Retrogrid io is an io game of a King of the Hill type. You've got to hunt for a King to get his Crown. As soon as you become a King make sure no one hunts for you :)
How to Play
The main goal of the Retrogrid io is to get maximum points. Points are given when you have a Crown. The more you keep the Crown in your hands the more points you can earn. Don't think it easy to hide with a crown. It glows as a torch and is visible probably even from the space, so every, EVERY player will chase you.
Look around, even when no one has the Crown it emits light. Run towards the light to get it first! Be smart and fast to keep it and to get it again if lost.
