World of the Rings
Destroy all the figures on the board. Rotating the circles with figures, place them so that you could make a line of one type figures, inside of the trough or crossing it. You are limited in the number of attempts. After each unsuccessful turn (when you do not manage to destroy any figure), the number of attempts decreases. When attempts reach zero, the new figures appear. Having removed all the figures of one color, you will not see them anymore. For each color removed, your score is doubled.
