To start the game, wait for it to load and then click Play. You need to find 5 differences between the dolls for 90 seconds. Cope with the problem - you can move on to a new level button ( Next Level) - find differences between the next pair of dolls.
For each found the difference you get 100 points. For the error (click to the point where no differences) deducted from your account 5 points.
If you deal with the problem quickly, you get bonus extra seconds to solve the following problem. And again, please note that every 60 seconds in the lower right corner places button Hint (Hint). For the remaining few seconds you can have time to find the difference!
