Sudoku 1024

Real Sudoku for real solvers. Easy to unwind, Hard for a real test, Diabolic to push yourself. Clean design, no mid-puzzle ads, no penalties — fully offline.

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.
