The game starts by placing 1 colour of each of the 4 colours in the middle, so that they form a square. Then the first player starts by placing a ball of his colour at the top of the field, next to the balls that are already there. If balls are "trapped" between this colour, or if there is a ball of that colour at the beginning and the end of a line (possible in all directions), then all balls in between may be rolled over to the same colour. Roll it! The game continues in a clockwise direction until the board is full. The one who now has the most balls of his colour visible, wins.
