The HARD puzzles are tough but not ridiculously difficult. In order to solve my daily hard puzzle, you're going to need to employ one or more advanced techniques like X Wings, XY Wings, Skyscrapers, Unique Corners, etc. However, you will never need a crazy hard strategy like an XY Chain with a ridiculous number of links... For those of you who thirst for harder puzzles, check out my EXTREME puzzles. At some point, you will need to look for ALTERNATING INFERENCE CHAINS of various links, possibly several of them. If this is your cup of tea, go for it!... These puzzles are not interactive. They were designed to be printed out and solved manually. If you prefer to solve them online, just click on the puzzle or use the link below each puzzle. That link will take you to the same puzzle online at SudokuLovers.
