Rule of resign

For many reasons, if you resign during the game and do not have at least 1 checker at home, you will lose backgammon. When at least 1 checker is home you will lose normally according to rules. Also please keep in mind that after the time bank is over, you will lose the game or match by default.

Gammonspace app backgammon rules

DOUBLING CUBE

When the doubling cube is visible on the board, it is active in the game. If it is not visible, the game is without the cube.

When the doubling cube is rejected, then the number of points equals the last accepted value of the doubling cube. (at first doubling, the last accepted value is 1)

MONEY GAME

JACOBY RULE

In money games with a doubling cube, the game winner receives no extra credit for gammons (2x) or backgammons (3x) unless the cube has been doubled at least once.

BEAVER & RACCOON

If the doubling cube is in the game, it is possible to redouble by using beaver and raccoon rules.

The maximum possible value of the doubling cube equals the nearest higher power of 2 (Per point/Limit). eg. 0.1 / 1 = 16.

MATCH (TOURNAMENT, SIT&GO)

It is not possible to redouble by using Beaver & Raccoon

The maximum number of points a winner can earn is equal to the number of points for a match (regardless of the points actually earned)

BYE means the score: Match Points / Match points divided by two (rounded down)

(e.g. 7/3, 13/6, etc.)

CRAWFORD RULE (implicit/absolute rule)

The Crawford Rule states that when the leader first reaches a score of 1 away (e.g., in an 9-point match, they reach 8 and the opponent has 7 or fewer points), the following game is played without a doubling cube. This one game without doubling is called the Crawford Game. After the Crawford game, the doubling cube is back in play again.

RESIGN

Resign works just like a regular game over with the difference that only two results are possible:

Normal / By default (1x) - if the losing player has borne off at least one checker OR it is a Money Game with active Jacoby rule and the “centered” doubling cube (it has not been used yet).

Backgammon (3x) - In all other cases. It means, if the losing player has not borne off any pieces or in the case of a Money game with active Jacoby rule and the “off-centered” doubling cube (already used).

TIME

We differentiate time per move and time per game. The time per move is reset to its original value after each turn, the time per game is not reset. After consuming the time per move, it is subtracted from the players' time per game.

Time per game

For Money Games, the standard Game is 90 seconds. Time for match is always 90 seconds plus additional 15 seconds per additional point (3-point match has 90 + 30).

Time per move

Slow games - 10 sec time per move

Fast games - 8 sec time per move

Speed games - 6 sec time per move


Timeout loss

If the time per game runs out, it is differentiated whether it is a Money game or a match (match, sit & go, tournament).

MATCH

The player whose time has run out has lost the match automatically. The value of points the opponent receives is equal to the remaining points per match.

E.g.: Match up to 13 points, current score 7-5, player number 1 has time out: The score is 7-13

MONEY GAME

Time out works similarly to resign:

If the time runs out, only two results are possible:

Normal / By default (1x) - if the losing player (whose time has run out) has borne off at least one checker OR it is a Money Game with active Jacoby rule and the “centered” doubling cube (it has not been used yet).

Backgammon (3x) - In all other cases. It means, if the losing player (with time out) has not borne off any pieces or in the case of a Money game with active Jacoby rule and the “off-centered” doubling cube (already used).
