As Successful redesign has a higher chance than a dice’s 1/6 if you know what you are doing. Küg is a redesign of the dice function of generating a random number from 1 to 6. The exception is that the user does not need to throw Küg, but a small ball that runs through it to reach one of six gates in the design. Each gate has a number from 1 to 6 and the chance for the ball to reach each gate is 1/6.
It must be noted that One of the oldest known dice games was excavated from a Mesopotamian tomb, dating back to around 24th century BCE (ISBN 978-1-4522-6610-7). The dice has not changed for thousands of years.
In the Küg design,the ball is thrown in the center hole, it falls on a tiny platform inside the moving bell and rolls out of six axi-symmetric openings in the bell, and finally lands on the bottom platform and stops at a gate.( In the above picture the gate Roman numbers II ,III and IV are shown) . The ball trajectory is shown in the section view below.
The bell at the center of Küg is not made for esthetic design only, but also for function. If Küg is placed on a tilted table of up to 10 degrees, due to the force of gravity, the bell adjusts and aligns perfectly vertical to keep the chances of all gates equal at 1/6.
The above picture is a first 3D printed prototype to allow the testing and improvement of the design function.
