A riddle that has not yet been checked by hand for accuracy and a single clean answer carries an \"unreviewed import\" label. That's an honest state, not a hidden one: the label is on every card, and none of these are run through the constraint solver the site's logic puzzles are, since a riddle's answer isn't the kind of thing that format checks.","Lateral thinking","Lateral Thinking Puzzles","Situation puzzles solved by asking yes-or-no questions — a strange scenario is presented, and exactly one hidden fact resolves it.","A lateral thinking puzzle — also called a situation puzzle — presents an odd scenario and lets you ask yes-or-no questions to work out what actually happened. Exactly one hidden fact resolves the situation; the puzzle is solvable in roughly ten good questions, no wordplay or supernatural twist required.","These are collected and curated rather than solver-verified — there's no constraint-satisfaction structure to prove a unique solution against, the way there is for the site's logic grid, zebra, and knights-&-knaves puzzles — so lateral thinking puzzles carry no ∎ badge. Each card shows whether it's reviewed or an unreviewed import.","Brain teasers","Brain Teasers","Short puzzles that reward a flash of insight rather than a long derivation — brain teasers that don't fit the site's more specific logic-puzzle categories.","Brain teasers are the catch-all for puzzles that reward a moment of insight rather than a methodical derivation — the kind where the trick, once seen, makes the rest obvious. They don't require the yes/no interrogation of a lateral-thinking puzzle or the wordplay of a riddle; they're closer to a compact \"aha\" problem.","This is a curated collection, not a solver-verified one — brain teasers don't reduce to the kind of constraint-satisfaction problem the site's logic grids, zebra puzzles, and knights-&-knaves puzzles are checked against, so they carry no ∎ badge. Each card shows whether it's a reviewed puzzle or an unreviewed import.","Math puzzles","Math Puzzles","A collection of number and arithmetic-reasoning puzzles — the answer is a number or short calculation, not a spatial arrangement.","Math puzzles here are number and arithmetic-reasoning problems — the answer comes out of a calculation or a chain of numeric logic, not a spatial arrangement like a zebra puzzle or a matching like a logic grid.","These aren't run through the constraint solver the site's logic-grid, zebra, and knights-&-knaves puzzles are — a numeric answer isn't the kind of thing that format proves unique — so they don't carry the ∎ verified badge. Some in this collection are reviewed and confirmed; others are still labeled as unreviewed imports until they've been checked by hand, and each card says which.","Knights & knaves","Knights & Knaves Puzzles","Solver-verified knights and knaves puzzles — an island where knights always tell the truth and knaves always lie. Work out who's who from what they say, with exactly one solution proven per puzzle.","Knights and knaves puzzles come from a format popularized by logician Raymond Smullyan: on this island, every islander is either a knight, who always tells the truth, or a knave, who always lies. You're given a handful of statements — often islanders talking about each other — and have to work out who's a knight and who's a knave from what's consistent.","Every knights-and-knaves puzzle here is checked by a constraint solver before it's published, which tries every possible assignment of knight/knave and confirms exactly one is consistent with every statement. The ∎ verified badge means that check ran and passed, not that we think the puzzle reads well.","Zebra puzzles","Zebra Puzzles","Solver-verified zebra puzzles in the classic Einstein's Riddle format — deduce a full row of houses, neighbors, and attributes from a list of clues with exactly one solution.","A zebra puzzle is the classic \"Einstein's Riddle\" format: a row of houses, seats, or positions, each with several attributes, and a list of clues that pin down who or what belongs where. The positional structure — first house, next to, two doors down — is what separates a zebra puzzle from a logic grid: here, order matters.","Every zebra puzzle here runs through a constraint solver before publication. It checks every possible arrangement of the row and confirms exactly one satisfies every clue — the same proof-before-publish standard the site's logic grid and knights-&-knaves puzzles carry, shown as the ∎ verified badge on each card.","Logic grids","Logic Grid Puzzles","Solver-verified logic grid puzzles: match people, items, and attributes from a list of clues. Exactly one arrangement satisfies every clue, proven before publication.","A logic grid puzzle gives you a set of clues about several people or things, each with a handful of attributes — who owns what, who did which job, who arrived when — and asks you to work out the complete matching. Unlike a zebra puzzle, there's no row or sequence to place anyone in: you're matching categories to each other, not lining anyone up.","Every logic grid puzzle here runs through a constraint solver before it's published. The solver checks every possible matching and confirms exactly one of them satisfies all the clues — the puzzle only goes live once that's proven, not assumed. That's what the ∎ verified badge on each card means.","user","pendingFriendRequests","categories",[267,268,269,270,271,272,273,274,275],{"_276":319,"_278":319,"_279":320,"_160":321,"_282":322,"_284":309,"_285":323,"_287":28},{"_276":315,"_278":315,"_279":316,"_160":317,"_282":318,"_284":309,"_285":304,"_287":28},{"_276":311,"_278":311,"_279":312,"_160":313,"_282":314,"_284":309,"_285":310,"_287":28},{"_276":305,"_278":305,"_279":306,"_160":307,"_282":308,"_284":309,"_285":310,"_287":28},{"_276":142,"_278":142,"_279":302,"_160":303,"_282":142,"_284":17,"_285":304,"_287":28},{"_276":298,"_278":298,"_279":299,"_160":300,"_282":301,"_284":17,"_285":292,"_287":28},{"_276":293,"_278":293,"_279":294,"_160":295,"_282":296,"_284":17,"_285":297,"_287":28},{"_276":288,"_278":288,"_279":289,"_160":290,"_282":291,"_284":17,"_285":292,"_287":28},{"_276":277,"_278":277,"_279":280,"_160":281,"_282":283,"_284":17,"_285":286,"_287":28},"slugEn","party","slug","name","Party games","Hidden roles and table talk for a group.","rune","mask","intent","games",3,"locale","word","Word games","Letters, riddles and words.","quill",1,"puzzle","Puzzle","Logic, numbers and patterns.","maze",5,"card","Card games","Card games for one or a whole table.","cards","Board games","Chess, xiangqi, caro and every game with a board.",8,"classics","Timeless classics","The games everyone grew up with.","crown",true,7,"five-minutes","Five-minute games","Quick rounds for a short break.","hourglass","train-your-brain","Train your brain","Puzzles, tactics and games that make you think.","mind","with-friends","Play with friends","Open a room, send the link, play together.
