The game is played up to a certain number of points and consists of several rounds. The winner of the round is the one who gets rid of all the knuckles first. He gets a bonus of 25 points, plus the total cost of the opponent's knuckles. The winner of the game is the one who scores the agreed number of points first.
At the beginning of the round, 16 dice are dealt to the players. The remaining bones are deposited in the bazaar.
The game can be played with artificial intelligence or with an online opponent in multiplayer mode.
The players take turns walking. The one with the largest three-digit knuckle starts. If no one has a knuckle with three equal digits, the one with the highest score starts.
If the first move in the round is made with a three-digit dice, the player who makes this move will receive 10 additional points. If the first move is made with the 000 knuckle, the bonus will be 40 points.
A knuckle is placed against its other face so that each of the two digits of this face corresponds to the same digit of the neighboring knuckle. If the knuckle touches two faces or a face and a vertex, all three digits must match.
If a player does not have a suitable knuckle in his turn, he takes the knuckles from the market one at a time until he takes the one that stands on the playing field. A 5-point penalty is imposed for each piece taken from the bazaar. If there are no knuckles left in the market, but the player still has nothing to walk with, then an additional 10 points will be deducted from him. And the move goes to the opponent.
The player who gets rid of all his knuckles wins the round. He gets an additional 25 points for winning. The points of the opponent's remaining knuckles are added to his total.
If both players cannot make a move, the round ends and both players receive 10 penalty points. The player with the fewest knuckles wins this round. No additional 25 points are awarded for winning this round. The opponent's points are added to the winner, but the points of the remaining knuckles are deducted.
In the next round, the winner of the previous round goes first.
Extra points for pieces built on the playing field:
50 additional points are awarded for completing the hexagon. If a player completes two or three hexagons with one knuckle at the same time, he gets 100 and 150 additional points, respectively.
40 additional points are awarded for building the bridge.
The winner is the player who scores a certain number of points - 200, 400, 500 or 600 points at the end of the round. If a player scores this number of points in the middle of a round, the game does not stop.
