Chess Time Controls
Time limits in chess make games dynamic, prevent endless thinking, and create different stylistic challenges. The settings represent Minutes + Increment, where the increment is added to a player's remaining time immediately after completing their turn (known as a Fischer increment). Below is an overview of popular preset times:
- 1+0 (Bullet Chess Clock): 1 minute per player, no increment. Requires fast reflexes and pattern recognition. Common online as bullet practice.
- 3+2 (Chess Clock Blitz): 3 minutes per player plus 2 seconds added after each move. The standard tournament blitz format that rewards tactical precision under pressure.
- 5+0 or 5+3 (Blitz Chess Clock): 5 minutes per player, with or without increment. A highly popular casual chess clock setup for clubs, home games, and other casual games.
- 10+5 or 15+10 (Rapid Chess Clock): 10 or 15 minutes per player with a 5 or 10-second increment. Perfect balance for competitive practice, letting players execute strategic plans.
- 30+0 (Classic Chess Timer): 30 minutes per player with no increment. Ideal for serious practice games and over-the-board classical tournaments.
How to Use an Online Chess Clock
Choose a time preset or enter custom settings. Pick blitz, bullet, rapid, or input your custom time settings including any fixed number of minutes and increment seconds.
Position your device. Place your phone or tablet horizontally between the two players on the table.
Set Rotation. Ensure the top player's clock face is rotated 180 degrees by keeping the 'Rotate Top' option active so they can read the digits naturally.
Tap to Switch. Tap your clock panel to end your turn. This action ensures your clock stops, pauses your countdown, and instantly starts your opponent's timer.
Monitor Time and Moves. The built-in move counters track active turns. If your clock drops to zero, the red flag-fall status will trigger, ending the game by timeout.

Frequently Asked Questions
A chess clock is a timer comprising two adjacent clocks and buttons, used to track and limit thinking times in board games. Tapping your button stops your clock and starts your opponent's.
Yes. Simply place your phone or tablet on the table between the two players. The top player's clock rotates 180 degrees so both sides can read the numbers clearly.
This signifies a game where each player starts with 5 minutes of thinking time, and gets 3 seconds added (increment) immediately after completing each move.
Named after Bobby Fischer, this is a mechanism that automatically adds a set number of seconds to a player's remaining time immediately after they finish a move, ensuring games don't end in blind time scrambles if a player moves instantly. Note that this is different from a simple delay or increment delay where time is just delayed before counting down.
Yes. Enter any number of minutes (e.g. 5) and increment seconds (e.g. 3) in the custom fields to create your own chess clock settings.
Bullet chess involves ultra-fast games (under 3 minutes). Blitz chess is fast-paced (3 to 10 minutes, e.g., 3+2 or 5+0). Rapid chess is slower (10 to 60 minutes, e.g., 10+5 or 15+10) allowing for deeper calculations.

A chess clock and a chess timer refer to the same device — a dual-countdown timer used to limit each player's thinking time during a chess game.

This tool functions as both a chess clock and a chess game timer.
