We sell just the Isis Puzzle, not the membership. There is a fee for the membership but it is directly through the manufacture. If you become a member, you can unlock prizes, solve additional puzzles and talk with the online community.
Check it out, it's pretty cool!! https://isisadventure.co.uk
If there are any issues or questions regarding the membership or Isis website, sadly we do not have any support for it. We recommend using the contact form on the Isis Adventure site.
