Remove jokers. Deal each player 4 cards - 2 face-down and 2 face-up.
On a player's turn they will normally play a card to a central pile using any one of their 4 cards, draw a card to replace the one they just used, then announce the sum of the cards in the central pile. Aces and faces are worth 1.
The sum may not exceed 25. You may not play a card that would bring the sum above 25. If neither of a player's face-up cards are valid plays, they have the option of discarding any one of their cards and replacing it with a newly drawn card.
If, after a player's turn, the value of the central pile reaches exactly 25, they sweep aside the pile - scoring one point - and the next player plays the next move, starting a new pile.
The first player to score 3 points has won the game.
