Al Packino

Design

Ronald Kint-Bruynseels, 2003, Belgium.

File

AlPackino.xmpuzzle

Remarks

This puzzle shows how to properly make packing puzzles. You always should include the box as a piece so that the program can also check if the pieces can be moved into or out of the box. You can also see how to handle multipieces. When looking at the solution it is useful to display the box as a wire frame. This can be done by clicking at the blue rectangle at the lower end of the tools. The rectangle with the text ``S1-Box'' in it.

All Solid 6-Piece Burrs

File

SolidSixPieceBurr.xmpuzzle

Remarks

This file uses the piece range feature and the solutions contains all solid 6-piece burrs. This is done by having all notchable pieces in the problem and having a 0-6 range for all of them. Now each of the pieces may be between 0 and 6 times in the solutions. If you want to get the well known 314 solutions you have to include the mirror solutions.

Ball Room

Design

Stewart Coffin, #197-A, USA

File

BallRoom.xmpuzzle

Remarks

This puzzle shows off the sphere spacegrid. It also demonstrates that is is possible and useful to include more than one problem within one file.

Bermuda

Design

Bill Cutler, 1992, USA

File

Bermuda.xmpuzzle

Remarks

This puzzle demonstrates the triangle space grid. You can see that you can stack many layers on top of each other.

MINE's CUBE in CAGE

Design

Mineyuki Uyematsu, 2002, Japan.

File

CubeInCage.xmpuzzle

Remarks

This file contains MINE's CUBE in CAGE 333, cube g. This puzzle demonstrates how to use the grouping capabilities. The puzzle contains 3 interlocked pieces that construct a cage. These pieces move but can not be taken apart. It needs to be told to the program that this is intentional. So here you have an example of how to do that.

Dracula's Dental Disaster

Design

Ronald Kint-Bruynseels, 2003, Belgium.

File

DraculasDentalDisaster.xmpuzzle

Remarks

This puzzle demonstrates the use of colour constraints. Halve of the result must be red and the other halve black. You can see the colours if you enable the checkbox in the status line at the bottom right.

Level 98 Burr 'The Pelican'

Design

Dic Sonneveld, 2000, The Netherlands.

File

PelikanBurr.xmpuzzle

Remarks

This is a very high level burr. It takes 98 moves to get the first piece out of the box. This is just a demonstration of what is possible.

12 Piece Separation

Design

Stewart Coffin, USA.

File

12PieceSeparation.xmpuzzle

Remarks

A very nice puzzle that required a lot of shifting to get pieces in and out.

Augmented Second Stellation

Design

Stewart Coffin, USA.

File

AugmentedSecondStellation.xmpuzzle

Remarks

An other puzzle based on the Four Corner puzzle by Stewart where the added units are colourized.

Broken Sticks

Design

Stewart Coffin, USA.

File

BrokenSticks.xmpuzzle

Remarks

This puzzle shows off the rhombic grid. It uses colour to show the pieces that were added to the base pieces of the Four Corner Puzzle. Also note that the result shape is there twice. One is the mirror of the other. There is really no difference except for the shape of the ends of the sticks. They can not be cut completely rectangular that is why there are 2 possible ways and only one has a solution.

Diagonal Cube

Design

Stewart Coffin, USA.

File

DiagonalCube.xmpuzzle

Remarks

Strangely shaped pieces form a cube that disassembles along an unexpected diagonal sliding plane.

Hexsticks

Design

Stewart Coffin, Bill Cutler, USA (both independently).

File

HexSticks.xmpuzzle

Remarks

This is an old classic. It can be seen that the pieces can be assembled in 33 ways, of those only 2 can really be assembled. It can also be seen that the shapes of the sticks can not be modelled correctly. The ends can not be cut straight. But as that doesn't destroy the symmetry of the whole shape it doesn't matter. See Broken Sticks for an example where it does matter.

Permutated Third Stellation

Design

Stewart Coffin, USA.

File

PermutatedThirdStellation.xmpuzzle

Remarks

A puzzle that shows the rhombic grid. The pieces are formed by adding additional pieces to the pieces of the Four Corner puzzle. Those additional pieces are colourized.

Pieces of Eight

Design

Stewart Coffin, USA.

File

PiecesOfEight.xmpuzzle

Remarks

A puzzle with multiple problems.

Prisgon

Design

Markus Götz, Germany.

File

Prisgon.xmpuzzle

Remarks

This was one of the very first higher level puzzles using the triangular grid. It was designed manually without the help of computers. The puzzle design exists in 2 slightly different variations: one with the original box as Markus intended and planned which has level 9.6.4 and the other one with a box as it is sold by Philos which has 'only' level 9.5.1.

4-Piece Tetrahedron

Design

Wayne Daniel, USA.

File

FourPieceTetrahedron.xmpuzzle

Remarks

This is a puzzle using the Tetrahedral-Octahedral Spacegrid.
