Suduku Sun

New: adaptive Sudoku that grows with your skill. Large numbers, calm colors, daily streaks, and gentle hints. Relaxing brain training for iPhone and iPad.

Sudoku Sun is a calm, large-print Sudoku puzzle app designed for comfortable play on iPhone and iPad. Whether you are new to number puzzles or a longtime logic game fan, every grid adjusts to your pace so each solve feels just right.

Play unlimited Sudoku puzzles with oversized numbers, a clear board, and a simple tap-to-play number pad. No tiny text. No clutter. Just relaxing brain training you can enjoy at your own speed.

ADAPTIVE SUDOKU THAT GROWS WITH YOU Sudoku Sun watches how you solve (your time, mistakes, and hints), then picks the next puzzle to match your skill. Faster days gently raise the challenge. Tough days ease up. Levels never run out, so you always have a fresh logic puzzle waiting.

LARGE PRINT AND ACCESSIBLE DESIGN Built for easy reading and comfortable tapping. Sudoku Sun supports Dynamic Type, Bold Text, VoiceOver, and Reduce Motion. Every square, button, and number is sized for clarity so you can focus on the puzzle, not the interface.

EASY, MEDIUM, HARD, AND EXPERT Choose your preferred difficulty or let adaptive mode find the sweet spot. Each Sudoku puzzle is uniquely generated with a single correct solution, never the same catalog twice.

GENTLE GAMEPLAY, NO PRESSURE Mistakes are highlighted softly. Wrong numbers clear on their own. Use Notes to pencil in possibilities. Undo a move anytime. Up to three hints per puzzle when you need a nudge. No harsh penalties, only encouragement.

STREAKS, XP, STARS, AND ACHIEVEMENTS Stay motivated with daily streaks, experience points, star ratings, and unlockable achievements. Follow your progress along a blooming garden path as you level up from Sunny Meadow to Summit View.

AUTO-SAVE AND CONTINUE ANYTIME Life happens. Sudoku Sun saves your puzzle automatically so you can close the app and pick up exactly where you left off.

OPTIONAL DAILY REMINDERS Turn on gentle notifications for a daily Sudoku puzzle, streak protection, comeback nudges, and level celebrations. Fully opt-in. At most one friendly reminder per day.

CALM COLORS AND SMOOTH FEEDBACK Soft animations, gentle haptics, and a warm visual style make every session feel peaceful. Challenge mode is available when you want to push yourself.
