Another version of the old-known naughts and crosses. There are 9 fields instead of the single one, each of these fields is a cell of the global field. To win on the global field you have to win the set of games on three small fields.In other words it becomes square naughts and crosses.
There are several play modes: Human being vs Human being, Human being vs CPU and CPU vs CPU (for the case if you are curious to know how your device will fight against itself).
The Computer game player has two intelligence levels: general (CPU) and simplified (CPU-kid). CPU-kid mode is good enough for the children that just get to know the base of the logical games.
Tap shifts the rival according to his name: Human, CPU or CPU-kid.
