## What is Iekes Sudoku?

Train your brain with classic Sudoku — clean, ad-free, and made for the joy of logic.

Iekes Sudoku is a beautifully simple Sudoku game with everything you need to play, learn, and improve.

KEY FEATURES
• Four difficulty levels — Easy, Medium, Hard, Expert. Every puzzle is uniquely solvable.
• Educational hints that explain the WHY — not just what to fill in. Learn techniques like Naked Singles and Hidden Singles as you play, with plain-English explanations and visual highlights showing the cells that prove the answer.
• Pencil notes for working out candidates. Turn on Notes mode and drag across multiple cells to mark them all at once.
• Real-time correctness feedback. Wrong answers turn red. You have 3 mistakes per game.
• Smart highlights. Selected cells highlight their row, column, and 3×3 box. Tap any number to find every instance on the board.
• Score system. Faster correct entries earn more points. Hints and mistakes deduct.
• Statistics. Track games started, win rate, perfect wins, best score (today, this week, this month, all-time), best time, average time, and your current and best streak.
• 100% private. No tracking. No ads. No data leaves your device.

WHY IEKES SUDOKU
Every puzzle is generated fresh with a unique solution. The hint system isn't just a "fill it in" button — it teaches Sudoku techniques with explanations and visual evidence so you understand the reasoning, not just the answer.

Built for iPhone and iPad. iOS 18+. Light and dark mode supported.

Made with care. No ads, no tracking, no in-app purchases.
