Keep the tiger cubs happy for as long as you can to win this game. You play a zookeeper taking care of some pretty demanding tiger cubs. You start out with just one cub, to get used to the game. When your tiger cub needs something, it will appear in a thought bubble over his head. At the top of the screen, there is a toolbar with all of the icons you need to take care of your tiger. Drag the item he wants and click it on him. He will be happy and your success bar will fill up. If you let a need go unfilled for too long, you get one unhappy cub mark at the top of the screen. Get three and the game is over.
