The goal of the game is to reach the last tile entitled ‘END’. To do that, you move from one tile to another by removing all the marbles on the destination’s tile, you can only move horizontally and vertically.

When you move to a tile filled with marbles, you have 300 seconds (5 min) to remove all the marbles. If you fail, you lose a life and all remaining marbles stay there, but if you succeed on time you reach this tile.
