In order to start a game with an opponent for a reward, use the "Players in game" button in the menu that you see in front of you.The essence of the game with an opponent is to play with the help of an individually built level on the map. One participant in the game builds a level of the map, and the other participant in the game passes the built level on the map in the game. After successfully passing the level in the game, you receive a reward from the opponent, if you failed to pass the built level of the game by the opponent, then you make a reward to your opponent.
When the game starts, you will have a limited time to pass the labyrinth. The controls in the game are quite simple and intuitive for the player.
