Tic Tac Rings

This is a unique new approach to the "match-3" style of game-play that you are used to.
In Tic-Tac-Rings 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 it's "game over".
See what score you can achieve, and if you can make it all the way to #1 on the high scores list.
