Chess time controls explained: bullet, blitz, rapid, and classical

Every chess game starts with a number like 3+2 or G/30 d5. That number decides how fast you have to think, which rating the game counts toward, and sometimes whether the game is even called blitz or rapid. Here is how the categories actually work.

What is a chess time control?

A time control is the rule for how much thinking time each player gets and how that time is topped up during the game. It can have three parts: a base time per player, an optional per-move bonus in the form of an increment or a delay, and, in longer games, extra time that arrives after a set number of moves. When your time runs out, your flag falls and you normally lose on time — with an important exception for positions where your opponent could never checkmate, covered in our guide on how to use a chess clock.

The four names you hear most — bullet, blitz, rapid, and classical — are speed bands. They matter for two reasons. Ratings are usually tracked separately for each band, so a game's category decides which number moves. And the chess itself changes: a position you would calculate for ten minutes in a classical game gets a few seconds of pattern recognition in bullet.

What are bullet, blitz, rapid, and classical?

Two details hide in that table. First, bullet has no FIDE definition. It comes from online play, where Chess.com describes it as anything faster than three minutes per player. Second, the bottom edge of blitz depends on who is counting. FIDE's blitz is simply 10 minutes or less, because FIDE has no bullet band beneath it. Chess.com describes blitz as between three and ten minutes, because bullet takes everything faster.

How does FIDE count the increment?

FIDE does not look at the base time alone. Under the Laws of Chess, a game is blitz when each player has 10 minutes or less for all moves, or when the allotted time plus 60 times any increment comes to 10 minutes or less. Rapid uses the same arithmetic with a range of more than 10 but less than 60 minutes. In effect, FIDE imagines a 60-move game and adds the increment 60 times.

The same logic appears in US Chess's guidance for FIDE-rated events, which describes G/90;+30 as 120 minutes per player: 90 minutes plus 30 seconds for each of 60 moves.

Why is the same game blitz on one site and rapid on another?

Online platforms use their own formulas. Lichess, for example, estimates a game's duration as the initial clock time in seconds plus 40 times the increment, then sorts the result into bands: up to 179 seconds is bullet, up to 479 is blitz, up to 1,499 is rapid, and 1,500 or more is classical. Because Lichess assumes 40 moves instead of FIDE's 60, and because its bands break at different points, a few familiar controls land differently:

• 10+0 is 600 seconds — rapid on Lichess, but blitz under FIDE's "10 minutes or less."
• 8+0 is 480 seconds — one second past the Lichess blitz band, so rapid there, while FIDE would still call it blitz.
• 2+1 is 120 + 40 = 160 seconds on Lichess — bullet.
• 5+3 is 300 + 120 = 420 seconds — blitz on Lichess and blitz under FIDE.

None of these is wrong. They are different rulebooks answering slightly different questions. For a club game or tournament, the organizer's announced control and rating category are the ones that count.

How do you read 3+2, 15|10, and G/30 d5?

The same idea gets written three ways, depending on where you play:

• 3+2 — 3 minutes per player, with 2 seconds added after each move. Lichess, for example, writes controls this way.
• 15|10 — the vertical-bar style: 15 minutes per player with a 10-second increment. It means exactly the same as 15+10.
• G/30 d5 — US tournament style. "G/30" means game in 30 minutes per player; "d5" means a 5-second delay. In this style a delay is written with a d and an increment with a +.

The letter matters. A delay protects the first few seconds of each move but never adds time, while an increment adds seconds you can bank. Our increment vs delay guide works through both with a stopwatch's worth of arithmetic.

What does a classical control look like?

Long games often use stages. A widely used classical format gives each player 90 minutes for the first 40 moves, then 30 more minutes for the rest of the game, with 30 seconds added per move from move one.

The classical boundary is also moving. On January 12, 2026, FIDE announced that major or traditional tournaments approved by its Qualification Commission may be rated as standard at 45+30 or 60+30, with conditions such as a limit of two rounds per day. FIDE's stated aim was letting strong open events finish in five or six days instead of nine or ten.

Which time control should you play?

There is no single right answer, but the trade-offs are predictable:

• To improve your calculation, slower is better. Rapid and classical give you time to check a line twice, and to learn from the game afterward.
• For a club evening, rapid fits several rounds. At 15+10, a 60-move game uses at most 25 minutes per player by FIDE's arithmetic — about 50 minutes of clock time for the pair.
• For a quick warm-up, blitz is hard to beat. On a physical board, add an increment: 3+2 or 5+3 is kinder to the pieces than 5+0 when both flags are hanging.
• For bullet over the board, expect knocked-over pieces and disputed presses. Save it for friends who laugh about both.

Whatever you pick, agree on it — including whether there is an increment or a delay — before the first move. Changing the deal mid-game is how friendly games stop being friendly.
