Puzzle 817Base: 2 · Bonus: 2 · Total: 4/5 · Cost: $0.0143 · Time: 31.2s
817 → 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.

prompt: 682
Show thinking
The 16 words divide cleanly into four mutually exclusive groups of four.
• HAN, MING, SONG, TANG are the four major Chinese imperial dynasties that followed one another.
• BILLY, BUCK, RAM, STAG are the conventional English names for the adult males of goat, deer/antelope, sheep and deer respectively.
• KICK, PUNCH, ZEST, ZING are interchangeable informal nouns for piquancy, vitality or “oomph.”
• The remaining quartet FREE, JACK, SINGLE, SOLO therefore constitutes the fourth designed group (all can function as adjectives or nouns denoting “unaccompanied / one-only”).
No alternative grouping of four words satisfies the “trap never takes three members from one genuine group” constraint, so the puzzle contains no trap.

prompt: 693
Show thinking
The words form four clear categories after testing alternatives (including musician names, starting letters, and wood-themed items). One group is synonyms for unnatural or forced (in speech, movement, or acting). A second is well-known cartoon characters (all animals). A third collects the key content words from the classic tongue twister “How much wood would a woodchuck chuck if a woodchuck could chuck wood?” The remaining four words must form the fourth group. The most tempting false group is the set of words beginning with the string WOOD; it draws at most two members from any genuine group and would leave the puzzle unsolvable.

prompt: 692
Show thinking
The 16 words form four clean groups of related terms, with one strong red-herring set that overlaps two words from one real group and one each from two others.
• Aladdin characters (Genie, Jasmine the Princess, Abu the Monkey, Iago the Parrot) is a classic pop-culture set.
• Figures classically depicted in black-and-white horizontal stripes (mime, referee, old-style prisoner, sailor) is a visual/occupational set frequently used in connection puzzles.
• Common real-time communication or gameplay artifacts (packet/call drop, lag, screen freeze, audio echo) form a tight technical category.
• The remaining four words must therefore constitute the fourth group.
The convincing but incorrect set “things that imitate/copy” (mime, echo, parrot, monkey) draws exactly two members from the Aladdin group and one each from the stripe and technical groups, satisfying the trap constraints and leaving the puzzle unsolvable if selected.

prompt: 685

The words form these four exact groups of related terms:
• DOWN/EAGER/GAME/WILLING are interchangeable informal synonyms meaning “enthusiastic / I’m in.”
• EQUIP/OUTFIT/PREPARE/READY are interchangeable verbs meaning “to make ready or furnish.”
• ABLE/CANE/EAVE/NOAA are homophones of the biblical names Abel, Cain, Eve and Noah.
• NASA/N.F.L./PARAMOUNT/SUBARU are organizations whose well-known logos all incorporate stars.
A tempting alternative set ABLE/EAGER/READY/WILLING looks like a coherent “keen/prepared” category but mixes three different true groups and would leave the puzzle unsolvable; it therefore functions as the designed trap.

prompt: 702
Show thinking
The 16 words form four exact groups of four. First, PROFANITY / FOUR-LETTER WORDS / EXPLETIVES / SWEARING are straightforward synonyms for curse words. Second, CHRISTMAS / HOUSE / STIRRING / MOUSE are the four content words that appear together in the opening couplet of the poem “A Visit from St. Nicholas.” That leaves MESH SHIRT / PLEATHER VEST / EARRING / NECKLACE, which form a coherent set of alternative/club-fashion garments and accessories, and the remaining quartet HERRING / MYSTERY / OUROBOROS / HISTAMINE. A tempting but incorrect grouping is the four words that end in “-RING” (HERRING, EARRING, STIRRING, SWEARING); it mixes one word from the curse-word group with three words that actually belong to three different genuine groups and is therefore the designed trap.

The remaining four words must therefore constitute the fourth group (ALE, EEK, HIVE, QUASH).
A plausible but incorrect overlapping set is the expanded “places to sit/eat” collection that swaps TABLE for LOUNGE; selecting it would leave the puzzle unsolvable, so it is the designed trap.

