Mini Sudoku practice: endless 6×6 puzzles

Endless Mini Sudoku practice

1,900 puzzles, served in order per difficulty so you can share a game number with a friend and race. Easy has 12 to 17 givens and every step is "this cell has one option". Medium is about the level of a hand-made daily: around 10 givens and a few "where does the 4 go in this row" scans. Hard has 8 to 11 givens and needs many scans. Expert needs pencil marks: naked pairs, pointing, sometimes an X-wing. Unlimited games don't touch your daily streak.
