Entry structures
A freezeout gives one entry and no way back, which rewards survival and punishes early recklessness. Rebuy and re-entry events let players fire again, which builds bigger prize pools and rewards players willing to spend more than the headline buy-in.
The important number in a re-entry event is not the buy-in; it is your own predetermined maximum spend. That is the figure that decides whether the event was affordable, and it should be set before registration opens.
