Buy-in

In poker, a buy-in is the amount of money a player pays to join a game or tournament and receive their initial chips. The specific meaning and rules differ slightly between cash games and tournaments. 

• In cash games: buy-in = initial chip stack. 
• In tournaments: buy-in + fee contribute to prize pools and operator revenue. 

Some formats include rebuys, re-entries, or add-ons.
