Consecutive Skyscraper puzzle
It’s been a while since I posted a new puzzle here, what with all the excitement about Sudoku Xtra magazine, so I thought I had better do something about that right now! So to that end, here’s something a little bit unusual – a Consecutive Skyscraper puzzle.
Now Consecutive Skyscraper may sound like a More >

Wrap-around Consecutive Samurai Star puzzle
I seem to be posting more infrequently than I intend, so I thought I’d compensate with a puzzle that would take somewhat longer to complete! Here, then, is a wrap-around consecutive samurai star. All squares with consecutive values (a difference of 1) are marked with white bars, including those at opposite More >

Consecutive 12×12 Sudoku puzzle
After a bit of a break to meet a major book deadline – the non-consecutive part of the title of this posting – I’m back with what seems to be one of the most popular types of puzzle, a Consecutive Sudoku. I wanted something a little bit different, though, so this is More >

Skyscraper Sudoku 8×8 puzzle
Continuing my series of 8×8 Skyscrapers and variants, here’s an 8×8 Sudoku with Skyscraper clues around the edge.
The rules are simple:
Place 1 to 8 in each row, column and 4×2 box
Obey the Skyscraper constraints: each number outside the grid reveals the number of ‘visible’ digits looking along that row/column, where higher digits More >

Skyscraper Shuriken Samurai Sudoku puzzle
I’m glad yesterday’s Shuriken Samurai went down well, so today I’ve upgraded it to a Skyscraper puzzle (following Christine’s request for more Skyscrapers!). This is, I think it’s fair to say, quite a bit harder than the basic Samurai yesterday was – but then any puzzle with a title this hard More >

Wrap-around Consecutive 3-grid 6×6 Samurai Skyscraper puzzle
Another mouthful of a puzzle name, but in essence simply a development of the previous puzzle I posted. This time we still have the wrap-around consecutive-ness, but I’ve extended it to a samurai puzzle and added in skyscraper clues. To keep it reasonable, I’ve reduced the underylying Sudoku size More >

Consecutive Wrap-around Fiendish Sudoku puzzle
Here’s a slight twist on Consecutive Sudoku – I’ve included ‘wrap-around’ consecutive indication, where rows that start and end in consecutive digits have a white bar at the start and end of the row to show this, and similarly for columns. If they’re non-consecutive then there is no white bar. Similarly More >

Skyscraper Sudoku puzzle
It occurs to me that I didn’t get round to posting any ’straightforward’ Skyscraper Sudoku puzzles previously, so I thought I’d rectify that today. Attached is a regular 9×9 Sudoku with the addition of Skyscraper clues around the edge, and no other twists!
For the Skyscraper clues the numbers around the edge represent the More >

Skyscraper 7×7 puzzleSkyscraper 5×5 puzzle
It occurs to me that I haven’t yet posted a regular, vanilla Skyscraper puzzle, so I decided that today was the day to rectify that! The 5×5 puzzle attached is pretty easy – it can be solved in under a minute if you’re on your toes! The 7×7 is nowhere near More >

Samurai Consecutive Sudoku
I thought it would be a nice idea to create a large Consecutive Sudoku for the weekend! And so here one is: a 5-grid Samurai Consecutive Sudoku. As you can see, there are very few givens to start with, so it will hopefully be at least a bit of a challenge! (It shouldn’t More >

This was a lovely puzzle, although as with some of the other combinations, the addition of the consecutive markers meant you didn’t need too many of the skyscraper clues.

Yum!
I had fun doing this one.
I am working on a notation where I check the skyscraper clues (after sharking for 8s and 7s) and if I notice a row/column where all of the buildings have to be in ascending order, I’ll write in the greater than signs between the lines like futoshiki. This also helps when I know there has to be a gap in the order when only 2 boxes are left in the view.
This helped with the pinwheel in the upper left, and I completed the puzzle in such a quick time that I went back to make sure I didn’t make any mistakes with consecutiveness.
I really do like these because it is a change from the usual ones you see in magazines.
