There are a couple of different types of Zakks to avoid; some move one square at a time, others move two at a time. There are also two different modes to the game. In Puzzle mode, you use your wits (and sometimes, bombs!) to clear out the Zakks and avoid annihilation. In Marathon mode, Martok is confronted with a field of Zakks, all of whom must be cleared…but also gains the power of teleportation. Fun times! If all the Zakks are cleared and you're still standing, you move on to the next challenge".
