If you do not have time to finish the puzzle now, you can save your progress so far and then resume solving the puzzle the next time you connect to the Internet.
There are two ways to save your progress:
(1) Bookmark THIS page (not the puzzle page) by any of the usual methods, or
(2) Save THIS page (not the puzzle page) to your hard disk.
To save your progress to your hard disk, go to the FILE menu on THIS page and select SAVE AS . . .
A SAVE AS . . . window will open with the file name SAVEME.HTML already entered. You can change the name if you want to, but it must end with .html.
Next, use the SAVE IN: box at the top of the window to select where you want to save the file on your hard disk.
Complete the save by clicking on SAVE in the bottom right-hand corner of the window.
When you reconnect to the Internet and want to continue solving the puzzle, either select the bookmark you made or open the page you saved to your hard disk.
THIS page will reopen and you can continue working by clicking this link: Saved Puzzle.
On some browsers you may need to press Reload/Refresh after following the link.
Please note that you must be connected to the Internet in order to work on the puzzle on your computer. If an Internet connection will not be available or convenient, you can print out the puzzle now and solve it later in the traditional way -- on paper. You can print out the solution, too, if that won't impose too great a strain on your willpower!
