Your goal is to collect the buoys/life rings for points and avoid mines. Each square may contain mines and is marked by community voting from 'safe' (blue) to 'deadly' (red). Marking a square correctly will earn an extra life, up to a maximum of seven, giving you a better chance to survive and get a higher score. On the other hand, you may wish to deceive other players and mark squares as unsafe, giving you the EDGE over other players by killing them sooner.
