Pandemiac is a game where different viruses appear on a board. You can move them across the board by pressing keyboard arrows or by swiping left/right/up/down on mobile devices. Although you can choose the general direction of 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 the die and disappear. Your job is to keep the board clean of viruses as much as you can. Each time you move the viruses a new virus appears. When no empty cells left and you can't move the viruses in any direction the game ends.
