Control your boat with the left and right arrow keys. Run into whales to collect their skin. After collecting their skin, run into a trading post (right hand side of the screen), to collect gold. Albino whales are very rare, Grey whales the next rarest, and Blue whales the least. When depositing whale skins, you must wait 10 seconds between deposits for Albino skins, 6 seconds between deposits for Grey skins, and 4 seconds between deposits for Blue skins. If you attempt to stop at a trading post when you don't have skins of that variety of whale, you will be forcefully booted from the game. (Sorry if you think this is unfair, it is the easiest and quickest anti-cheat method.) You win when you have 5000 Gold.
