Numbers and Cannons Rounding Math Game

Round the numbers on the barrels and shoot them with that rounded number. Be careful rounding the barrel numbers and aiming as there is limited ammo. There are 25 levels for you to complete without any time limit.

To shoot the cannon, you'll need to load it with a "number 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.
