Yokka Wars is a turn based strategy game. You start with a friend or two on an island that simply is not big enough for you and your enemies. So you grab neutral provinces and raise armies, plunder treasures, and engage in combat. The rules of the game are simple enough and you sure master them in a minute. Mastering the game, liberating all islands, and winning the Big Campaign will take a LOT longer.
The rich enemy homelands field huge armies and by force alone you will not win much. You have to outsmart the computer, avoid towers, isolate hostile forces, occupy provinces of strategic importance, and sacrifice lesser ones to preserve your troops for a final onslaught on the fortified capitals of your arch enemies.
