The goal of "Gears Of Fate" is to reach the red square with the green ball. This is reached by rotating the board, while undo is possible while the board still rotates.
Colored tiles are removed when three of them are regrouped. Grey tiles can not be removed at all. Dark colored tiles are removed once all tiles of the same color have disappeared.
This entry works on REAL HARDWARE where you have better sound but vector animations are slower. If you run this in an emulator: Using 12Khz WAV makes some emulators go nuts. Seems to work fine with NEOPOP 0.71 on Windows; Sometimes slower, sometimes faster than real HW.
