Lines is a multiplayer chromecast game, where the goal is to survive longer then your opponents. You have to dodge other lines or outsmart your opponents by using your superpower at the right time.
It is a variant of "Curve Fever" and "Achtung die Kurve", only this time you can use your phone as controller. The principle is the same, you and your family or friends sit arround one screen (you TV) and connect with your phone to the chromecast. When everyone has entered the game and are ready to play, the host can start the game.
