Enter or buy access code

You have to buy an access code. Afterwards we will send it to you by e-mail.
Afterwards you can start right away!

The access code is valid after the purchase for an unlimited time until the game is completely played through.
So you can also interrupt the game as often/long as you want.

If you see this screen, you have not yet entered an access code or you have already solved all the puzzles over an hour ago.
If you have interrupted the game you have to enter the code again.
