Top > FAQ


How are the numbers on the dice decided at the beginning of the game?
The rolled values are completely random throughout the game. The numbers of dice never come out the same at the beginning of the game, as the server will automatically reroll in that case.
Why does it takes so long to find an opponent?
Players are matched within seconds, however, in case of no-good internet connection, it may take you a while to start the game.
How come the opponent reacts so slowly at times while playing?
Either the opponent is considering his/her next move or has a poor internet connection.
Why does the game suddenly stop while playing?
It is either that the opponent resigned or the internet got cut off.
Why did I win the game with Backgammon but only receive money worth x1?
BackgammonAce applies JacobyRule, in which either you or the opponent must Double the game in order to win the game with Backgammon.
What happens to the scores if one of the players resigns or the game suddenly disconnects?
AI will make a fair decision at the moment the game stopped and will calculate the appropriate scores accordingly.
It's not fair that the opponent is always getting better numbers on the dice.
The dice are never set in a particular orientation or controlled by the system and therefore are rolled randomly throughout the game. You can check your the spots of the dice on MyPage Record.

How is the amount of Chips to bet calculated?
You will bet 1/16 of the less amount of Chips possessed by one of the players. If the amount is less than 500 Chips, you will bet all 500 Chips. 
Why does a player run out of time but then recover time?
If it looks like your opponent has recovered time, it is due to the adjustment after connection delay caused, not due to cheating.
Why did I suddenly lose so much Chips?
If you lose Backgammon in a doubled game, you may lose maximum of 6 times (2 x 3) the usual amount of Chips. In addition, please keep in mind that if you resign, you could lose the highest score possible.
