How to Play - Defend ancient Egyptian civilization! Launch stones to destroy pillars that rain down from above. - Tap the touch screen to stack stones into a pyramid and ready them for launch. - Slide stones of the same color together to merge them and launch them into the air. - Stones fired in rapid succession will merge in the air, forming a large mass with greater destructive power. - The game ends if a pillar crashes into the stone pyramid or the player becomes unable to launch any more stones. - The trick to successfully launching stones is to slide them slowly into place. “Delayed launches” and other special techniques add further depth and enjoyment.
