Slide the picture-pieces to make the picture whole.
Your aim is, as in many games, to win. You do this by
either removing the pieces of the opponent, or preventing him from making
a move. You can only move diagonally on the white squares.
Normal pieces can only move forward one step at a time, or jumping over one of your opponents pieces, providing there's free space behind. You can repeat this until there's no more moves.
When you reach the other side of the board, your piece turn into a king and can move back, too.
