Sometimes slot machines show an impossibly large number of credits won. And I do mean impossibly large, the number of credits shown as won is way larger than the actual top jackpot on the machine. In most cases, the players didn't even line up the symbols in a winning combination for the top prize. Cases like this are simply programming errors, which the game manufacturers will investigate and fix. But, have you ever been able to take advantage of this loophole and obtain winnings?
