Jelly Cannon is one of the top flash games that is fun, yet simple game. Shoot the cannon to make the yellow jellies combine into one big yellow ball.
The less shots you take, the more marks you will get. The higher you shoot, the more powerful your shots are.
A cool game online that gets me hooked.
