I am at the Sudoku puzzle and according to the walkthrough it is suggested I take a picture of the lock and work on it on the ship. I don't have a camera. Have I missed something?

I had to check the walkthrough on this one.

The walkthrough states:
I recommend that you take a picture of the lock and work on it outside the game. - not at the ship.

It means that since this is a timed puzzle and very complicated, it is best that you take a picture of the puzzle; exit the game and do it at your leisure.

You can take a picture of the puzzle by pressing the key on your keyboard labeled "Print scrn".
Then open Start - All Programs - Accessories - Paint program. Then select "paste" on the Paint program.
You will then see the puzzle and can work on it. You can also print that puzzle on paper.

This might be too much for this grandma but I will give it a shot. Thanks MaG

You want a saved game?

I did finish the puzzle but now but don't have enough air left to make a second dive to get the Easter Egg. Do I go back to the last save before this one to have enough air?

Go back to the resort and fill your air tank.

Thanks a bunch MaG! Lynne

Have fun, Lynne.
