Chess Clock
A clean, responsive chess clock for over-the-board play. Choose from standard presets - bullet, blitz, rapid, or classical - or set your own custom time and increment. Tap either side to switch clocks. Supports fullscreen mode for easy use on tablets and phones.
Professor Archer says: Time management is one of the most underrated skills in chess. I have seen countless students play brilliant moves for 30 minutes, then blunder everything in time pressure. Use this clock when you play practice games at home, and pay attention to how you distribute your time. The best players spend their time on critical moments, not routine moves.

Using This Clock for Over-the-Board Games
Set the time and increment, place the phone or tablet beside the board, and after each move tap your own side of the screen to stop your clock and start your opponent's. That mirrors a physical chess clock, where you press the button on your side with the same hand that moved the piece. Fullscreen mode hides the browser chrome so a stray tap does not navigate away mid-game.
Two house rules keep casual games friendly: agree before the game what happens on a flag fall (in formal rules, running out of time loses if the opponent has mating material), and pause the clock for any dispute or interruption rather than letting it run. The pause and reset controls are one tap away for exactly that reason.
Choosing a Time Control
The notation is minutes plus increment: 5+3 means five minutes on the clock and three seconds added after every move you make. Bullet (under 3 minutes) is reflex chess, thrilling and terrible for learning. Blitz (3-10 minutes) is where most online chess lives; see our guides to blitz chess and bullet chess for how the fast formats change strategy. Rapid (10-60 minutes) leaves room to actually think, and classical (over an hour) is the tournament standard.
If you are playing to improve, 15+10 is the sweet spot: long enough to calculate properly, short enough to finish a game in half an hour. Increments also remove the ugliest part of time scrambles, because a player who keeps finding moves always has at least a few seconds to make them.
Time Management: The Skill the Clock Teaches
Strong players do not spend time evenly. They bank it in the opening by playing prepared or natural moves quickly, invest it at genuine decision points (usually when pawn structure or material is about to change permanently), and keep a reserve for the endgame. A good habit: if you catch yourself thinking longer than two minutes on one move in a rapid game, you are usually cycling between the same two candidate moves, and it is time to pick the safer one and move on.
Playing practice games with this clock, even against a friend at the kitchen table, builds the internal alarm that online players often lack over the board, where no interface shows your remaining seconds ticking red.
Frequently Asked Questions
What are the standard chess time controls?
Bullet is under 3 minutes per player, blitz is 3-10 minutes, rapid is 10-60 minutes, and classical is over 60 minutes. The most common online time controls are 3+0 (blitz), 5+3 (blitz with increment), 10+0 (rapid), and 15+10 (rapid with increment). The number after the plus sign is the increment - seconds added after each move.
What does increment mean in chess?
Increment is the number of seconds added to your clock after each move. For example, in a 5+3 game, each player starts with 5 minutes and gains 3 seconds after every move. Increment ensures that players always have some time to think, preventing games from being decided solely by who can move fastest.
Which time control is best for learning?
Rapid time controls (10-15 minutes with increment) are generally best for learning. They give you enough time to think about your moves carefully, but not so much time that games drag on. Professor Archer recommends 15+10 for students who want to improve, and 10+0 for those who want a faster-paced but still thoughtful game.
Can I use this chess clock on my phone?
Yes. The clock is designed for touch screens: each player taps their own half of the screen to switch. Fullscreen mode removes browser controls, and the display stays awake during the game. It works on phones, tablets, and laptops with no download or account.
What happens when a player runs out of time?
The clock shows a flag for the player whose time expired. Under standard rules, running out of time loses the game, unless the opponent has no possible sequence of legal moves that could ever deliver checkmate, in which case the game is drawn. For casual play, agree on the rule before you start.
