The Tessarisis (Tess-ar-isis) - The fourth puzzle in the isis puzzle series. The Tessarisis is a grid style cube with a secret that has a numeric connection with something that is not an object and cannot be physically approached, but can be observed.
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 2015. The puzzle invented by Andrew Reeves with architectural expertise provided by Stephen Miller (M.I.Exp.E.).
The Tessarisis is much heavier than any of the previous puzzles in the series and is the most advanced in the series. The Tessarisis will be available in black and gold and gold and blue color ranges and presented in the new black leather presentation boxes.
