What's new in Sudoception.

New

• One puzzle a day, the same grid for everyone in the world at midnight, your time. Gentle on Monday, easy, moderate, tricky, hard, fiendish — and diabolical on Sunday
• Every puzzle has exactly one solution and never needs a guess
• Hints that teach — every hint is the next logical technique, named. Never a random reveal
• Pencil marks, undo, an optional mistake check, and a timer that pauses when you look away
• Streaks. Solve it on the day and it grows; miss a day and it shows
• Four Game Center leaderboards — Today's Fastest, Points in a 30-day round, all-time Points and Longest Streak — plus achievements. No account to make; only on-day solves count on the daily board
• Insights: solve times against par, the techniques that stall you most, your best days, mistake and hint habits, personal bests per grade
• A share card — your time, your grade, your mistakes as a 3×3 of squares
• Made for the Mac: play entirely from the keyboard — arrows, digits, pencil mode, undo, hint — with a menu-bar extra that counts down to the next puzzle
• Widgets on every platform, Shortcuts ("Play today's Sudoception", "What's my streak?"), and a single optional daily reminder on iPhone and iPad
• Your history syncs through your own iCloud, and exports as JSON whenever you like. No account, no ads, no tracking
