Rapid 15|10

How to play

15 minutes plus a 10-second increment per move — the official FIDE World Rapid format, with room for real strategy in every phase of the game.

Rules

  • Tap or click a piece to see its legal moves highlighted, then tap the destination — or drag the piece directly.
  • Both sides start with 15 minutes; every move you make adds 10 seconds back to your own clock.
  • All standard chess rules apply: castling, en passant, pawn promotion, threefold repetition and the 50-move rule.
  • Checkmate the computer, force a resignation, or win on time to take the game.

Tips

With a generous increment, you can afford to calculate critical positions properly — save your deepest thinking for the moves that actually matter.
