Instructions
Play through the game until you reach the 14th and final dive. You'll see a combination lock at the bottom of the screen. After a few seconds, a number will appear in a yellow square below the safe handle
Find an item that corresponds to that number and click on it. For example, if the number is "5," you might have to click on a "V" (the Roman numeral 5), a hand (because it has five fingers) or a playing card with a "5" on it. The exact objects change every time you play the game.
Find the item that corresponds to the number each time a new number appears. You need to find six numbers in all to open the safe.
