After a few weekends without any special puzzles, now I present you with another Gattai-4 non-consecutive Sudoku puzzle. This time, it’s a (somewhat forgotten) Butterfly Sudoku variation. The 4 sub-puzzles heavily overlap, so be careful!

Non-consecutive Butterfly (Gattai-4) Sudoku for Saturday, May 10, 2008. Difficulty: Brain

Rules: Solve the puzzle so that any two horizontally or vertically adjacent cells DO NOT contain two consecutive numbers (1 and 2, 2 and 3 and so on to 8 and 9). All other standard overlapping Sudoku rules apply.

Well, it’ time to revive the “Daily Sudoku” page.

First of all, that page has been renamed to “(Non)consecutive”. Since this variation of Sudoku puzzles has proven to be more popular than odd/even and greater/less than, I have decided to give you one such puzzle every day, Monday to Friday. Hardest puzzles (IQ/Insane) will be posted Mondays and easiest puzzles will be posted on Fridays, to balance out the difficulty of Daily Killer Sudoku puzzles.

I hope you will enjoy these puzzles too!

How many Sudoku variants are there? I don’t know. To calculate, you’d have to multiply the number of overlapping types with the number of variants that impose additional constraints on each puzzle. I produce puzzles with 5 different constraints: Killer, Odd/Even, Greater/Less than, Consecutive, and Non-Consecutive. But then again, you can put an “X” on each of those, so you’d have to double the number. Some creators even produce puzzles that can have more than one of these constraints. Then there are jigsaw sudoku puzzles… Well, I’ll leave it up to you to count all different variants, while I’m presenting you another one for the very first time: Clueless Consecutive Sudoku puzzle!

In this puzzle, there are 9 Sudoku puzzles with no overlapping regions! If you attempt to solve them individually - you won’t get far.

Here is where the “clueless” part comes in: in all of those 9 puzzles, the center nonet is empty. As you plug in your numbers, center nonets (shaded in grey) start filling up. The trick is that those 9 center nonets, put together, also constitute a valid Sudoku puzzle. So, when you run out of ideas, start working on the 10th puzzle and it will give you enough information to solve the whole lot. Those 10 puzzles together have, of course, a single solution.

Important: Consecutive numbers are marked as usual with pipe symbols “|”. Pay attention to lines that separate sub-puzzles: consecutive/non-consecutive cells are marked there, too. However, in the 10th puzzle that consists of 9 nonets from other 9 puzzles, the only (non)consecutive cells are those that are already marked. There is no information given about consecutiveness of the cells between those 9 nonets. I hope you see what I mean.

If you have any doubts about the rules for this puzzle, please ask here or in the forum before you lose a lot of time attempting to solve this puzzle.

Someone complained and asked for more new variants and specifically for cons/non-cons puzzles. So here it is - first ever Consecutive Butterfly (4 in 1) Sudoku puzzle.

“Pipes” (”|” symbols) between cells mean that those cells must contain consecutive numbers. If there is no pipe - those cells can’t contain consecutive numbers. This second part of the rule is very important but also easy to forget. All this, of course, in “Butterfly” format, meaning there are 4 puzzles that heavily overlap.

Good luck and enjoy!

To be honest, I haven’t kept track of all the different sudoku variants that I have posted and which ones I never posted, but I think that this is the first Consecutive TwoDoku X sudoku puzzle ever. I will check in my archive when I find some time to see if this is true or not.

Anyway, “pipes” (”|” symbols) between cells mean that those cells must contain consecutive numbers. If there is no pipe - those cells can’t contain consecutive numbers. This second part of the rule is very important but also easy to forget.

Since the focus is now on Samurai Sudoku puzzles , I’d like to introduce yet another variant of this overlapping 5-in-1 Sudoku puzzles: Consecutive Samurai Sudoku!

As far as I know, this is one of a kind puzzle - if you have already seen it elsewhere please do let me know.

So, “pipes” (”|” symbols) between cells mean that those cells must contain consecutive numbers. If there is no pipe - those cells can’t contain consecutive numbers. This second part of the rule is very important but also easy to forget.

I’d like to hear your thoughts on how difficult you find these puzzles. There are only 12 starting clues, so it might seem too difficult, but only the very basic techniques are required. Once you get going, it becomes a whole lot easier. Good luck and enjoy!
