New Puzzle "Mirii 4x3"

We have started selling the puzzle Mirii 4x3. This puzzle will be shaped in four intersecting triangles when it's assembled. Puzzles that were based on this shape have been designed by others in times past but they were almost like a geometric object and their pieces didn't interlock much, just touched each other on the edges of triangles and all or most pieces were the same shape.


When Juno designed Mirii 4x3, he gave himself a task to design every piece which could connect and interlock in an elaborate way and he aimed to make each piece have a different shape. Then, he made a prototype using pine timber. After he made the prototype, he made up his mind to make puzzles with three different timbers. The timbers he used were Silver Ash (citrus family tree), Jarrah and Blackbean. These are all representative trees in Australia.

Mirii 4x3 is a difficult puzzle. The colour of the pieces can be a hint to solve it but the angles and the direction of crossing pieces of this puzzle are not seen in everyday life. So, you may be confused when you assemble Mirii 4x3 with which direction should make it up from where. However, it is well worth assembling. After you assemble it, you will see a beautiful puzzle that looks like a star. So, I think puzzle lovers would be satisfied with solving Mirii 4x3. This puzzle can be assembled by yourself (which means it can be assembled with two hands) but the surface of the piece is smooth and slippery, so it would be easier to use rubber bands for supporting it temporarily.


You may wonder what the meaning of "Mirii" is. I picked up this word from an Aboriginal dictionary. There are so many Aboriginal languages in Australia and this is from one of the Aboriginal languages and means star. It looked like a star to me, what do you think?

I hope you will pick up the puzzle that looks like a star as one of your Christmas ornaments at home.


Happy puzzling!

Accept multi-currency payment

There is good news for our customers!

We recently changed our online shop to accept multiple currencies. We run our business in Australia but most of our orders come from overseas. For the convenience of our overseas customers, the prices listed in our shop now show the customer's local currency and we have got rid of the previous foreign exchange charges.

Other than Australian dollars, we can now accept US dollars, Canadian Dollars, Euros, British pounds, Japanese yen, and Chinese yuan. When you visit our online shop, the site will automatically indicate your local currency but you are also able to choose your preferred currency by clicking on the currency on the top left-hand side of the web page.

The original prices of our products are set up in Australian dollars. The foreign exchange rate will be calculated once a day automatically and, when you pay, there is no exchange difference, so you simply pay the price indicated.

Up until now, we had only been accepting only Australian dollars, so customers had to pay the foreign exchange fee, but from now on, Pluredro shop will pay the foreign exchange charges, saving our customers about 3% from each payment. Isn't that good news?

We will continue to improve Pluredro shop to create a site that is simple and easy to use for visitors.

We look forward to you visiting our shop.

The new puzzle Reza 4-4 is on sale!

We have started selling one of the polyhedral puzzle series, Reza 4-4. Juno has made two polyhedral puzzles before; Reza 12-20 (Reza 12-20 were already sold out) and Reza 6-8, and Reza 4-4 is the smallest of the Reza family. There are three kinds of compounds of two regular polyhedra and now the Reza family covers all three.


Juno makes jigs every time he makes puzzles and this time he made five jigs just for this puzzle. When he made the jigs, he paid much attention to the orientation of the puzzle pieces placed on to the sled type jigs to minimize the chance of chipping off puzzle pieces.


The order to make checkouts was also important. He also considered the chirality of the assembled shape of the puzzle, right-handed or left-handed to match the leaning direction of the saw blade on the table saw because one chirality is more prone to chip outs compared to the others.


Polyhedral shaped puzzles sometimes become unstable and non self- sustaining when those are assembled. The puzzle pieces tend to come apart by the explosion type movement or coordinated motion. Reza 4-4 was the most difficult one to design the puzzle to be self-sustaining among the Reza family.


It is optional to make most consisting puzzle pieces identical in shape to make the assembled puzzle stable but he doesn't want to take that option because it spoils the fun of puzzles. He made the shapes of all the pieces of Reza 4-4 different and it gives you more fun to play with.

Reza 4-4 is now on sale.
