Similar to its predecessor Sumouse, Terry Cavanagh's Kozachok is a two-player only arcade game in which the first person to score five points is declared the winner. A point is scored by the player who claims the most walls after a five-second round, but when things are at a stalemate then the next round will just begin with no advantage given to either side.

Some additional rules apply as well. If both parties collide with each other, then the round ends immediately and a point is deducted from each of their scores. Occasionally the two players are separated by borders that prevent collisions from happening, while other times they both occupy the same area and will have to jostle for supremacy over the walls before the five seconds are up.
