A virus has invaded your system. Can you get rid of it before it can multiply itself? Say good-bye to the virus by sliding it off the game board. However, this game is more mind challenging to solve than it looks. As you can 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! Nobody is immune to the infectious fun this sliding game brings. 60 challenges will keep your body and mind healthy. A travel bag makes it easy to take this game along with you, and convenient to store the colorful game pieces. Young and old alike are quick to "catch the bug", once you've started playing you won't want to stop!
