Rush is played on a Go board (19x19). Other odd-sized boards can be used like 9x9, 11x11, 13x13 or 15x15.

The goal of Rush is to have more stones than the opponent when the board is completely filled with stones.

No draws are possible in Rush.

The game begins with an empty board.

Each player has an allocated color: Black or White.

Starting with Black, players take turns placing a stone of their color on any empty intersection of the board.

A player must never place a stone on an intersection if two or more horizontally or vertically adjacent intersections are occupied by player's stone and there is no horizontally or vertically adjacent intersection occupied by an opponent's stone.

If a player places a stone on an intersection with two or more horizontally or vertically adjacent stones (both player's and opponent's) then he gets an extra turn. In this case a player must place another stone on the board if he has legal moves.

Below are several examples:

A white stone can be placed where the transparent stone is shown because there are less than two horizontally or vertically adjacent intersections occupied by white stones. The player doesn't get an extra turn after placing a white stone on the mentioned intersection because there are less than two stones adjacent to it.	A white stone cannot be placed where the transparent stones are shown because there are two horizontally or vertically adjacent white stones and there are no adjacent black stones.	A white stone can be placed  where the transparent stone is shown because at least one black stone appears on a horizontally or vertically adjacent intersection. The player gets an extra turn after placing a stone on the mentioned intersection because there are two or more stones adjacent to it.
