I posted another classic Sudoku that requires Swordfish/X-Wing solving technique. You should practice this technique because at some stage I might post a Killer Sudoku that will require you to use this technique to solve the puzzle. Maybe. 🙂 Of course I also posted another Killer – it’s a Brain X. Have fun.
