Twice a game the tide floods the outer ring and the board shrinks.

The tide comes in twice

Rising Tide Chess is real chess played on a shrinking island. Twice during the game the tide rises and floods the outer ring of the board, washing away every piece that stands there. First the board shrinks to six by six, then to four by four. Plan your pieces and your king around the countdown, because the tide always arrives on time.

The countdown turns red at two moves. A red line marks the ring that floods next, and a drop warns you about each of your pieces standing on it.

Use the buttons or the slider. With the keyboard: the arrow keys on the slider step one move at a time, Home and End jump to the start and the end.

The moves are one prepared game. The tide, the washed-away pieces and every move follow the app's own rules.

An eight by eight board with the tide countdown above it. At two moves the countdown turns red and a red line marks the ring that floods next. On the last move before the tide each king steps off that ring, then the water sweeps in, washes away the pieces standing there and the board shrinks to six by six. The same happens once more, down to four by four.

How it works

Rising Tide Chess app screen: Play chess as usualRising Tide Chess app screen: Watch the tide countdownRising Tide Chess app screen: Get your king out in time

  1. Play chess as usual

    Full chess rules, including castling, en passant and promotion. Castling is only possible before the first tide, and pawns promote on the farthest remaining rank.

  2. Watch the tide countdown

    After the 12th move of each side the outer ring floods, then six moves later the next ring floods. Pieces on flooded squares are removed.

  3. Get your king out in time

    On your last move before a tide, your king must be off the doomed ring, just as it must not stay in check. On the final 4x4 board, ten moves each without a capture end in a draw.
