It is usually written as two numbers, like **3+2**: the first is the starting time in **minutes** per player, and the second is the **increment in seconds** added after each move. So 3+2 means each player starts with 3 minutes and gains 2 seconds every time they move.\n\nThe categories are defined by how much time each player has. Under the FIDE Laws of Chess, **blitz** is 10 minutes or less per player, **rapid** is more than 10 but less than 60 minutes, and anything 60 minutes or more is standard (often called **classical**). **Bullet** is an informal term, usually for games under 3 minutes per player.\n\nIf you need a clock for a game right now, the [ClockAura chess clock](/chess-clock) runs in any browser.\n\n## The quick answer\n\n| Category | Time per player (typical) | Example controls |\n|---|---|---|\n| Bullet (informal) | Under 3 minutes | 1+0, 2+1 |\n| Blitz | 10 minutes or less | 3+0, 3+2, 5+0, 5+3 |\n| Rapid | More than 10, less than 60 minutes | 10+5, 15+10, 25+10 |\n| Classical / standard | 60 minutes or more | 90+30, 120+0 |\n\n## How FIDE counts increments\n\nThere is a detail many casual players miss. When an increment is used, FIDE counts the time control by adding **60 times the increment** to the base time. The idea is that a typical game lasts around 60 moves.\n\nFor example:\n\n- **3+2**: 3 minutes + (60 x 2 seconds = 2 minutes) = 5 minutes. Blitz.\n- **10+5**: 10 minutes + (60 x 5 seconds = 5 minutes) = 15 minutes. Rapid.\n- **15+10**: 15 minutes + (60 x 10 seconds = 10 minutes) = 25 minutes. Rapid.\n- **45+15**: 45 minutes + (60 x 15 seconds = 15 minutes) = 60 minutes. Standard, not rapid.\n\nThat last one surprises people. Online platforms sometimes use their own category boundaries, so the label on a website may not match the FIDE definition exactly. For official play, check the current FIDE Laws of Chess or your national federation's rules, since they are updated from time to time.\n\n## Reading time control notation\n\n| Notation | Meaning |\n|---|---|\n| 5+0 | 5 minutes each, no increment (\"sudden death\") |\n| 3+2 | 3 minutes each, +2 seconds per move |\n| 15+10 | 15 minutes each, +10 seconds per move |\n| 90+30 | 90 minutes each, +30 seconds per move from move 1 |\n| 40/90, SD/30 | 90 minutes for the first 40 moves, then 30 more minutes for the rest of the game |\n| G/60;d5 | US style: game in 60 minutes with a 5-second delay |\n\nMulti-stage controls are common in classical tournaments. A frequently used FIDE control is 90 minutes for the first 40 moves, then 30 minutes added for the rest of the game, with a 30-second increment from move one. Tournaments state their control in advance, so always read the event rules.\n\n## Increment vs delay\n\nWithout any extra time, a player who is low on the clock can lose a completely winning position just because they cannot physically move fast enough. Increments and delays fix that.\n\n### Fischer increment\n\nNamed after Bobby Fischer, who proposed it. A fixed number of seconds is **added to your clock after each move**. If you move quickly, your time can actually go up. This is the most common system in online chess and in FIDE events.\n\n### Bronstein delay\n\nNamed after David Bronstein. After each move, you get back **the time you used, up to the delay amount**. With a 5-second Bronstein delay, if you take 3 seconds you get 3 back. If you take 10 seconds you get 5 back. Your clock can never gain time, only hold steady.\n\n### Simple delay (US delay)\n\nCommon in US Chess events. When your turn begins, the clock **waits for the delay period before it starts counting down**. With a 5-second delay, if you move within 5 seconds, your main time does not drop at all. Like Bronstein, it never increases your total.\n\n| System | What happens | Can your time go up? |\n|---|---|---|\n| Fischer increment | Fixed seconds added after each move | Yes |\n| Bronstein delay | Time used is refunded, up to the delay | No |\n| Simple (US) delay | Clock waits before counting down | No |\n\nBronstein and simple delay give the same practical result in most situations. The difference is mostly in how the display behaves.