How it works
Eighteen balls, one loop, six hinges.
- 01
Six hinged segments
Each segment contains two colour-coded tunnels and three coloured balls.
- 02
One continuous loop
As the hinges articulate, tunnels align to form a continuous loop; eighteen balls circulate and can be shifted.
- 03
Restore the colours
The puzzle quickly becomes scrambled; the objective is to return each coloured ball to a tunnel of the same colour.
