Before there were various devices, a piece of paper and a pencil or pen were enough to play Dots n Lines. In the age of technology, paper and pen have been replaced by screens of tablets and smartphones. Now you can play the game anywhere, and if before you needed a partner, now the game itself can become your rival if you choose the single player mode. The task is to set the maximum number of squares on the playing field, or at least more than the opponent's. To do this, connect the dots with lines, and when the fourth line is set, you will get a square in Dots n Lines.
