Tessarisis| Gold and blue Tessarisis
By Sonic Games UK Ltd
This is the last one we have in this color.
The Tessarisis like the other puzzles in the series has a special key inside the puzzle. All Tessarisis' are uniquely numbered each one with a key code that is required to access the online Tessarisis game.
The Tessarisis is probably the most advanced mechanical puzzle of the isis series of puzzles to date and will probably only be improved on by isis V in 2018.
Coes with the adventure book and a clue to solving the codes.
