Toriko is the most addictive puzzle game ever created. It’s a 1V1 game where you must arrange a flock of birds to clear a path for them to pass through and escape from a tower. As soon as the path is cleared, the birds will fly down and you must arrange them so that they land on the same blocks.

This is how it works:

Your goal is to clear as many blocks as possible, before your opponents do. If you get three or more same blocks on the same level, you can eliminate them and win the level.

The rules are simple, but they can be very difficult to master.
