My first Nurikabe puzzle (a difficult one)
Another addition to my portfolio of various number/logic puzzles are Nurikabe puzzles. I think these puzzles are being undeservedly somewhat neglected in the puzzle world and I intend to change that. The number of solving techniques and approaches that can be found in Nurikabe puzzles far exceeds any other puzzle type. For me it was […]

In order to avoid any further confusion with KenKen(R) and KenDoku(TM) trademarks of Nextoy, LLC, I have changed the name of these puzzles to CalcuDoku. This name is also used by other publishers but it is not trademarked.

Sudoku Straights
It’s only Wednesday, but I decided to present you with another Sudoku Straights puzzle. Remember that they are shown every Friday on the Daily Sudoku variants page. The rules: 1. Use numbers 1-9. Numbers cannot be repeated in rows/columns. 2. There are no nonets (3×3 boxes) like in other Sudoku puzzles. 3. Black cells do […]
