mySudoku: Learn & Play

mySudoku is Sudoku for people who want to get better at it. Every puzzle has exactly one solution and is rated by the solving technique it needs, not by how many clues it shows. Beginner puzzles fall to singles; Expert puzzles need Swordfish, Y-Wing or coloring. You always know what a level asks of you. HINTS THAT TEACH A hint never just fills in a cell. It names the technique first, then shows you where to look, then explains why, and only places the digit if you ask. Hints are limited per level, so they stay a lesson rather than a crutch. LEARN THE TECHNIQUES Twelve techniques, from Naked Single to Simple Coloring, each with an interactive lesson on a real board. Watch the step unfold, try the position yourself, or generate a fresh puzzle that needs exactly that technique. Statistics keeps track of which techniques you spot on your own. DAILY CHALLENGE The same Medium puzzle for everyone, every day, with a calendar of past days, a medal for every solve, a trophy for a complete month and a daily leaderboard. PLAY YOUR WAY • Pencil marks, Snyder notation and candidate colouring in five colours • Cell-first or digit-first input • Highlight matching digits and conflicts, optional auto-check • Relaxed Mode: hide the timer, set your own mistake limit or none at all • Undo, redo, pause, reset • Sounds and haptics, each with its own switch On the Mac: full keyboard control, menu commands, printing, and a menu bar puzzle that is always one click away.
