A wooden box with a restricted opening on top and six pieces in 2 different sizes. Can you put all pieces into the box? This puzzle was invented by Dr. Volker Latussek (Germany) and was planned as IPP-40 exchange puzzle for Jerusalem. Made by Yavuz Demirhan.

2019Designed By Klass Jan DamstraProduced by Wood“This pinwheel sort of frame contain four pieces that are two matching pairs. Dissasemble and reassemble the pieces. These pieces move about within the frame quite freely despite the rather close tolerance of the frame to the pieces. I was afraid there may be some unintended solutions but I was not able to find any. Not terribly difficult but a pretty good challenge that seems easier than it really is!”Moves - 11.8.6.4

Ray Stanton wrote about it:"This puzzle is the fourth in the “Slideways” series, and may be the most complex one yet. It is called the “Quad” because it appears to be the intersection of four pieces along each of the three axes, but appearances can be deceiving. As expected, the design is based on the same coordinated motion principle, but in a new and unique way. The solving movement is unusually complex and interesting. You can expect to hear a few “Ohhs” and “Ahhs” when this p...

Another of Ken Irvine's clever designs is this Rotational Cube (well not really a cube) The 3x4x4 Puzzle has a rather difficult to discover assembly. No many moves but still a good challenge I think. I spent several evenings trying to put my copy together before I was forced to break down and ask Ken for the solution so that could get back to making them! Made from exotic hardwoods including Bolivian Rosewood, Maple, Paduak, Movingui and Maple. Your copy may vary from the photo.

Here we have a close relative to Little Kenny, Ken's Little Bruce! While this design is easier than Little Kenny, the assembly may give you a challenge. i think it is fun and the perfect companion to Little Kenny. This would be a great introduction if you are new to TICs. It's easy enough for the first time TIC solver!

Schoolbus by Alfons Eyckmans. The puzzle is very tight. Some of the pieces are hard to move and you need to use force.
