Each level starts with 6 sets of 2 identical pictures positioned randomly on the play field. It is up to you to memorize the position of the pictures. Your race against the clock starts as soon as the pictures are covered up. Match the pairs as quickly as possible by clicking on identical pictures. The pictures will be permanently uncovered as soon as you have clicked on two identical pictures after each other. Watch out! Time is your biggest enemy in this game. If you do not succeed in matching all the pairs within the given time, your game is over.

Use your mouse to match the pairs by clicking identical pictures after each other.During the game you can use the following keys:

R	This ends the current game and starts a new one.
S	This starts or stops the sound.

The score achieved in a level is dependent on the mistakes made and the remaining time. The score for clearing a level without mistakes is 1000 times the level, so the score for clearing level 3 without mistakes is 3000. For every mistake made while playing the level, this score is divided by 2. So if level 3 is cleared with 2 mistakes the achieved score is 750 (3000/2 = 1500, 1500/2 = 750). After calculating this score, the time bonus is added.

Clearing a level will bring you to the next. Each subsequent level offers you less time to memorize the position of the pictures. Also the time for you to match the pairs will be shorter and shorter.
