You are playing Splix.io
I am pretty sure that you have at least once played a game where you have to reveal a picture by drawing shapes. It was a long time ago, but human remembers his/her favorite things. That is why you will definitely love Splix.io. The idea is almost identical, but here you play against real people and there is no picture in the end. What you get here is drawing your own territory. Bigger it is, more points you will get. You can invade an empty area, as well as, steal someone’s part. But keep in mind that they will not like it. You are vulnerable while drawing. If somebody hits your tail during this process, you will lose. What you have to do, is to expand slowly, but safely. No-one will get you if you do so. The controls are very simple, as always. Use WASD or arrow keys to move.
