Off the Board Definition
If a game is taken off the board, it is no longer available to bet on even though it had been originally offered.
Bookmakers take a game off the board when they suspect the outcome of the game has been fixed, thus making sure they don’t lose any more money on that particular match.
The bookies can suspect a match has been fixed if a huge amount of money is invested on the underdog or if they obtain information suggesting that a team will intentionally lose the game.Example
A player sees a game at a bookmaker’s website and after doing some research decides to place the bet on it. However, he finds out that the game is no longer on offer and is unable to place his bet. If he had placed the bet while the game was still on the board, his bet would have been eligible for return even though the game was subsequently taken off the board.
