Online 1v1 chess: bullet, blitz and rapid

On EonChess you play 1v1 chess against another person in games of 1, 3, 5 and 10 minutes per player. We match you with an opponent of a similar ELO and the clock is controlled by the server, so both of you have exactly the same time.

The time controls

There are four time controls, each with its own ELO:

  • 1 minute (bullet): very fast games where reflexes and clock handling matter most.
  • 3 minutes (blitz): high intensity with a little more room to think.
  • 5 minutes (blitz): the most balanced pace between speed and quality.
  • 10 minutes (rapid): calmer games where calculation and technique count.

ELO matchmaking

ELO measures your level and goes up or down after every game depending on the result and your opponent's strength: beating someone with a higher ELO earns more points than beating someone lower. Each time control has its own, because you can be very good at bullet and not as good at rapid.

When you look for a game, the system pairs you with someone of a similar ELO. If nobody of your level is around, you can widen the search to a larger ELO range to find a game sooner.

A fair clock for both players

Time is not measured on your device but on the server, so a slow connection neither gives nor takes seconds. If you disconnect, your clock keeps running: if you come back within 60 seconds and still have time left, the game carries on as normal.

White has 60 seconds to make the first move; if they do not, the game is cancelled and both players get their stake back with no fee.

Full rules and draws

Games follow the official rules of chess, including castling, en passant and promotion. A game ends in a draw by stalemate, insufficient material, threefold repetition, the 50-move rule or agreement between both players. It is also a draw if you run out of time and your opponent does not have enough material to checkmate you.

Free or for a prize

You can play free games, no-stake challenges between friends or games with a USDT prize. If it is your first time, start with the free practice; to see how prizes work, read chess for USDT prizes.

Games with a stake are for adults aged 18 and over only and may be restricted in some countries.
