The game consists of a 6×6 grid with tiles filled with colored marbles and an informative panel on the left.
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.
The score represent the time you took to complete the tiles (including time bonuses). For example, if you had 50 seconds left when you completed a tile, you get 250 points (300 50), if you fail a tile you get 300 points and still have to finish the tile. Obviously, the best score is the lowest.
On the panel to the left you have 3 containers for crystals of each primary colors (blue, red and yellow), and you have a timer on the bottom.
So when you click on a tile you want to complete, the timer appears and start, that's where the fun begins. A set of 5 cards appears, you must choose only one card and you have 10 seconds to do so, after that, 5 new cards will appear.
