Fortunately this is not the case. The Isis 1 can be solved without purchasing anything else than the puzzle itself.
The 10 (free) clues may help to solve it. These are available when you log in (to
www.isisadventure.co.uk), right under the Isis image where it says "Download Booklet".
The illusive 11th (free) clue may also help.
Google and YouTube may also help (but without the victorious feeling of doing it yourself).

Yes, but if you have (and understand) one of them, you probably understand how to find out the others.
