This is the Dots and Boxes, one classical board game. Now you can play it with your friend online! Need at least two players (via two different devices) to play this game.
The game starts with a grid of dots on the screen. The players take turns connecting the dots with lines, and when any player completes a square, that square will now belong to them and will get one extra chance to draw another line. When the whole grid is filled, the player with the highest number of squares wins.
