The game “Pro Tribs io” is based on the eternal opposition of three elements: water, earth and fire. At the very beginning, you can choose which of the elements to play, and then your character will take on the appropriate appearance. Tribs IO rules are a bit unusual. As in other io projects, here you need to kill rivals to earn points and break through to the first place in the ranking, as well as multiply by division to get your tribe. But in “Tribs io” you can not destroy anyone. Water acts only on fire, fire on earth, and earth on water.
