You win a match by owning more locations than your opponent. This is done by gaining more points on that location than your opponent at the end of the game. Points at each location are decided by the power of heroes at this location, the ability of heroes on the ground, and the effect of this location.
You win a battle when:
※ You win 2 or more locations
※ Each player wins one location with the third location tied, but you have more overall power on the board.
※ The other player retreated.
