The game is based on the popular UK game show of the same name, where players compete to win a cash prize. They select a golden ball, each with a cash value, but also some that have a lower value and will reduce their winnings if chosen.
The gameplay involves using a trustworthiness meter to measure the honesty of opponents' claims about the value of their balls. The player must then decide which balls to choose from, taking into account who might be lying. The game allows for two players to compete against each other in a multiplayer mode.
