Firsty, you have to create a soldier, per soldier price is 5 matic. You attack other player's soldiers and kill them, earn their money. 40% of it is reflected as power to your soldier, 50% is reflected as gain to the balance, as your soldier gets stronger, he hits other soldiers more and the stronger soldier attacks the weaker soldier by calculating the square of the power difference, so the stronger soldiers gain more by cutting more soldiers. The aim of the game is to strengthen your soldier and then earn unlimited money.
Good luck!
