Set the angle and power of the cannon to blast a beaver into the target pool.
You begin with 5 shots. Each miss will subtract one shot. Each hit will give you half a shot back.
Damn Beavers are pretty cheap. It takes a couple of shots just to get the range.
The backgrond scrolls past quickly but it is the only clue the game gives about the distance to the target.
It won't be much help with the first pool and all you can do is adjust your angle or power to find the correct range.
Note and remember the location of the current pool against the background as it sets up.
Compare the next pools position against your memory of the last pool.
At least you'll know whether or not to increase or decrease the strength of the cannon.
Have fun. WiseAcre's flash game collection is a perfect waste of time.
