The main idea is to make a large army with different types of characters, which automatically grows, and the player only chooses who to place.

There are only 3 types of troops: warriors, spearmen and archers, each has an advantageous position for attack range, but this is not a key parameter for proper combat. For each situation, it is necessary to choose the right strategy, based on where the enemy will come from, what another type are nearby, the equality of unit types, and the small abilities of the characters.

The player must only click on one of the three types of troops, which will be installed in a spiral behind the algorithm and create a compact group. Also, for convenience and better results, the player can examine the map to find out where the enemies will come from.

Very simple design so that as many units as possible are visible on the screen and are distinguishable.

The difficulty increases extremely quickly and on average one game takes 3 minutes.
