#100 – Curvy Tuttminx V2

Description

This page is about a Curvy Tuttminx V2. The key feature of this Tuttminx is: it physically stops illegal moves.

Just like other random products, a twisty puzzle is associated with its defined functions. The motivation here is: to be a well defined product, it is desirable to not only define what it is but also rule out what it isn’t.

Illegal moves are rotations that are not intended but practically possible. For example, rotating a corner alone on a nowadays’ 3x3x3 cube is usually possible but not intended. In Tuttminx, the situation was not at all obvious and brought constant frustrations to users. Naturally you want to rule them out physically.

The method used in this Tuttminx looks nothing new but is in fact a generic design pattern that will benefit a number of designs.
