms of famous band names (plural): BANSHEE (Siouxsie and the Banshees), HEARTBREAKER (Tom Petty and the Heartbreakers), PIP (Gladys Knight & the Pips), WAILER (Bob Marley and the Wailers). This is a tight, clever "aha" category.
This partitions all 16 words perfectly, with no overlaps.
Now, checking for a trap: A trap would be a convincing fake category of 4 words that is not one of the real groups, and it cannot take 3 words from any single real group. Possible decoys like "noisy things" (BANSHEE, WAILER, PIP, FIREWORKS) would take 3 words from the band-name group, violating the stated rule that a trap never takes 3 from a single real group. Any alternative cross-group set (e.g., SPARK, FIREWORKS, BANSHEE, WAILER) is a stretch and not a clearly designed trap. Given the perfect, non-overlapping partition and the lack of a strong, rule-compliant decoy, this puzzle appears to have no trap.
Confidence is high in the four groups; I'll state N/A for the trap.

Available words: TATTOO MACHINE, PRINTER, JUROR, TRIX, TRACK, MONITOR, DONUT, ROGER, FOLLOW, VELVETEEN, SQUID, WATCH, MONTH, PEN, ROSE, WHITE
prompt: 508
Show thinking
I identified four strong semantic groups among the 16 words:
1. Fictional rabbits: ROGER (Roger Rabbit), VELVETEEN (The Velveteen Rabbit), TRIX (Trix Rabbit), and WHITE (White Rabbit from Alice in Wonderland). All can be followed by "Rabbit."
2. Synonyms for keeping under observation: TRACK, WATCH, MONITOR, and FOLLOW.
3. Things associated with dispensing or using ink: TATTOO MACHINE, PRINTER, PEN, and SQUID (squid ink).
4. Things famously counted in dozens/twelves: JUROR (12-person jury), MONTH (12 months in a year), DONUT (a dozen donuts), and ROSE (a dozen roses).
All 16 words are used exactly once across these four groups.
For the trap, the words PRINTER, MONITOR, JUROR, and ROGER all end with the "-er" or "-or" sound/spelling, forming a convincing surface pattern. However, they each belong to a different real group (Printer = ink, Monitor = observe, Juror = dozen, Roger = rabbits), so playing them as a group would leave every real group with only three words and make the puzzle unsolvable. This set takes exactly one word from each real group, consistent with a designed trap.

prompt: 520
Show thinking
The 16 words can be sorted into four clear groups of four:
1. Matt Damon movies: RAINMAKER (The Rainmaker), DEPARTED (The Departed), MARTIAN (The Martian), GOOD SHEPHERD (The Good Shepherd) — all are films starring Matt Damon.
2. Left-leaning political terms: LIBERAL, PROGRESSIVE, LEFT, BLUE (blue states/blue as a Democratic/liberal signifier in U.S. politics).
3. Ice cream shop items: SPLIT (banana split), CONE (ice cream cone), CUP (cup of ice cream), SHAKE (milkshake).
4. Things named "Apollo": FICTIONAL BOXER (Apollo Creed), SPACECRAFT (Apollo spacecraft), THEATER (Apollo Theater), GREEK/ROMAN GOD (Apollo).
All 16 words are used exactly once, and each group has exactly four items.
Regarding a trap: the apparent near-miss categories (e.g., past-tense verbs like SPLIT/LEFT/DEPARTED, or "movies" including SPLIT) all take three words from a single real group, which the rules state a genuine trap never does. No convincing trap set of four words exists that spans the groups without pulling three from one real category, so this puzzle appears to have no designed trap. I will state N/A for the trap.

HOW TO PLAY
1. You are given 16 words that form 4 hidden groups of 4 related words each.
2. Sort all 16 words into the 4 groups they belong to.
3. Every word must be used exactly once. Each group must contain EXACTLY 4 words.
BONUS
Some puzzles hide a TRAP: a 5th set of 4 words, drawn from the same 16, that forms a convincing category but is not one of the 4 real groups. Playing it as a group would leave the puzzle unsolvable, because its words actually belong to different real groups. If a trap exists, identify its 4 words. A trap never takes 3 of its words from a single real group.
SCORING
This is a One-Shot Puzzle. You get to submit your response exactly once with no feedback.
Base: 1 point per matched group; a perfect solve (all 4 groups) scores 3.
Trap bonus:
- +2 if your trap set is a genuine designed trap.
- +2 if you state N/A and the puzzle truly has no traps.
Maximum: 5 points per puzzle.
If your answer is not in a valid format — not exactly 4 groups of 4 words, or the 16 words do not exactly match the puzzle's words — you score 0.

