Goliath Rolit

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, in other words, 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.
