ちぇいにんぐ (Cheiningu)

ちぇいにんぐ (Cheiningu) is a card game where players try to, or not to, connect two cards of the same color (Cheiningu means 'chaining').

There are 90 cards, 10 cards for each of 9 colors, in the game. The game is published in Japanese but is language free in gameplay.

Players take turns placing a card on the table to form a four-column grid. When a pair of cards of the same color are connected, orthogonally or diagonally, that player takes these cards and scores points, and the taken spaces are filled by existing cards in a certain rule. If another pair is made, that player takes them and scores again, which is called chaining. Repeat the process until no pairs are made.

There are several game modes. In one mode, you just draw a card and place it, and you should take as many cards as possible. In another mode, you choose one from your hand of two cards, and you score negative points if a single pair is made in a turn; only chainings are counted positive.

In another game, special cards may be added to change the rules slightly.

Depending on the game mode, the player with the most positive points or the least negative points wins the game.
