The Cross Puzzle is about as simple to solve as you will find. However, there is a simple principle of Physics involve; and if you don’t twig on to it, try as you may, you’ll never get it apart. That principle is definitely not force. Force can probably be used to take just about any puzzle apart, but in doing so, it’ll also probably wreck the puzzle. The principle used in The Cross Puzzle is also used in other puzzles that have been around for years, taking different forms and made [Read More...]
Dragon Cube is a fascinating little puzzle from the folks over at Gotta Solve It. Invented by their chief mechanical puzzle engineer, Doug Engel, the Dragon Cube is able to transform itself is several different shapes. This was first introduced in 2000 as an exchange puzzle at the 20th IPP, then called Perfect Ring of Eight.
The puzzle is built from wood and painted with eight different colors, producing a very nice visual effect. Although I prefer wooden puzzles, in this particular case I think plastic would have been much more appropriate, since you’re [Read More...]
It’s approaching Christmas as I write this and puzzles make great stocking stuffer. The Dinosaur Egg is what is called a mechanical hand held, burr, or take-apart puzzle. It is marketed by many different companies, usually made of wood, but I suppose it is also made of plastic, or even possibly of metal. It goes by many names such a Dinosaur Egg, Football or Rugby, Mulberry, etc. As to difficulty, it is fairly simple; 1 or 2 out of 5. Some puzzles like this can be difficult to take apart, but this one is unusually easy. [Read More...]
Floor is another unique Packing Puzzle from Jean Claude Constantin. This unusual mosaic is reminiscent of a honeycomb pattern, albeit having pentagons instead of hexagons. The puzzle itself looks like it consists of 19 pieces, but in reality only the inner 7 pieces are removable.
The puzzle is made of three layers of what appears to be plywood. The top of the pieces are very well polished and feel smooth to the touch. Size-wise it’s a small puzzle, measuring only 12 x 10.5cm (4.7″ x 4.1″).
The pieces of the Floor puzzle are also very unusual. Each piece [Read More...]
The Puzzle Dice is a beauty of a puzzle, or more appropriately what you would call a brainteaser. It is essentially a 2 3/4 inch dice that is sliced into 9, same shaped pieces. By slicing the dice this way, the pieces end up with the “spots” scrambled. Obviously, the challenge is to reassemble the dice so that the total number of spots on opposite sides always equal 7; as with the regular dice. The Puzzle Dice is a puzzle that looks easier than it is and therefore if left around just about anyone will [Read More...]
2D Packing Puzzles allow for some of the most creative works in puzzle design. This type of puzzles is so versatile that you can do almost anything you can imagine. A great example of such creative design is Martin Watson’s Digigrams (also called Count on Me!).
Digigrams is comprised of 10 pieces representing the numbers in digital form from 0 thru 9. The goal is simple: just pack them into the provided tray. The solution is neatly packed to make the most out of the available space, due to the unusual shape of the pieces.
The puzzle is [Read More...]
This looks more like an optical illusion object than an actual puzzle. The mesmerizing pattern created by these two loops almost gives a sense of movement. Its designer is none other than Jean Claude Constantin.
The 2 Loops is actually a Packing Puzzle with six pieces. Simply remove the pieces from the tray and pack them up again. It’s deceptively easy, considering the complexity of the two shapes. The puzzle is made from two contrasting wood tones, which gives an impression that only the lighter parts can be removed and the others are part [Read More...]
