Serious sudoku. Pure logic, explained hints, no ads ever.
About the game
This is sudoku for people who take it seriously. An exact solver has proven that every puzzle has exactly one solution, and you can always finish one by logic alone, never by guessing. The hints explain the reasoning instead of just giving you the number: first where to look, then the pattern, then the conclusion, across more than thirty named techniques. For the commute, your progress runs along a little train line.
