Clock Master Description:

Welcome to the art museum! A lot of expensive exhibits are kept here and they give stealers no peace. And only the museum guarding named Cliff can stop them.
Cliffs job is too boring and he falls asleep sometimes. Cliff sets the alarm-clock and if it happens it wakes him up quickly. But sometimes his alarm-clock breaks down
You must help Cliff to wake up. You must set all the clocks of the play ground at right time showed in the upper-left corner of the screen.

But while youre doing it stealers are trying to get in. If you failed to solve the puzzle in time showed on the big clock from the left of the play ground, theyll steal expensive exhibits and would slipped away until Cliff awakes.
