How to play Pikan.iO
From the first view Pikan seems to be more complicated that usual games from our io games list, because there is only one place where you can do damage for your opponent, i.e. small part of its head. Otherwise you cannot make a damage, only ricochet. However, your ammo will regenerate shortly, so do not have fear. After you increase in size by consuming passive orbs, dropped by opponents, you will earn more maximum shots, and also you will grow in size of triangle. Your vital spot will make it harder to avoid enemy players projectiles.
