Poker Dealer Button Rules: How the Button Moves
How the dealer button works in poker: what it marks, how it moves each hand, and the dead button and dead small blind rules when players leave.

The dealer button is the small disc that marks who is the nominal dealer for each hand. It does three jobs at once: it sets who posts the blinds, it decides the order of action, and it grants the button seat the right to act last after the flop — the single biggest positional advantage in poker. After every hand the button slides one seat clockwise, so the advantage rotates evenly among everyone at the table.
What the button controls
In a casino, a professional dealer deals every hand, yet the button still moves — because it’s tracking position, not who touches the deck. Everything the button governs:
- Blind posting. The small blind sits immediately left of the button; the big blind is one seat further left.
- First to act preflop. Action opens with the player left of the big blind.
- Last to act postflop. On the flop, turn, and river, the button acts last of all players still in the hand.
That last point is why players fight to be “on the button.” Acting last means you see what everyone else does before you decide — a permanent information edge explored further in our guide to position.
Normal rotation
In the standard case, the button’s life is simple:
| Event | What happens to the button |
|---|---|
| Hand ends | Button moves one seat clockwise |
| Small blind posted | Seat immediately left of button |
| Big blind posted | Two seats left of button |
| Player folds | No effect — button stays put until hand ends |
Over one full orbit, every player holds the button once and pays each blind once. That’s the whole point: fairness through rotation. Our how-to-deal guide covers the physical steps of setting and passing it.
When rotation breaks: players leaving
Trouble starts when the player who should receive the button next has left the table — busted out of a tournament, or picked up their chips in a cash game. If you just handed the button to the nearest remaining player, someone could end up paying the big blind twice in a row, or dodging it entirely. Two rules fix this: the dead button and the dead small blind.
The dead button rule
The dead button rule lets the button sit on an empty seat for one hand. The button still advances one position as normal, even if that position is now vacant. No one posts a blind from the empty seat — it’s “dead” — but the small and big blinds are posted correctly by the next occupied seats.
The result: the blinds keep rotating in the right order, and no active player is charged unfairly, even though the button is temporarily parked on nobody.
The dead small blind
The companion rule handles the small blind. If rotation would place the small blind on an absent player, the small blind position may go unposted for that hand, or a returning player owes it as a “dead” chip that goes to the pot without being part of their live bet. Either way, the fix guarantees:
- No player posts the big blind two hands running.
- No player skips the big blind they owe.
Worked example: a player leaves mid-orbit
Six seats, occupied 1 through 6. This hand the button is on Seat 3, so Seat 4 posts the small blind and Seat 5 the big blind. Now the player in Seat 4 leaves.
- Next hand, naive approach: move the button to Seat 4? It’s empty. Move it to Seat 5? Then Seat 5 would jump from big blind straight past the button — unfair.
- Dead-button fix: the button moves to the now-empty Seat 4 (dead — posts nothing). Seat 5, which just paid the big blind, is not forced to pay the small blind. Seat 6 posts the big blind normally.
- Result: Seat 5 gets a hand of relief after its big blind, exactly as it would have if Seat 4 were still there. Rotation stays honest.
Contrast that with a simpler “moving button” method used in some home games, which just advances the button to the next live player and accepts that the small blind is occasionally skipped. Both keep the big blind fair; the dead-button method is the casino standard because it’s the most precise.
Why it’s worth understanding
The button is the quiet engine of every hand — it decides who pays, who acts, and who holds the power seat. Most of the time it just glides one seat clockwise and you never think about it. But the moment someone leaves, the dead button and dead small blind rules keep the game fair without anyone at the table having to argue about it. Get comfortable with the normal rotation first at the Texas Hold’em table, and the edge cases will make sense.

Frequently asked
What does the dealer button do in poker?
The button marks the nominal dealer for the hand. It sets who posts the blinds, who acts first and last, and it acts last after the flop — the most powerful seat at the table. It moves one seat clockwise after each hand.
What is the dead button rule?
When the player who should be on the button leaves, the button can be placed on an empty seat for one hand so the blinds still rotate correctly. That empty button posts no blinds — it's 'dead' — but keeps the rotation fair.
What is a dead small blind?
When rotation would skip the small blind position, a player may be required to post a small blind that isn't part of a live hand for them, or the small blind is simply not posted that hand. It keeps the big blind from being paid twice by the same player.
Does the button ever skip a player?
The button itself doesn't skip active players — it moves one seat clockwise each hand. But when someone busts or leaves, casinos use the dead button and dead small blind rules so no player pays the big blind twice in a row or dodges it entirely.
