Numbers and Cannons Even Odd

Identify the numbers on the barrels as being even or odd. Load up the cannon with that type of ammo and fire away. 25 levels to complete without any time limit.

To shoot the cannon, you'll need to load it with the correct "even/odd shot" and then hold down the left mouse button or your finger to aim and set power. Release to fire the cannon. There's also a video available via the Walkthrough link that shows solutions to all of the levels in case you get stuck.
