Chess Time Controls: Bullet, Blitz, Rapid and Classical
Chess time controls explained - bullet, blitz, rapid and classical, what 3+2 or 15+10 means, increments and delays, and how to use a chess clock.
Almost every serious chess game is played with a clock. The time control decides how much thinking time each player has - and it changes the game completely. Here is what the numbers mean and how the different speeds compare.
Reading a time control
Time controls are written as minutes + seconds:
- 3+2 means each player starts with 3 minutes, and gets 2 extra seconds after every move.
- 15+10 means 15 minutes each, plus 10 seconds per move.
- 10+0 (or just "10 minutes") means no extra time at all.
The extra time per move is called the increment. It stops games from being decided only by who can move fastest at the end.
The four speeds
| Speed | Typical controls | What it is like |
|---|---|---|
| Bullet | 1+0, 2+1 | Under 3 minutes each. Pure instinct and hand speed |
| Blitz | 3+0, 3+2, 5+0, 5+3 | Fast, but with time for short calculations |
| Rapid | 10+0, 10+5, 15+10, 25+10 | Time to think on important moves |
| Classical | 90+30, or longer | Deep calculation; how tournament chess is played |
FIDE's official rules define blitz as games where each player's time (plus 60 times the increment) is 10 minutes or less, and rapid as more than 10 but less than 60 minutes. Longer games are classical (also called "standard"). Chess websites use slightly different cut-offs, and bullet is an online category, not an official FIDE one.
Classical tournament controls
Top classical events often add time after move 40. At the 2026 World Championship, for example, each player has 120 minutes for the first 40 moves, then 30 more minutes, with a 30-second increment from move 41.
Increment and delay
There are two ways to give extra time each move:
- Increment (Fischer increment): the seconds are added to your clock after each move, even if you moved instantly. You can build up time by moving fast. This is the most common system, invented by Bobby Fischer.
- Delay: your clock waits a few seconds before it starts counting down each move. You can never gain time, only avoid losing it. Common in the United States.
Which speed should you play?
- To improve, play rapid or classical: 15+10 or longer. You need time to think, and to make mistakes you can learn from. See how to get better at chess.
- For fun, blitz is great - but games are decided by fast reactions, so they teach less.
- Bullet is mostly about speed. Enjoy it, but it will not do much for your chess understanding.
Fast games do reward one skill above all: pattern recognition. Seeing a fork or a back-rank mate instantly, without calculating, wins blitz games - and puzzles are the best way to train it. Compete gives you timed puzzle runs of 1, 3 or 5 minutes.
Using a chess clock over the board
- Press the clock with the same hand you moved with. This is a rule, not just manners.
- Finish your move before pressing. Pressing first and then moving is illegal.
- Losing on time. If your time runs out ("your flag falls"), you lose - unless your opponent has no way at all to checkmate you, in which case the game is a draw (see draws in chess).
- Touch move. In tournament games, if you deliberately touch a piece, you must move it if you can. Say "I adjust" (or "j'adoube") first if you only want to straighten it.
Armageddon
When a match must have a winner, it is sometimes decided by an Armageddon game: White gets more time, but Black wins the match with a draw. Norway Chess and the new Total Chess World Championship both use it.
