One Chip Rule

word type: poker slang

  1. A live poker rule that states if a player puts out a single chip (even a high valued one) into a pot after a bet, it is considered a call.


Often times in a poker game at a casino, a player cannot make change during every single hand. To make things standard across the board, a casino rule for poker was made. The rule states that if you put in a single chip after a bet without saying "raise" first, it is just considered a call. This helps the dealer interpret action in a fair way and assist the game's flow.


In middle position, Brian Roberts makes a bet to $300. On the cutoff, David Williams throws in a single $1,000 chip. Because Williams did not say "raise" before throwing the chip into the pot, his action is considered a call. Once action was folded around back to Roberts, the dealer refunds $700 to Williams and then deals the flop.
