JOKSY is based on the casual card game SKYJO, which is itself based on the public-domain card game Golf.

The game is currently suited for 4 players, with AI players available for solo play.

RULES

 Players begin each round with a 4x3 grid of face-down cards, with values between -2 and 12.

After each player selects and reveals two cards, players take turns drawing and playing cards to their board, with the goal of having the lowest sum of card values.

Players may draw from the discard pile and replace a card on their board with the new card, or they may draw from the deck and choose to either play the new card, or discard it and flip a face-down card on their board.

Whenever a column has three-of-a-kind showing, the column is discarded and no longer counted towards the total points.

Play continues until a player reveals their entire board, after which every other player gets one more turn.

If the player who finishes the round does NOT have the lowest round score, their earned points are doubled for that round.

Rounds continue until one player reaches 100 points, and the winner is whomever has the lowest total score.
