PLAY YOUR WAY

Three difficulty levels — Easy, Medium, and Hard — so beginners and experts both have a real challenge waiting Pencil-mark notes that clean themselves up: place a number, and matching notes clear automatically across its row, column, and box Undo, erase, and an adjustable mistake limit — play it safe or live dangerously One free hint every day, plus the option to watch a quick ad for more whenever you're stuck A NEW CHALLENGE, EVERY SINGLE DAY Solve a brand-new Daily Challenge puzzle each day, build a streak, and browse your full challenge history on a calendar going back to 2020. Daily challenges save your progress automatically, so you can always pick up where you left off.

SEE YOURSELF IMPROVE Full statistics per difficulty — games played, best and average time, best and average score, and your current and best win streaks — plus a trophy shelf tracking how many daily challenges you've completed each month.

SMART, SATISFYING SCORING Points are awarded based on how hard a placement actually was to deduce, not just for filling a box — so a lucky guess earns less than working out a genuinely tricky cell.
