Google Developer Day 2011. The Challenge - Doodle the Dymaxion Map
You will be shown some items with their faces down.
Select two of the items by clicking to the item with your mouse.
If both cards are the same, those cards will be removed.
If they are different, remember what is on the item so you can try again.
The game is over when you have matched all of the pairs and all the items are gone.