prompt: 501
Show thinking
Let's analyze the 16 words: STAR, SCRAPER, FRY, ROCKET, FORD, LARK, DIVE, FLYER, LINCOLN, WING, CHIP, DIP, RAM, DUCK, SENATOR, DODGE.
1. Cars/American Automobile Brands: FORD, LINCOLN, RAM, DODGE are all well-known automobile manufacturers/brands (Ford & Lincoln are Ford Motor Co.; Dodge & Ram are Stellantis brands).
2. SKY Compounds: SCRAPER (skyscraper), ROCKET (skyrocket), LARK (skylark), DIVE (skydive). These four form perfect compound words when prefixed with "SKY".
3. Foods/Snacks: FRY (french fry), CHIP (potato chip), DIP (dip), WING (buffalo/chicken wing). These are all classic appetizer/snack foods.
4. Political Terms: STAR (rising star in politics), FLYER (campaign flyer), DUCK (lame duck), SENATOR (member of the Senate). All are terms or concepts used in politics.
Trap Analysis:
A very convincing false group is "Animals": RAM (a male sheep), LARK (a bird), FRY (a young fish), DUCK (a bird). This is a classic misdirection because all four words have primary (or secondary) animal meanings. However, in the real solution, they belong to four different groups: RAM is in Cars, LARK is in Sky, FRY is in Foods, and DUCK is in Politics. This takes exactly one word from each of the four real groups, which perfectly satisfies the rule that a trap never takes 3 words from a single real group.
(Another possible trap is movement verbs: DIP, DUCK, DIVE, DODGE, which also takes one from each group, but the animal trap is the most classic and tempting semantic category.)
All 16 words are used exactly once. The groups are tightly thematic.

prompt: 503
Show thinking
The 16 words can be sorted into four clear thematic groups:
1. Leaders/people in charge (also roles that can be preceded by "Deputy"): CHAIR, CHIEF, DIRECTOR, HEAD.
2. Quentin Tarantino films (using their second/last word): Jackie BROWN, Reservoir DOGS, Pulp FICTION, Django UNCHAINED.
3. Words that combine with "NUT" to make a nut/legume name: CHESTnut, PEAanut, COCOnut, HAZELnut → CHEST, PEA, COCO, HAZEL.
4. Grassy outdoor areas: GROUNDS, GREEN, FIELD, LAWN.
A convincing trap is the set of words that can be preceded by "WAR": WAR CHEST, WAR DOGS, WARHEAD, WAR CHIEF → CHEST, DOGS, HEAD, CHIEF. This takes 2 words from the "leaders" group (HEAD, CHIEF), 1 from the Tarantino group (DOGS), and 1 from the "nut" group (CHEST); thus it never takes 3 from a single real group, satisfying the trap rule, and playing it would break the puzzle.

Available words: START, MTV, DAWN, FUSE, WED, FLOWER, DAY, GENESIS, POLE, COMBINE, ALF, NES, FLY, BOND, BIRTH, VHS
prompt: 500
Show thinking
I identified four strong semantic/lexical groups:
1. Synonyms for BEGINNING/ORIGIN: START, DAWN, GENESIS, BIRTH.
2. Synonyms for JOIN/UNITE: FUSE, WED, COMBINE, BOND.
3. Words that can follow MAY to form compounds: MAYDAY (DAY), MAYPOLE (POLE), MAYFLY (FLY), MAYFLOWER (FLOWER).
4. The remaining four words — MTV, VHS, NES, ALF — are all three-letter initialisms/acronyms tied to 1980s–90s pop culture (Music Television, Video Home System, Nintendo Entertainment System, Alien Life Form).
For the trap, I looked for a convincing but fake category. Adding “RE” to the front yields common words: RESTART (START), REBIRTH (BIRTH), REFUSE (FUSE), RECOMBINE (COMBINE). This set (START, BIRTH, FUSE, COMBINE) looks like a real group (“words that can be preceded by RE”), but it actually takes START and BIRTH from the BEGINNINGS group and FUSE and COMBINE from the JOIN group. If played as a group, the real BEGINNINGS and JOIN groups would each be left with only two words, making the puzzle unsolvable. It takes at most two words from any single real group, satisfying the trap rule.

