A rebuy tournament in poker is a format that allows players to purchase more chips if they get eliminated or fall below their starting chip stack.
The rebuy period lasts for a predetermined amount of time, after which players who bust can’t rebuy anymore. Sometimes, players aren’t limited in terms of how many rebuys they can make within this period and can even make a double rebuy to double their starting chip stack.
Rebuy Poker Example:
Let’s say you started a poker tournament with 5,000 chips. After several poor outcomes, you lose your entire stack, so you decide to rebuy by purchasing 5,000 chips. You can do so for the price of the original rebuy and won’t have to pay the rake when doing so.
