Definition of side bet
A side bet is a "layaway". By "side bet," we mean a bet that is made outside the poker table. It can be a bet on how the tournament will go or how well we perform in the tournament. For example, you enter a tournament with 5 of your friends. You make a side bet on the "last longer". The last longer means that the player who stays in the tournament the longest will have won the bet. So for example, you could all put a €20 bet aside in a jackpot and the player who came out last in the tournament will win the jackpot.
