Pot Limit games differ from the Limit games by the betting and raising amounts allowed:

The minimum raise amount is the previous bet or raise in the same hand. For example, if the first player bet $10, the second player can raise a minimum of $10.

The maximum raise amount is the total betting pot + total bets of other players in the betting round + the call amount of the player. For example, if the pot is $50, the first player bets $10 and the second player calls $10, the third player can raise up to $80 ($50 in the main pot + $20 from past bets in the round + $10 of the player's own call).

No Limit games differ from the Limit games in the fact that there is no maximum to each raise (apart from the player's table balance).