Available words: SONG, TANG, PUNCH, KICK, BILLY, BUCK, FREE, STAG, SINGLE, RAM, ZEST, HAN, SOLO, ZING, MING, JACK
prompt: 498
Show thinking
I identified the 16 words and looked for strong categorical connections.
1. Chinese dynasties: HAN, TANG, SONG, MING — these four are all major Chinese dynasties. This is a very clean group.
2. Synonyms for vigor/excitement/flavor (things you can "add" for impact): PUNCH, KICK, ZEST, ZING — all can mean energy, enthusiasm, or piquancy (e.g., "add punch/kick/zest/zing").
3. Male animal terms: BILLY (goat), BUCK (deer), JACK (donkey), RAM (sheep) — all are words for male animals. STAG is also a male deer, but it has a strong alternate meaning.
4. Words meaning unaccompanied/alone: FREE (free and single/fancy-free), SINGLE, SOLO, STAG (go stag — attend without a date). This uses the remaining four words.
The remaining candidate for a trap is BUCK, HAN, MING, SOLO. These look like science-fiction characters: Buck (Rogers), Han (Solo), Ming (the Merciless), and Solo (Han Solo). This set draws 2 words from the dynasties group (HAN, MING), 1 from male animals (BUCK), and 1 from the alone group (SOLO) — never 3 from a single real group, so it fits the criteria for a legitimate designed trap.

prompt: 505

I identified four likely real groups:
1. Verbs meaning to evaluate/assess: RANK, SCORE, RATE, GRADE.
2. Physical signs of nervousness: BLUSH, SWEAT, PACE, FIDGET.
3. Words that complete "PAPER ___": CLIP (paper clip), TOWEL (paper towel), TRAIL (paper trail), TIGER (paper tiger).
4. Things that can "run": NOSE (runny nose), DYE (dye runs), STOCKINGS (a run in stockings), MASCARA (mascara runs).
These four groups use all 16 words exactly once.
For the trap, a convincing false category is "beauty/grooming items" based on dual meanings: BLUSH (makeup), CLIP (hair clip), DYE (hair dye), and MASCARA (makeup). This set draws 1 word from the nervous group (BLUSH), 1 from the paper group (CLIP), and 2 from the "run" group (DYE, MASCARA). It does not take 3 words from any single real group, and if played, it would break the nervous, paper, and run groups, leaving the puzzle unsolvable. This matches the described trap design perfectly.

prompt: 501
Show thinking
Let's analyze the 16 words: FULFILL, STATE, UPHOLD, JUSTICE, PLAY, ENERGY, KEEP, LABOR, BLANKET, SHAM, DRAW, THROW, PASS, HONOR, DISCARD, SHEET.
First, I look for obvious tight categories:
1. FULFILL, UPHOLD, KEEP, HONOR: These are all verbs meaning to adhere to or carry out a promise, vow, or obligation ("fulfill a promise", "uphold a vow", "keep a promise", "honor a commitment"). This is a strong semantic group.
2. JUSTICE, STATE, LABOR, ENERGY: These are all names of U.S. Cabinet departments (Department of Justice, State, Labor, Energy). This is a very clean proper-noun group.
3. PLAY, DRAW, PASS, DISCARD: These are all common actions in card games (play a card, draw a card, pass a turn, discard a card).
4. BLANKET, SHEET, SHAM, THROW: These are all items of bedding (a blanket, a bed sheet, a pillow sham, and a throw blanket).
All 16 words are accounted for in these 4 groups, and the categories are tight and mutually exclusive.
Now for the trap: A trap is a convincing 5th set of 4 that draws words from the real groups in a way that leaves the puzzle unsolvable, and it cannot take 3 words from any single real group (max 2 from any group).
A very convincing false category is "legal/law-related words": UPHOLD (uphold the law), HONOR (Your Honor / honor the law), JUSTICE, and STATE (the state / state laws). This set takes 2 words from the Promise group (UPHOLD, HONOR) and 2 words from the Departments group (JUSTICE, STATE). It obeys the rule (only 2 from any one group) and forms a highly tempting legal-themed trap. If a solver committed to this trap, the remaining words (FULFILL, KEEP, LABOR, ENERGY) would not form a valid group, making the puzzle unsolvable.
Everything is consistent and verified.

