Rings Blast-Easy Match 3 Game

The Champion of time killer!
Rings Blast is a unique new approach to the "match-3" style of game-play that you are used to.
In Rings Blast you have to match the rings color in any direction. There are bigger and smaller types of rings that you have to place on the slots (dots) on the screen or discard them. When all the slots are filled with rings, and none of the ring colors match, then its "game over”.
Is this simple ? Yes, but not easy to get high score as you think!
