In order to complete a level you must complete the contract of patterns given at the base of the screen, within the given time limit, using identical blocks (or circles) for each individual pattern. The number of each of the patterns to be made is given by the number (in red) against it. if you make more than the required number of each pattern, then your score will increase. The score for each of the five patterns is, from left to right: 40, 100, 75, 25 and 10. You also receive a 500 point completion bonus and time bonuses.

The game includes 100 different levels for you to complete. As you complete each level, you are given a code which will allow you to jump directly to that level (and also open up all of the levels underneath that level) from the title screen.

You enter a level code by pressing C on the title screen then using the Cursor Up and Down keys to select the level. Enter the code to unlock. You will then be able to select any level (between 1 and the level whose code you entered) to play.
