Complete the puzzle on the chest. Once the chest opens, take the clock hand inside (red dot).
Look at the clock. Drag the hammer to the wooden planks to remove them.
Add the clock hand to the clock.
Tap the eye to see BOTH clock hands. The clue when you tap the "?" tells you "You may leave at 666". Change the clock to 6:06 (there is already an 18, which is the first 6.
Tap and hold the minute hand to move it.
The level will complete once the clock reads 6:06 (Make sure the eye vision is on!)
