Sudoku Club: Explained Hints

Stuck on a sudoku? Most hints just drop a digit into a cell. Sudoku Club tells you which technique applies, highlights the cells involved and explains why the move is forced, so next time you can spot it yourself. Hints that teach • Every hint is one sound logical step • The technique is named, from naked and hidden singles up to X-Wing and Y-Wing • The cells behind the reasoning are highlighted on the board Six honest difficulty levels Beginner, Easy, Medium, Hard, Expert and Extreme. Each puzzle is graded by the hardest technique it really needs, and every puzzle has exactly one solution. A puzzle for every day The daily puzzle is the same for every player and gets harder through the week, from Monday's Beginner to Sunday's Extreme. A monthly challenge gives you a longer goal to work toward. Learn at your own pace 40 technique lessons in five courses take you from your first single to X-Wings and Y-Wings.
