This is a Sum Skyscraper. Place the digits 1 to 5 once each into every row and column in the grid. Numbers outside the grid provide More >

Following-up yesterday’s Skyscraper puzzles, I thought I’d post a couple of Sum Skyscraper variant puzzles.
Sum Skyscraper 6×6 puzzle
Sum Skyscraper 5×5 puzzle
Sum Skyscraper puzzles are very similar to Skyscraper puzzles, so no number can repeat in any row or column and external ’skyscraper’ clues reveal information about the numbers in the main grid. In 5×5 puzzles More >

Sudoku Non-consecutive-diagonal 9×9 1 puzzleThis is a non-consecutive-diagonal sudoku puzzle. No digit may be diagonally-adjacent to a consecutive digit. But as you can see from the givens, consecutive numbers can be adjacent horizontally or vertically. What you can’t have, for example, is a 1 diagonally next to a 2 because the 1 & 2 are More >

Sudoku Snake 9×9 1 puzzleHere’s something a little different – a consecutive snake sudoku.
Each of the shaded snakes consists of only ‘consecutive’ cells along its length, which means that any two cells joined by a snake must have values with a difference of 1, such as 2&3 or 7&8. So for example the 4-square-long snake More >

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 >

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.
