You are shooting at a target with a value of 100 on a linear scale, but the first time you shoot the gun, you do not know how well it is aimed. To compensate, each time you take a shot, you may adjust your rifle by a positive or negative number. Click 'Shoot' and then make an adjustment, if necessary, to get as close to 100 as possible. You have ten shots and will be judged on getting the least variance from 100 for all ten shots.
