In order to designate which player is the theoretical dealer in poker games, a round disk is used. This disk is called the dealer button or simply "the button".

After each hand is completed, the button moves clockwise to the next active player and this player will be considered to be the dealer, and will act on his/her hand last on each betting round. This is also termed playing the button for that game.

As with Hold'em and Omaha games, a flat disk is used at the 5 Card Draw table, called the dealer-button to indicate the theoretical dealer of each hand.

After each hand has completed the button moves clockwise to the next active player. This player will be considered to be playing "the button" for that hand. The player to the left of the button is first to receive a card and is required to post a small blind. The small blind is equal to half the lower limit bet rounded down to the nearest dollar. The player to the left of the small blind is required to post the big blind, equal to the lower limit bet. These blind structure rules are the same as found in brick & mortar card rooms.

Both blinds are considered live bets, therefore have the option of checking, calling, raising or folding when the betting action returns to their position. After the flop and each subsequent betting round, the first active player left of the button is first to act.

When a player first sits at an active table they'll be required to post the equivalent of the big blind, an important feature of online poker. All players have the option of sitting out and waiting for the actual big blind before starting to play. Fairness is ensured to all players with these rules. By preventing players from constantly entering games in late position and leaving before they're required to post, these rules stop potential abuse of the online environment.
