How to play Kassle

Kassle is a basic board game similar to tic-tac-toe or connect-four. The board is a 5x5 grid, and each of the two players has a unique game piece.

The players alternate turns. A turn consists of either:

  1. placing a piece on the board or
  2. shifting a row/column

The first player to get five pieces in a row (vertical, horizontal, or diagonal) wins.


Player 1 places the first game piece on the board

Fast-forward a few turns, and the board could look like this:

Player 1 decides that, rather than place a piece, he will shift the top row to the left. The piece on the far-left end wraps around to the right, and the piece on the right moves over one cell to the left.

Player 1 wins!
