In the game Stone Merge you will solve a certain type of math puzzle. Before you on the screen you will see a field divided into cells. In each of them there will be a stone in which a certain number will be inscribed. You will need to carefully examine the playing field and find standing next to the same items. Now moving them one cell in any direction you will need to connect the same stones with each other. This will create a new number and a new stone.
