List of games with concealed rules
Games with concealed rules are games where the rules are intentionally concealed from new players, either because their discovery is part of the game itself, or because the game is a hoax and the rules do not exist. In fiction, the counterpart of the first category are games that supposedly do have a rule set, but that rule set is not disclosed.
- Eleusis: A card game in which one player secretly decides on a rule which determines which cards may be played on top of each other. The other players then use deductive logic to work out the secret rule.
- Gestalt Number Theory: A game in which one or more objects are positioned so as to represent various numbers between zero and ten (or possibly eleven). Other players attempt to deduce the number system and can correctly state the number indicated by a given object.
- Inspector: A pseudo-hoax game in which the principal player believes they are playing a game with one set of rules, whereas in fact a separate rule applies. A new player who does not know the rules is elected as 'inspector', who is told they will be asked presented with a crime scene, and that they must deduce the crime by asking yes/no questions to the other players. The inspector is then asked to leave the room while the other players construct the crime narrative. Once the inspector has left, the other players will agree to follow the following rules: All questions ending in a consonant are answered 'no', all questions ending in a vowel are answered 'yes', and all questions ending with a y are answered 'maybe'. The inspector will be allowed to ask questions until he deduces the pattern, gives up or breaks character.
- Mao: A shedding-type card game where the winner of a round adds a concealed rule of their choice to all subsequent rounds.
- Paranoia: A tabletop role-playing game in which the rules are considered "classified" demonstrating knowledge of the rules is considered treasonous. Only the dungeon master has full knowledge of the rules, while other players must deduce them by trial and error as they proceed through the game.
- Penultima: A chess variant where the spectators make secret rules governing how the pieces move and capture. The two players are unaware of the rules and must discover them by inductive reasoning.
- Scissors: A party game in which a pair of scissors is passed between each player with the passer declaring that they are being passed "open" or "closed" based on an individual and secret rule. The other playes must use observation to deduce the rule each player uses to make their declaration.
- Whose Triangle Is It?: A party game in which one player points to three people or objects, forming an imaginary triangle, and then asks "Whose triangle is it?" The triangle belongs to whichever player is first to talk after the question, but this rule is not told to new players, and the "game" is for new players to figure out what the rule is.
- Snaps: Another party game in which one player thinks of a word and the goal is for the other players to guess it. A hint for each letter of the word is given in turn. If the letter is a consonant, then that consonant is the first letter of the first word of a sentence the player recites. If the letter is a vowel, then the vowel is expressed as a series of snaps: 1 for A, 2 for E, 3 for I, 4 for O, 5 for U.
Hoax or joke games
- 52 Pickup: A card game in which dealer scatters the cards on the floor and non-dealer must pick them up.
- Mornington Crescent: Originally a round in the BBC Radio 4 comedy panel game I'm Sorry I Haven't A Clue. The game consists of each panelist in turn announcing a landmark or street, most often a tube station on the London Underground system. The apparent aim is to be the first to announce "Mornington Crescent", a station on the Northern Line. Despite appearances, however, there are no rules to the game, and both the naming of stations and the specification of "rules" are based on stream-of-consciousness association and improvisation. Thus the game is intentionally incomprehensible.

If this leaves a player with no cards, they cannot fold and must sit in place until they lose. There are no raises and no bluffing, everyone bets, then reveals their cards, and whatever cards Howard was holding turned out to be a "Pai Tai" and won. Jerry then deals and announces a game of "Klotski", or Polish poker, for which every player needs a banana.
