Thirteen contestants, often celebrities, are selected to play in each season. Each episode (besides the season finale) features a Main Match and a Death Match. In the Main Match, all players compete to win a "token of life", which guarantees them safety from elimination that episode. What determines the winners and losers of each Main Match depends from match to match, but typically, if a single player wins the Main Match, they earn one token of life for themselves and another to give away to a player of their choice. Some Main Matches allow for more than one winner, in which case each of the winners receives one token of life. The loser of the Main Match (as determined by that match's rules) is the "elimination candidate" and is automatically sent to the Death Match. The elimination candidate selects a player without a token of life to compete against in the Death Match. If multiple players lost the Main Match, the winner(s) of the Main Match select the elimination candidate from among the losers. The Death Match is a one-on-one challenge, and the loser is eliminated from the season. Once two players remain, they compete in the best-of-three Final Match, and the first player to win two challenges is declared the winner of the season. Each season also features "garnets", which function as the show's
in-game currency, and can be used to purchase advantages during certain matches or given to other players to persuade them to make certain decisions. Every player begins the season with one garnet each, and can earn more garnets by winning Main Matches. In seasons
one and
two, the winner of a Death Match earned the losing player's garnets; in seasons
three and
four, the loser's garnets were removed from the game instead. At the end of the season, the winner's garnets are converted into cash, which each garnet worth