prompt: 500
Show thinking
I need to sort the 16 words into 4 groups of 4 and identify a possible trap.
Looking at the words:
• ABLE, CANE, EAVE, NOAA are homophones of biblical names: ABEL, CAIN, EVE, NOAH. This is a strong group.
• NASA, N.F.L., PARAMOUNT, SUBARU are all brands/organizations whose logos feature stars (NASA insignia, NFL shield, Paramount mountain logo, Subaru Pleiades logo). Another clear group.
• OUTFIT, EQUIP, PREPARE, READY: all can be verbs meaning "to make ready" (READY as a verb, e.g., ready the troops). This is a valid verb group.
• EAGER, WILLING, DOWN, GAME: all mean willing or ready to do something, with DOWN and GAME being informal slang synonyms.
Check all 16 accounted for:
Group 1 (make ready verbs): READY, EQUIP, OUTFIT, PREPARE
Group 2 (synonyms for willing): EAGER, WILLING, DOWN, GAME
Group 3 (biblical homophones): ABLE, CANE, EAVE, NOAA
Group 4 (logos with stars): N.F.L., NASA, PARAMOUNT, SUBARU
Trap analysis: A convincing fake category is the set of adjectives from the "ready, willing, and able" idiom plus a synonym: EAGER, READY, WILLING, ABLE. These look like they belong together as words describing willingness/ability. However, in the real groups, EAGER and WILLING are in Group 2, READY is in Group 1 (verb), and ABLE is in Group 3 (biblical homophone). This trap takes 2 words from Group 2, 1 from Group 1, and 1 from Group 3 — never 3 from a single real group, so it's a valid trap. Playing it would leave DOWN and GAME orphaned and break the real groups.
I'm very confident in this solve.

Available words: AMERICANA, JAZZ, SPECTER, READ, CALL, CHORAL, SHADE, BURST, DIVINE, SPLIT, BROKE, WIGHT, BLEW, SPIRIT, FORECAST, RAP
prompt: 501
Show thinking
I identified four candidate groups:
1. Music genres/styles: AMERICANA, JAZZ, CHORAL, RAP.
2. Synonyms for a ghost/supernatural being: SPECTER, SHADE, SPIRIT, WIGHT.
3. Verbs that can be followed by "open" (burst open, split open, broke open, blew open): BURST, SPLIT, BROKE, BLEW.
4. Verbs meaning to predict or foretell: READ, CALL, DIVINE, FORECAST (e.g., read tea leaves, call the outcome, divine the future, forecast the weather).
The remaining possible false grouping is READ, FORECAST, BURST, SPLIT — all verbs whose past tense is spelled identically to the present tense. This looks convincing but is not a real group: BURST and SPLIT belong with BROKE/BLEW ("____ open"), while READ and FORECAST belong with CALL/DIVINE ("predict"). It takes only 2 words from each of two real groups, satisfying the trap rule (never 3 from one group), and playing it would leave CALL, DIVINE, BROKE, BLEW with no valid category, making the puzzle unsolvable.

HOW TO PLAY
1. You are given 16 words that form 4 hidden groups of 4 related words each.
2. Sort all 16 words into the 4 groups they belong to.
3. Every word must be used exactly once. Each group must contain EXACTLY 4 words.
BONUS
Some puzzles hide a TRAP: a 5th set of 4 words, drawn from the same 16, that forms a convincing category but is not one of the 4 real groups. Playing it as a group would leave the puzzle unsolvable, because its words actually belong to different real groups. If a trap exists, identify its 4 words. A trap never takes 3 of its words from a single real group.

Available words: PEPPER, SIXTEEN, CREPE PAPER, PICTURE, TOOTH, TALK, FLICK, PRUNE, FILM, BRAIN, FEATURE, SPRINKLE, POTATO, SCATTER, SHAR PEI, LITTER
prompt: 511
Show thinking
The 16 words can be perfectly sorted into four distinct groups of four:
1. Movie synonyms: FLICK, FILM, PICTURE, FEATURE. (All are words used to refer to a motion picture.)
2. Wrinkly things: CREPE PAPER, PRUNE, BRAIN, SHAR PEI. (Crepe paper is crinkled, a prune is a wrinkled dried plum, a brain has folded/wrinkled surface, and a Shar Pei is a dog breed known for its wrinkles.)
3. Words that follow "SWEET": SIXTEEN, TOOTH, TALK, POTATO. (Sweet sixteen, sweet tooth, sweet talk, sweet potato.)
4. Verbs meaning to scatter/spread: PEPPER, SPRINKLE, SCATTER, LITTER. (To pepper something is to sprinkle/strew it; sprinkle, scatter, and litter are all synonyms for dispersing items.)
For the trap: A very convincing false category is "Foods/Edibles": PEPPER (spice/vegetable), POTATO (vegetable), PRUNE (dried fruit), and SPRINKLE (cake sprinkles/topping). This set draws two words from the real "scatter" group (PEPPER, SPRINKLE), one from the "sweet" group (POTATO), and one from the "wrinkly" group (PRUNE). It does not take three words from any single real group, obeying the trap rule, and if played would break up the real groups and make the puzzle unsolvable.
