Numbers And Cannons Make 10

Shoot the barrels with numbers that along with the numbers on the barrel add up to 10. Be careful with the numbers you choose as well as aiming as there is limited ammunition. There are 25 levels for you to complete without any time limit.

Destroy all barrels in each level by hitting the barrel with a number such that the barrel's number and the number shot from the cannon adds up to 10. 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.
