Splix.io is a colorful 2D io game where you control a line and start with a quad as territory. The goal of the game is to expand the own territory through connecting the start and end of the line with the already existing piece of area. But be careful, while doing this you become vulnerable to other players who will attack by colliding with your line to crush your whole territory. If you yourself touch the enemy territory you will not be hurt and if you cross an incomplete line of an opponent he will lose and his claimed area will disappear.
If you have read the text above you should be already ready to go. The line you are controlling moves automatically to the last known direction and you can change the direction with WASD. A good beginners guide is to expand your own territory in small segments since you will be able to react faster for incoming enemies, but it will be also more effective and safe if you are on the offensive where the opponent should be on the advantage with a larger area. You should also not underestimate players who look defenseless at the first sight, many will try to bait you and trap you, but at the end it’s all about having fun and the more you risk the bigger the reward will be, if you survive.
