QiYi Rainbow Ball (12 Holes, Glow in the Dark)

The luminous version of the rainbow ball. Same puzzle — shift the twelve coloured balls around until each one sits in its matching ring — in a translucent shell that soaks up light during the day and glows once the room goes dark.

Charge it under a lamp for a minute and it holds the glow for a good while. This is the one that ends up next to the bed rather than on the desk.

Note: the shell colour ships at random — blue, green or pink. All three glow the same.
