In Super Scribblenauts, if you create an ARCADE MACHINE, you can tap on it and play the arcade game. Here is how to play:

• Missiles will fall from above. Tap them on the touch screen to make them disappear.
• Keep the missiles from breaking through the wall. If a missile breaks all the way through and hits the bottom of the screen, it's game over.
• Sometimes a missile will turn red and fall more quickly than a normal one. You have to be on the lookout for these and tap them as soon as you can.
