A poker shot clock game works like in any other game with a shot clock feature. This is a physical clock that sits on the table and counts down the time every player has to make their decision.
If the player doesn’t call, bet, fold, or raise before the shot clock runs out, the player’s poker hand is dead.
In many poker tournaments, the shot clock feature is also accompanied by several “time bank cards.” Players can exchange these bank cards for a set amount of time so that they can think through their decision a bit more.
For instance, each player in the tournament gets thirty seconds to decide what they want to do in each betting round. If the shot clock runs out, they can put in a bank card or two to get thirty or sixty seconds more and make a better decision.
