## What is Sudoku 1024?

Most Sudoku apps hold your hand. Sudoku 1024 respects your brain.

The puzzles here are genuinely hard. Easy is a relaxed solve to unwind, Medium steps it up, Hard is a real test of technique, and Diabolic is for when you truly want to challenge yourself. Every grid is handcrafted and solvable by pure logic. No guessing, ever.

WHY PLAYERS SWITCH
• Genuinely hard puzzles — Easy is a relaxed solve, Hard is the real deal, and Diabolic is for when you want to push yourself. Four levels: Easy, Medium, Hard, and Diabolic.
• Clean, distraction-free design — sharp typography, a calm board, and Light / Dark / System themes. Nothing between you and the grid.
• No penalties, no pressure — no "3 mistakes and you lose," no forced timer, no streak to protect. Make a move, undo it, take all the time you want.
• Ads that stay out of your way — yes, there are ads so we can keep building the app, but never a video dropped into the middle of your puzzle. We hate those too.

FEATURES
• Four difficulty levels, from a real challenge to Diabolic
• Fast Mode — automatically filters the valid numbers for each cell
• Pencil marks for working out tricky cells
• Cell coloring to visually group your reasoning
• Unlimited undo, plus optional hints when you're truly stuck
• Daily streaks and per-difficulty stats to track your progress
• Game history with mini grid previews
• Light, Dark, and System themes — your choice is remembered
• Fully offline — no Wi-Fi required
• Localized in 12+ languages

PREMIUM (optional)
A one-time purchase unlocks unlimited Fast Mode and removes all ads. No subscriptions, ever.

PRIVACY
Your games stay on your device. Sudoku 1024 follows Apple's privacy guidelines and clearly declares any data shared with analytics or ad partners.

For players who want a real logical challenge, a beautiful board, and zero nonsense.
