4 new Sudoku variants books!

There is a lot of catching up I need to do… it’s busy times for me folks, so stay tuned as more puzzle books get published. Tomorrow I am sending out a newsletter, which is the best way to never miss an update from me.

Anyway… while you were busy following the elections, I worked hard and published 4 new titles, all 4 of them with Sudoku Variants puzzles.

First up is volume 4 of the Sudoku Variations series.

Next is volume 2 of the Multi Sudoku series with LOCO Sudoku puzzles. Totally crazy sudoku stuff!

And finally, two new volumes with irregular sudoku jigsaw puzzles. One is your standard jigsaw sudoku book, while the other is jigsaw sudoku compendium, which means that it contains variations on the irregular sudoku variant puzzles.

Next week, I will be releasing more Killer and Samurai books!

CalcuDoku, Killer and 3-variants books

Hello everyone! It’s been a while… I sent out a newsletter this weekend and in case you haven’t seen (why haven’t you?) I’d like to let you know of the three new titles that have just been released.

The latest one, fresh off the press, is the largest calcudoku book I know of! It contains 1000 CalcuDoku puzzles of all difficulties and in sizes 4×4, 5×5, 6×6, 7×7 and 8×8, 200 of each of them. If you like CalcuDoku puzzles (aka KenKen™, Kendoku™, Opdoku, Mathdoku…) I think this is the best value for your money!

Second book is also a second volume of the Cutting-Edge Sudoku series. The three sudoku variants in this book are the same as before: Flower Sudoku, Outside Sudoku and Consecutive Sudoku.

And last but certainly not the least, is a very special book. It is a new, special, 10th anniversary edition of the “Sudoku K” book, which was published in 2006 and was the first book I ever published worldwide. So… if you would like to be reminded of how the Killer Sudoku puzzles used to be back then, this is the book for you!

More books are coming soon. Make sure to sign up for the newsletter if you want to be informed as soon as they are released!

Three new very special titles!

In case you missed out on the newsletter I sent a few days ago, here is an update on the three new titles I released for Summer 2016.

First up is a new Trigons book, this time with 300 puzzles! You asked for it, so go get it now 🙂 All sorts of new designs and layouts of the trianglons, mostly with 0 to 6, but some of them are of bigger and smaller dimensions, too!

The second book is a very special one – my first book with nothing but Clueless Sudoku puzzles! I’ve published a couple of them in other books, but this is a book of just sudoku puzzles which might leave you clueless – at first. 9+1 grids in each puzzle, so there are many numbers for you to solve!

And finally, another novelty, a book with more Samurai Sudoku puzzles than any other book I know. 500 Sudoku Samurai Gattai-5 puzzles in one book, just like those I publish in The Washington Post and The Washington Express! It’s great value for money, this book!

That’s it for this Summer folks. Have a great one and await new books in the Fall 2016!

Zero Trigons

Hi folks, it’s been a while! What can I say? I’ll try to be more regular with new puzzle updates, but I can’t promise anything. New puzzle books are coming soon, so stay tuned.

Meanwhile, here is a new Trigons puzzle. And it’s first of its kind – it’s a zero trigons! This means that the sum of some trigons is not shown in the puzzle, it is up to you to completely figure them out.

Ok, you might need a crash course in trigons. Here are the Trigons rules:

Let’s repeat all rules of Trigons:

1. For this puzzle, use digits 0 to 5 to solve it.
2. The numbers given in the puzzle represent the sum of the three digits on the sides of the corresponding triangle.
3. Your goal is to fill in the numbers on the sides so that they add up to the given sum for that trigon (triangle).
4. Numbers CAN BE REPEATED a triangle.
5. Each sum combination MUST BE USED EXACTLY ONCE! All triangle sum combinations are given below the grid so when you use one, cross it off.
6. If a trigon shares only one side with the rest of the puzzle, the other two sides of the trigon must be equal, i.e. must be solved using the same number. Such trigons are called “pointed tips“.
7. If a sum is not shown in a triangle, you must figure it out by eliminating all other possibilities. It still MUST BE ONE OF THE SUMS listed below the grid, and of course, the sum combination cannot be repeated.

Does this make the puzzle too difficult? Please share your thoughts.
