====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 of three players in a tournament being reduced to the two-player showdown, any leftover blinds from other rules are "written off" and the Simplified method is used, with the player "on the button" paying the small blind.
* '''Moving button''': As in Simplified, the button moves to the left to the next active player, and the blinds move to the next two active players. However, any "missed blinds" are paid by the player whom they skipped as if they were due for the upcoming hand, with one blind paid per player, per hand, biggest blind first. Any blind a player misses on a given hand because a bigger blind was due will be paid by the player in the following hand. This is the most complex ruleset to implement, especially if multiple players leave,  but it is the fairest method overall in terms of paying all due blinds and rotating last action.
* '''Dead button''': Spots vacated by leaving players who would pay the small blind or get the button during the next hand remain open for the purposes of shifting blinds and button. Thus, the small blind may not be paid in the subsequent hand if the player due to pay the small blind has vacated the spot and, therefore, is considered "dead". However, there is always a big blind even if the spot is vacated by the player who is due to pay the big blind; in such case, the player seated to the left of the vacated spot pays the big blind.  When the dealer button moves to an empty seat, it also is considered "dead", and the last active player before the empty seat retains the "privilege of last action" by default. While simple in tournament formats and the most equitable in terms of paying blinds as due and when normally expected, it can result in inequitable strategic situations regarding last action, and becomes harder to track if the table is "open" (players can come and go) as in a casino.

In tournaments, the ''dead button'' and ''moving button'' rules are common (replacement players are generally not a part of tournaments). Online cash games generally use the ''simplified moving button'' as other methods are more difficult to codify and can be abused by players constantly entering and leaving.

Casino card rooms where players can come and go can use any of the three rulesets, though ''moving button'' is most common. When a player immediately takes the place of a player who leaves, the player may have the option to either pay the blinds in the leaving player's stead, in which case play continues as if the player never left, or to "sit out" until the button has moved past them, and thus the chair is effectively empty for purposes of the blinds. Many card rooms do not allow new players to sit out as it is highly advantageous for the new player, both to watch one or more hands without obligation to play, and to enter the game in a very "late" position (on their first hand they see all other player's actions except the dealer's). For these reasons, new players must often post a "live" big blind to enter regardless of their position at the table.
