Václav Obšívac (known as Vinco to his friends) has been designing and making puzzles in his own workshop in Frenštát pod Rahoštem in the eastern part of the Czech Republic in north Moravia since 2001. In that year he was a participant at the World Puzzle Championships in Brno in Czech Republic.

Many of Vinco'sdesigns involve very complex pieces created by glueing a series of shapes together. To create these puzzles Vinco collects many trees in his local area including acacia, ash, beech, cherry, elm, larch, maple, oak, pear, plum and walnut. The puzzles are unsealed showcasing the natural colour and texture of the timber.

Vinco is seen here with a very large puzzle he made, he says that even knowing the solution, and with many friends helping out, it took three hours to put together.

Four puzzles in a set to make four different shaped polyhedra. All the puzzles are difficult to assemble. Each puzzle is individually boxed with it's own solution. Good value at under $9 each!

Roof Vinco 6 pieces 4/5 The pieces of this puzzle are constructed from elements that are either a single diagonal 1/2 cube or two diagonal 1/2 cubes joined. The final triangular prism shape is Vinco's Roof - two diagonal 1/2 cubes joined.

Cuboid 1 8 pieces 4/5 Vinco first decided to make a cube with these pieces but then changed the shape to a cuboid or a rectangular prism (looking like a flattened cube!). Each piece is constrcuted from a series a triangular elements. Three Wedges 8 pieces 5/5 Each piece is designed with three elements. One square prism and one square prism cut diagonally to make 2 triangular prisms. All eight pieces are glued differently to create eight different pieces. The final shape is a solid cube.

Octagon AC 8 pieces 4/5 All the pieces of the puzzle are constructed from elements using just two different measurements. A = length of the short side C = the length of the diagonal side The final shape is an octagonal prism.

Difficulty 5+/5 It's difficult to know if this puzzle should be called a two piece or a four piece puzzle. But it's definitely two; even though it looks like a couple of pieces from other Vinco puzzles have got tangled together... (see one of the pieces below) With these two pieces it is possible to lock them together and make a solid, symmetrical shape.

Difficulty 5+/5 You may try 3 (Tri) challenges using the mathematically complete set of 4 different woods on each of 6 pieces which look a bit like bicycle wheels. 1. Uni-Cycle. Simply form a cube (not too difficult) 2. Bi-Cycle. Each corner of the cube must be one single colour (a bit trickier) 3. Tri-Cycle. The cube must have no identical colour touching anywhere, not even diagonally or on an edge (a lot more though required to do this one)

Difficulty 5/5 Diagra - "The puzzle that keeps you up all night" The goal is to make a cube, and the other nine shapes, from the 8 pieces of the puzzle. The shapes are amazingly complex - even for Vinco! Vinco has also now added two additional challenges to be made with co-ordinated motion.

Difficulty 4/5 The puzzle is to take the box apart and get the wooden ball out. There are three identical pieces. Beware, if you take it completely apart you will have to get it back together again.

Difficulty 5/5+ The puzzle is to assemble the six differently shaped pieces into this very complex interlocking burr. This puzzle is one of the hardest that Vinco has ever invented and because of the way it has to be assembled it is not possible to solve this puzzle using a computer program.

The puzzle is to take the four pieces of the puzzle apart; putting them back together will be even harder to do.

The shape is symmetrical in length of it’s diagonal axis but there are two different sized sides.You end up with this shape that looks a bit like an out of square cube.A Crazy Cube! A Cube after it’s been to a party!

The stocks of these new coordinated motion puzzles are very limited and we do not know if Vinco will be making more of these particular puzzles in the future.

Difficulty 5+/5 Xcruci8 may Xasper8, Xulcer8 or Xhilar8!

Your challenge is to assemble the 8 pieces into the symmetrical cross shape. It's packaged in it's unsolved form and even comes with a solution to put it back in it's box unsolved. Now that's a hard puzzle! Don't worry, just like all Vinco's puzzles it also comes with a solution to solve it too.

Difficulty 5/5 The challenge is take the four piece puzzle apart. If you manage that then putting it back together will surely be even harder. The fit is so precise that even identifying the four separate pieces is a challenge in itself.

The puzzle has four different but very complex pieces that go together in a very precise fit to form the beautiful checkered pattern double cone shape. The puzzle starts out as a cube before Vinco turns it into the bicone. Can you see it? It's actually easier to visualise when it's in it's cube box.
