Tournaments
Rebuy in poker
Definition
Buying more chips in a tournament, in the rebuy period, after you lose chips or all of them.
In a rebuy tournament you can rebuy during the first levels, either when you are out of chips or when you are below the starting stack, depending on the rules. Each rebuy adds money to the prize pool.
Rebuy tournaments reward players with larger bankrolls, because each extra chip stack costs another buy-in.
