Rules, controls and help for Breakthrough

One thing to notice as you play

The board gives you the information needed for the next action. Capture only one square diagonally forward. Straight captures and backward moves are not allowed. Keep the goal in mind before your next move.

The challenge in front of you

Read the position before choosing your next action. Reach the opposite back row with one of your pieces, or capture all opposing pieces.

Making your moves

  1. Each player begins with sixteen pieces on the nearest two rows of an 8×8 board.
  2. Blue moves upward and red downward. Move one square straight or diagonally forward into an empty square.
  3. Capture only one square diagonally forward. Straight captures and backward moves are not allowed.
  4. Reach the farthest row with any piece, or remove all opposing pieces, to win. Captures are optional.
  5. Choose a computer opponent or two players on the same device. New round resets the board.
