to the player's temporary absence (e.g. for drinks or a restroom break) can be denoted by use of a special button. Upon the player's return, they must pay the applicable blind to the pot for the next hand they will participate in. The need for this rule is eliminated in casinos that deal in absent players as described above. Also the rule is for temporary absences only; if a player leaves the table permanently, special rules govern the assigning of blinds and button (see next subsection). In some fixed-limit and spread-limit games, especially if three blinds are used, the big blind amount may be less than the normal betting minimum. Players acting after a sub-minimum blind have the right to call the blind as it is, even though it is less than the amount they would be required to bet, or they may raise the amount needed to bring the current bet up to the normal minimum, called completing the bet. For example, a limit game with a $5 minimum bet on the first round might have blinds of $1 and $2. Players acting after the blind may either call the $2, or raise to $5. After the bet is raised to $5, the next raise must be to $10 in accordance with the normal limits. When a player in the blinds leaves the game When one or more players pays the small or big blinds for a hand, then after that hand permanently leaves the game (by "busting out" in a tournament or simply calling it a night at a public cardroom), an adjustment is required in the positioning of the blinds and the button. There are three common rule sets to determine this: Simplified: The dealer button moves to the next active player on the left, and the small and big blinds are paid by the first and second players remaining to the left. This is the easiest to track and always rotates the button, but results in "missed blinds". For instance, a player "under the gun" when the player in the big blind busts out ends up paying the small blind; they have "missed" the big blind they would have paid had the leaving player remained in the game. Similarly, a player in the small blind who busts out means the player in the big blind gets the button, missing the small blind. In the special case
