Samurai SuDoku, Killer Sudoku and more

I believe that after all the puzzles that I’ve created and posted for you, you know that I prefer them difficult.

It seems that there is a belief that the difficulty of Hidoku can only be increased by increasing it’s size. I know for a fact that it’s not true, because some of the Hidoku puzzles that I’ve created are really fiendish.

Anyway, today’s puzzle is a small-but-not-too-easy one. I’d like to hear from you how you rate it’s difficulty.

My first CalcuDoku book can now be purchased on Amazon!

The book contains 200 puzzles ranging in sizes from 5×5 to 9×9.
- 136 puzzles are with all operators, evenly split into the standard five difficulty levels: EASY-COOL-THINKER-BRAIN-IQ, but there are also a couple INSANE
- 64 puzzles are with the (significantly) reduced number of operators, mainly THINKER-BRAIN-IQ

Enjoy!

Today I show you a bigger and more difficult Hidoku puzzle. To make sure you know what you’re solving, here are the (very simple) rules of Hidoku again:

1. It can be played on a square or rectangle of any size
2. Numbers from 1 to the size of the puzzle are used. For example, for 9×9 puzzles, numbers from 1 to 81 are used.
3. First and last numbers are always shown in the puzzle and they’re circled.
4. Now, the main rule: consecutive numbers MUST BE adjacent to each other, horizontally, vertically OR diagonally. Therefore, there is a connected path of consecutive numbers from 1 to 81 (or whatever the size). Your job, of course, is to fill in all the numbers.

Have fun!

I told you there is something special coming today and here it is: my first Hidoku puzzle!

These puzzles have been introduced earlier this year and it seems they’re catching on. They are being published under the name “Hidato” but I will have to use Hidoku.

The rules of Hidoku are very simple:
1. It can be played on a square or rectangle of any size
2. Numbers from 1 to the size of the puzzle are used. For example, for 9×9 puzzles, numbers from 1 to 81 are used.
3. First and last numbers are always shown in the puzzle and they’re circled.
4. Now, the main rule: consecutive numbers MUST BE adjacent to each other, horizontally, vertically OR diagonally. Therefore, there is a connected path of consecutive numbers from 1 to 81 (or whatever the size). Your job, of course, is to fill in all the numbers.

Questions, comments, ideas?

I apologize to all Kakuro fans for not updating the weekly Kakuro puzzles regularly lately. Simply there are too many puzzles that I want to show you!

In fact, there is something very special coming up tomorrow, here, on the main page of my site. I’m not going to reveal anything now – make sure to come back tomorrow and get something brand new!

Anyway, I’ll do my best to update Kakuro puzzles on regular basis from now on. Therefore…

Rules: Solve the puzzle so that the numbers in every horizontal and vertical region add up to the sum indicated for that region. Numbers CAN NOT be repeated in any region.
