Click the START button. The system will display two boards covered with small balls, seemingly coloured randomly with two colours.

Beginner level:
Click a (red or blue) ball on the left board which has a corresponding partner on the right board of same colour and on the same position. The balls will be highlighted. Do so with more and more balls. Together, these ball form a large letter.
Once you know which letter it is, click the corresponding letter in the alphabet given at the bottom of the screen.
Try to click as few positions as possible.

Expert level:
Try to guess the encrypted letter without clicking any positions on the left board.

You can also ask for some hints:
Click the HINT button to be shown part of the encrypted letter. (You will get more hints when you click more often).

Two counters count the rounds and the number of correct hits.
Finally, click the NEXT button to start the next round.
There is no win message. You can play as long as you like.
