Occupy all yellow flags to win the game. Your color is blue. Your opponent's color is yellow.
Sword defeats axe, axe defeats pike and pike defeats sword. It's like rock, paper, scissors.
You can summon your units at blue flags.
Stay tuned to this game:
In the next screen you will pick 10 units. Your units will enter the game in the same order as you pick them.
