Put your body and mind to work and get rid of the red virus!. A virus has invaded your system. Can you get rid of it before it can multiply itself? This game is more mind challenging to solve than it looks. As you'd imagine, there is not a lot of room in a cell, so the virus and all different shaped molecules are constantly blocking each other's path. And what's more, everything moves in a special way: the tiles can only slide diagonally and can move in group!. No-one is immune to the infectious fun this sliding game brings. The 60 challenges keep your body and mind healthy. A travel bag makes it easy to take this game along with you, and convenient to store the colourful game pieces. Young and old alike are quick to "catch the bug" - once you've started playing you won't want to stop.
