You have 90 seconds to find 7 differences between the pictures. Once in 40 seconds you have the opportunity to use the hint (Hint). If you can handle the job quickly (you will spend less time than allotted for the job)you will get a bonus of an extra time to complete the next job (Time bonus). Be careful not to click the mouse just - for each such "wrong" click from your account are deducted 5 points.
Seriously? Then try a simplified version of this game is in it for the same time you need to find 5 differences.
