Do you have a good visual memory? This game does allow you to test it. You play against a machine having 8 branches, each equipped with a coloured half moon. The game is easy. The machine does light on the half-moons one after the other in a given order. You have to replay the same sequence by clicking on the half-moon in proper order. If you do it right, the machine re-pay the whole sequence and add more half-moon(s) to it! The game has several levels. At level 1, the machine starts with 1 colour and add 1 more colour each time you give the right sequence. At level 2, the machine starts with 2 colours directly, and will also add 2 colours each time you win, and so on with further levels... You have five memory-jokers. When you make an error, the machine replay the whole sequence to give you a chance to correct your error, but then you loose a joker. Keep concentrated!
