Components

• 7×7 board.
• 5 light pieces.
• 5 dark pieces.

Game play

• Players take turns to move one of their pieces.
• Pieces have three possible speeds: 1, 2 or 3.
  • Noted by the number of dots next to that piece's starting space.
• If a piece moves over an opponent's piece, the active piece moves one space further than the opponent's piece, regardless of its speed.
  • The opponent's piece returns to the start or conversion line.
• A piece that moves to the other side and back to the start line is removed from the game.

Conversion line

• Pieces that reach the opposite side of the board are converted.
  • The active piece changes direction.
  • The active piece may also change speed:
    • 1 -> 3
    • 2 -> 2
    • 3 -> 1
• When a piece is sent back, it only moves back to the conversion line.

Game end

• The first player to move four pieces back to the start line wins.
