Level 64 depends heavily on luck. You need to spend your first moves to destroy the crate in the middle. In order to do so, you need to pick one side (or a corner) and try to make matches only there. We recommend to watch either the bottom-left or the bottom-right corner (depending on where you get better piece combinations) and move towards the center. If you get the first 4-5 matches right, the crate with the tiles will start collapsing on its own due to automatic matches.
Also, do not miss any chance to make power-ups. Firecrackers, bombs and lightnings are very helpful on this level!
