Noah's Ark

Link to game: 

Controls:
Space bar to get a random animal.
Mouse click to drop it where you want.

Goal:
Pile as many animals as you can on the ark.

Your score is based on:

• total number of animals in the ark
• unique animals in the ark
• unique animal pairs in the ark
• height of tower

Get a streak of successfully placed animals for rewards to build your ship.

You won't lose if animals fall in the water—you'll just have to build back up again.