\n\n## What happens when the flag falls\n\n\"Flag fall\" means a player's time runs out. The name comes from old analogue clocks, which had a small flag that dropped when the minute hand reached the top.\n\nThe basic rule under FIDE Laws:\n\n- If your time runs out, you **lose**, as long as your opponent claims it or the arbiter notices.\n- **Exception:** if your opponent cannot possibly checkmate you by any legal sequence of moves (for example, they have only a king left), the game is a **draw** instead.\n\nExact procedures differ between FIDE and US Chess, and between over-the-board and online play, especially on who must claim the win and when. In tournaments, the arbiter or tournament director makes the final call.\n\n## Which time control should you play?\n\n| Your goal | Try |\n|---|---|\n| Improve your understanding of chess | Rapid (15+10) or classical. You have time to think |\n| Have fun in a short break | Blitz (3+2 or 5+3) |\n| Practise quick pattern recognition | Blitz or bullet, but do not rely only on these |\n| Teach a beginner | 15+10 or longer, or no clock at all at first |\n| Casual game with friends who move at different speeds | Give the stronger player less time (time odds) |\n\nMany coaches suggest that improving players spend a good share of their games at slower controls, because fast games reward instinct but leave little room to calculate or learn from the position.\n\n## Tips for casual games with an online chess clock\n\n1. **Put the device between you**, beside the board, where both players can reach it.\n2. **Press the clock with the same hand you move with.** It is a common tournament convention and avoids arguments.\n3. **Agree on the rules first.** Increment or not, touch-move or not, what happens with illegal moves.\n4. **Use time odds** to balance a stronger and weaker player, for example 10 minutes vs 5 minutes.\n5. **Pause for interruptions.** A browser clock is easy to pause if someone knocks the board over or the phone rings.\n6. **Go full screen** so the remaining times are visible at a glance.\n\nOn the [ClockAura chess clock](/chess-clock) you set each player's starting time and increment, then tap your side of the clock to switch. It works for other turn-based games too, from Scrabble to debate practice.\n\nFor quick timing outside chess, our [stopwatch](/stopwatch) and [countdown timer](/countdown-timer) cover most needs, and the [multiple timers](/multiple-timers) page is handy for game nights with more than two players.\n\n## Frequently asked questions\n\n**What does 3+2 mean in chess?**\nEach player starts with 3 minutes, and 2 seconds are added to their clock after every move they make.\n\n**Is 10 minutes blitz or rapid?**\nUnder FIDE definitions, a game of 10 minutes per player with no increment is blitz, because blitz is 10 minutes or less. Once you add an increment, use the base time plus 60 times the increment. 10+5 counts as rapid.\n\n**What is the difference between increment and delay?**\nAn increment adds a fixed amount of time after each move, so your clock can grow. A delay either pauses the clock briefly before it runs or refunds time used, but your clock never grows beyond where it was.\n\n**What is bullet chess?**\nBullet is an informal name for very fast games, usually with less than 3 minutes per player, such as 1+0 or 2+1. It is not a separate category in the FIDE Laws.\n\n**Do you lose if your time runs out?**\nUsually yes. The exception under FIDE rules is when your opponent has no possible way to checkmate you, in which case the game is drawn.\n\n**Can I use an online chess clock for a real board game?**\nYes. Set both times on a tablet or laptop next to the board, and each player taps their side after moving. The [ClockAura chess clock](/chess-clock) works without sign-up.","coverImage":"https://images.unsplash.com/photo-1501139083538-0139583c060f?w=1200&auto=format&fit=crop&q=80","createdAt":"2026-10-09T17:25:37.344Z","excerpt":"What does 3+2 mean?
