 Post subject: New 333 demountable, hollow globe puzzle from France

Being on holiday in France in the past weeks, I found a new puzzle.
It is a 3x3x3 demountable, globe puzzle that can also be used as a coin safe.

The puzzle is fully hollow, the diameter is 102 mm.
Basically there are 3 types of pieces (center, edge, corner) that slide along rails at the edges of the pieces.
However, to allow the full assembly of the puzzle, the sliding edges of the ‘final’ center top piece are slightly changed (smaller). This also goes for the 4 adjacent ‘edge pieces’. So, in practice there are 5 different types of pieces (6 when also counting the edge piece with the coin opening).

The puzzle is very well designed and made, which e.g. can be observed from small openings/notches halfway the edges of the ‘edge’ and ‘center’ pieces which allow a nice alignment of the pieces.

The puzzle can also be assembled without the center pieces, showing the hollow structure and giving an appearance similar to a void cube ball.
However, the 4 ‘edge’ pieces in any equator plane are not connected. So, such a ‘void’ puzzle will not really turn nicely.
Similarly, it would in principle be possible to assemble the puzzle without the 8 triangular ‘corner’ pieces resulting in a different kind of void ball. However, the holding between the edge pieces and the center pieces is rather loose which makes such a structure impractical.
In fact the corner pieces are rather essential in keeping the puzzle together well.

Of course one can not expect speedcubing quality but the puzzle turns nicely and, as mentioned above, the pieces easily position into the correct spots.

Hi Geert,

This looks like the "Bank Sphere" from Hanayama:

Can it be taken apart when solved, like the Gift Cube?

Oskar,

Indeed, in the solved state it is possible to remove the top piece. This is due to the small notches in the top piece in combination with the smaller rims in the adjacent edge pieces. However, unlike your gift cube, only one single center piece can be removed.

After removing the top piece and e.g. turning the face on the right by 45 degrees, it will not be possible to replace the top piece.
So, it would also not have been possible to remove the top piece in that position.

There are 4 edge pieces for which one of the short sides have a reduced rim. Any random sequence of these 4 edge pieces will allow the top piece to be removed.

It looks to me like a piggy-bank that needs to be solved to be opened.
