Calling the clock
Calling the clock lets a player ask tournament staff to limit an opponent's time to decide after an unusually long delay. Under the current TDA rules, an approved clock gives the player up to 25 seconds, followed by a five-second countdown. If time expires, the hand is dead if the player is facing a bet; otherwise, the hand is checked.
In poker, calling the clock means asking tournament staff to put another player on a time limit after they take an unusually long time to decide. It mainly prevents excessive tanking and keeps the game moving at a reasonable pace.
The procedure is most common in live poker tournaments, where players may not have a built-in countdown for every decision. Calling the clock does not mean the requesting player can start a timer themselves. The tournament director or floor staff must approve the request.
The Official Procedure for Calling the Clock
The exact procedure can vary between poker rooms and tournament series, but the TDA rules provide a widely used framework for tournament play.
Step 1: The Initial Request
A player in the tournament can request a clock when another player takes too long, as long as the requesting player is at their seat.
There is no universal rule requiring players to wait exactly two or three minutes. The TDA standard is based on whether a reasonable amount of time has passed. A difficult decision in a large pot may justify more time than a routine pre-flop decision.
Step 2: The Tournament Director Approves the Clock
The dealer can notify the floor that a player has requested a clock, but the tournament director decides whether to approve it. The TD can also call the clock without a player requesting it.
This is an important part of the poker clock rule: calling the clock is not an automatic right to put another player on a countdown whenever you become impatient.
Step 3: The Countdown Begins
Under the current 2026 TDA rules, a player on the clock has up to 25 seconds to act, followed by a five-second countdown. Tournament directors may adjust the amount of time when appropriate for the game or event.
If the player acts before the countdown expires, the hand continues normally.
If time runs out:
Facing a bet: the player's hand is dead.
Not facing a bet: the hand is checked.
If there is a tie at the end of the countdown: the ruling goes to the player.
When to Call the Clock
Knowing when to call the clock is part of good poker etiquette. The clock is meant to address excessive delays, not to rush every player who takes longer than you would.
Consider a few things before making the request:
How long has the player been thinking? A few extra seconds is very different from a prolonged tank.
How difficult is the decision? A major river decision can reasonably take longer.
Is the player regularly taking excessive time? Repeated delays can justify a clock request.
Is the slow play affecting the table? In a tournament, unnecessary delays can affect the pace of the entire event.
No fixed amount of time automatically means a clock should be called. The tournament director makes the final decision based on the circumstances.
Calling the Clock vs. a Shot Clock
Calling the clock in poker is not the same as using a shot clock.
With a traditional clock request, a player has already spent significant time thinking, and another player or the TD asks for a countdown.
A shot clock is built into the tournament structure. Players receive a fixed amount of time to act on their decisions, so they usually don't need another player to call the clock.
Feature | Calling the Clock | Shot Clock |
|---|---|---|
When it starts | After a reasonable amount of time has passed | Automatically during the hand |
Who triggers it | Player request or TD | Tournament procedure |
Main purpose | Address excessive delays | Control decision time throughout the event |
Common setting | Live tournaments without a shot clock | Modern timed tournaments |
Tournament and Cash Game Rules
The TDA poker clock rule is designed specifically for tournament play. Cash games can have different procedures because individual poker rooms govern them through their house rules.
Feature | Tournament Poker | Cash Games |
|---|---|---|
Authority | Tournament director/floor | Poker room staff |
Clock procedure | Usually defined by event rules | Depends on house rules |
Calling the clock | Recognized tournament procedure | Varies by room |
Main concern | Keeping the tournament moving | Maintaining a reasonable pace |
A player should therefore check the rules of the specific poker room instead of assuming that a tournament procedure automatically applies to a cash game.
Is Calling the Clock Bad Poker Etiquette?
Calling the clock is not automatically poor poker etiquette. The TDA rules themselves list calling for a clock when warranted among player responsibilities. The main issue is timing.
Calling immediately after an opponent faces a difficult decision can seem like unnecessary pressure. Waiting until a player has clearly taken an excessive amount of time generally aligns more with normal tournament procedure.
This is especially relevant when learning when to call the clock. The purpose is to protect the pace of the game, not to punish someone for thinking through an important hand.
What Is Slow Play in Poker?
In poker strategy, slow playing means playing a strong hand deceptively to hide its strength. In the context of calling the clock, however, the issue is excessive tanking or taking too long to make a decision.
Taking time to think about a difficult hand is normal. The problem is repeated or excessive delay, particularly when a player takes a long time over relatively routine decisions.
What Happens When the Clock Expires?
The outcome depends on whether the player is facing a bet.
For example, if a player is facing a river bet and their time expires before they act, their hand is dead. If they face no bet and fail to act before the countdown ends, the hand is checked under the TDA procedure.
This distinction is important because an expired clock does not automatically mean the same result in every situation.
| Pros | Cons |
|---|---|
Keeps the game moving: Helps prevent excessive tanking from slowing down the entire table. | Can put pressure on an opponent: A countdown may make a difficult decision more stressful. |
Sets a clear time limit: Gives the player a defined period to make a decision once the clock is approved. | May be premature: Calling the clock too quickly can be poor poker etiquette, particularly when a player faces a complex decision. |
Supports fair play: Helps tournament staff manage repeated or unreasonable delays. | Can create tension: Frequent or unnecessary requests may cause friction between players. |