Show thinking
The 16 words form four clear categories of exactly four items each.
Ghost/spirit synonyms: SHADE, SPECTER, SPIRIT, WIGHT are all established terms for a ghost or apparition.
Music genres/styles: AMERICANA, CHORAL, JAZZ, RAP are all recognized categories of music.
Methods of prediction or divination: CALL, DIVINE, FORECAST, READ (as in “call the election,” “divine the future,” “weather forecast,” “read the cards/palms”).
Words describing sudden rupture or failure (especially of a container, pipe, tire, etc.): BLEW, BROKE, BURST, SPLIT.
These four groups use every word exactly once and leave no remainder. No equally convincing alternative grouping of four words drawn from different real groups appears, so no designed trap is present.

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 form four clear categories of exactly four each.
• Positions of leadership or authority: CHAIR, CHIEF, DIRECTOR, HEAD.
• Open grassy areas: FIELD, GREEN, GROUNDS, LAWN.
• Types of nuts (peanut, coconut, chestnut, hazelnut): CHEST, COCO, HAZEL, PEA.
• Quentin Tarantino films (Jackie Brown, Reservoir Dogs, Pulp Fiction, Django Unchained): BROWN, DOGS, FICTION, UNCHAINED.
These groupings use every word once and leave no leftovers. A plausible but incorrect overlapping set (for example mixed color/eye-color terms) would strand words that cannot form valid remaining groups, confirming the four categories above are the intended solution. No designed trap of four words drawn from different genuine groups is evident.

Flooring materials form a clear group: CARPET, LAMINATE, TILE, WOOD.
Shore/beach synonyms form another: BANK, COAST, SHORE, STRAND (strand is a recognized term for shoreline).
Romantic “spark” metaphors form a third: CHEMISTRY, CONNECTION, FIREWORKS, SPARK.
The remaining four words (BANSHEE, HEARTBREAKER, PIP, WAILER) must constitute the fourth group; they share the sense of vivid nicknames or epithets for intense/emotional figures.
No equally plausible 4-word subset crosses the real groups in a way that would constitute a designed 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.

Available words: MERIDA, ANGULAR, TIANA, LINEAR, ARIEL, VERDANA, AREAL, SPLIT, ROUNDOFF, AERIAL, ARABESQUE, IMPACT, AURORA, ARIAL, GEORGIA, VOLUMETRIC

Show thinking
Disney princesses form a clear group: MERIDA, TIANA, ARIEL, AURORA.
Typefaces form another: ARIAL, VERDANA, GEORGIA, IMPACT.
Gymnastics/acrobatic elements form a third: SPLIT, ROUNDOFF, AERIAL, ARABESQUE.
The remaining four (ANGULAR, LINEAR, AREAL, VOLUMETRIC) are standard categories of geometric measure (angular, linear, areal, volumetric).
A plausible trap is the four near-homographs AERIAL / ARIAL / AREAL / ARIEL, which draw one word from each genuine group and would leave the puzzle unsolvable.

Available words: DISCARD, STATE, BLANKET, JUSTICE, KEEP, SHAM, PLAY, UPHOLD, ENERGY, THROW, PASS, FULFILL, SHEET, DRAW, HONOR, LABOR
prompt: 681
Show thinking
The 16 words form four clear categories of four.
Bedding items: BLANKET, SHEET, SHAM and THROW (a decorative blanket).
U.S. Cabinet departments: ENERGY, JUSTICE, LABOR and STATE.
Verbs meaning “carry out a commitment/promise”: FULFILL, HONOR, KEEP and UPHOLD.
Standard card-game actions: DISCARD, DRAW, PASS and PLAY.
A plausible but incorrect fifth grouping is DRAW/PASS/PLAY/THROW (generic “game actions”), which mixes the card set with the bedding set and would leave the puzzle unsolvable.
