I didn't try to do them without the X. I mainly did them to practice Y-Wing hunting. Next time I do some of the easy puzzles in the book I'll try and overlook the X and see what happens. Hmmmm.

Hands up how many people immediately found the 7 in the middle region and started solving the 7s? I like the X-factor because it adds new ways to solve a puzzle even if you don't need the X. I enjoyed finding the Y-wing made of 8s in the X section and that wouldn't have happened without the X constraint. Also, the X made a few X-wings in the lower regions that were fun to find, I usually don't get DELL puzzle books (although I like their cross sums / kakuro), but I did pick up an Extreme Sudoku book and do the X-factor sudokus in it when I feel the desire. ***
