Pandemiac is a game where different viruses appear on a board. You can move them across it by pressing the keyboard arrows or by swiping left/right/up/down on mobile devices. Although you can choose the general direction of the movement, you can't control individual viruses direction. When moving viruses to a certain direction, all viruses on the board will follow that direction. So, plan your moves accordingly.

When two similar viruses collide one another they die and disappear. Your job is to keep the board clean of viruses as much as you can. Each time you make a move a new virus appears. When no empty cells left and you can't make any move the game ends.
