A couple of thoughts on the site.
1. I wish it would auto clear same number notes in a zone (and associated row and column) when you have entered a number.
2. The solver is neat. I ran it after each game, and in each one it referenced one or more X wings or XY wings at some point, but I didn't have to use them to solve the game?? That seemed odd.
I am assuming that lots of eliminations we make by looking at the board can also be logically solved in a different way by a program, and either method can lead you to the same result.
I do like the puzzles that require you to use at least one advanced technique to solve. Some of those XY wings are so hard to see, even when you are staring right at them...lol
If anyone has some tough games from this site then maybe post the number.
