Are you ready to take the Brain 1000 visual memory test? come in and get your first set of identical blue tiles. for a moment they will turn around and you will see that on the other side some of them are hiding red cats. Remember their location and after the tiles return to their place, click on those that you think the cats are hiding behind. If you correctly restored the location of the open slabs, you will gain access to a new level and it will be a little more difficult, and so on. One mistake means the end of the Brain 1000 game.
