ZEN is an innovative puzzler with original gameplay that combines precision, reaction and inventiveness. Your goal is to guide the ball though a labyrinth towards the gates, avoiding collision with sparkling blocks. Move the ball using combination and sequence of waves, the number of which is limited for each level, so make sure to choose the shortest way. And cut corners.
