Gomori

Gomori is a 2 Player Tactical-Card-Game played with a default 52-Card-Deck influenced by Connect 4, Reversi and Triple Triad.

Setup

  • The 52-Card-Deck is split into two 26-Card-Decks by color -- one deck containing the black suits (clubs (♣), and spades (♠)), the other one containing the red suits (diamonds (♦) and hearts (♥)). Each player plays their own deck.
  • The game is played on a loosely defined 4x4 field (as long as there are no 4 fields in an axis, the field can be extended in either direction).
  • Each player draws 5 cards from their deck -- the remaining cards are used as draw pile.
  • The player playing the black suits begins.
  • Gathered cards of each player are placed upside down clearly distiguishable on the respective players side of the field.

Goal

The player with the most gathered cards wins.

Rules

Gathering Cards

  • If four cards of same suit lie in one row, column or diagonal line, the player who just laid the fourth one takes the cards (including stacks) except the one laid last (including its stack) and stacks them face-down on their gathered cards stack.

Activating Face-Cards and Turning Cards Face-Down

Face Cards have each an additional effect, that gets activated when played on another card. These effects have to be executed and are executed before any other action including gathering cards.

  • The Jacks: All face-up cards lying horizontally and vertically next to the jack are turned face-down
  • The Queens: All face-up cards lying diagonally next to the queen are turned face-down
  • The Kings: One card anywhere on the field by the current players choice is turned face-down -- the king itself can also be chosen

  • Always when one cards is stacked on top of another card, the current player plays another card if possible
  • This is chained until either
    • a card is played on an empty field or
    • the player has no more cards on their hand or
    • the player has no legal move left to play another card.
  • If a line of four is completed by stacking one card on top of another, the other three cards of the line are taken before the current player plays the next card.

  • If the current player cannot fill up their hand at the end of turn for the draw pile being empty, the game ends immediately and the gathered cards are counted for each player.
  • The game also ends, if both players cannot play any card in consecutive turns.

Trivia

The name of the game comes from combining the words Go and Memory, as the first version of the game had elements of both of them. Though all these gameplay-elements have been removed from the game at later stages, the name stayed the same.
