These three games in one are variants of the classic Tetris game.
FLOOD is a waving version - it's a matter of moving like the waves in the sea.
Game two is all about eating. Nuts for squirrels, bananas for monkeys, each animal has its corresponding food. And they are hungry. Put them together as soon as possible!
The third game is closer to the classic Tetris, playable by one or two human (if two, the screen is divided to play in parallel).
