PLAY YOUR WAY
──────────────────────────
• Four difficulty levels: Easy, Medium, Hard, and Extreme
• Note-taking mode for tracking your possibilities
• Instant error highlighting so you always know where you stand
• Hints and auto-reveal power-ups for when you're truly stuck

BEAUTIFUL THEMES
──────────────────────────
Start with Crystal Light — a crisp, daylight-friendly design. Unlock Dark Aurora and Ember by reaching milestones, or browse the store for Midnight, Ocean, Forest, Neon, and more. Every theme is carefully crafted, not just a palette swap.

──────────────────────────
KIDS MODE
──────────────────────────
Swap numbers for emoji, animals, fruits, space icons, and more. Color mode replaces symbols with colored circles for the youngest players. All symbol sets work in note-taking mode too.

MILESTONE REWARDS
──────────────────────────
15 milestones track your progress and reward you for playing well — not just playing often. Earn tokens, unlock themes, and collect symbol sets just by enjoying the game.

SMALL DETAILS THAT MATTER
──────────────────────────
• Completed rows and columns flash and chime
• Win fanfare when you finish a puzzle
• Confetti on victory
• Your game is saved automatically if you close mid-solve
• Stats per difficulty: win rate, best time, streaks

Fun Sudoku is free to play. Optional purchases include token packs, premium themes, and a one-time Remove Ads upgrade.
