Daily Consecutive/Non-consecutive puzzles

By djape | Published: February 20, 2007

By djape | Published: September 27, 2006
Well, folks, one year has passed since I posted my first INSANE Killer Sudoku puzzle. Although it wasn’t “perfect” (it contains singleton cages), most probably this site wouldn’t become popular if it hadn’t been for that puzzle.

A quick reminder – this breed of overlapping sudoku puzzles was suggested by udosuk and implemented by myself. There are 4 “classic” 9×9 Killer Sudoku puzzles inside this one. They all overlap and they all must be solved according […]
