Build your raft trying to destroy rafts of enemies. Keep building so that you can head the leaderboard on your server. Earn coins and buy flags for them in the store. Your task is to sail across the ocean and collect construction materials for your raft along the way. You can easily recognize them - these are squares with a plus sign on them. As soon as your raft becomes a decent size, try to defeat your opponents by swimming closer to them. If your opponent has a raft much larger than yours, run. Also, beware of the huge monster - Kraken. If you swoop down on its tentacles, you will inevitably die.
