How to play
The rules in two minutes, then the techniques that take you from easy to expert.
Why these puzzles are good puzzles
Every grid here has exactly one solution. You never need to guess.
We grade each puzzle by the hardest technique it needs, not by how many numbers are given. An easy puzzle only asks for singles. An expert puzzle needs an X-Wing or an XY-Wing at some point.
Mistakes are yours to find. Turn on mistake checking when you want help, leave it off when you want the real thing.
