A clean, distraction-free Sudoku puzzle app for Android, built for players who want a genuine logic challenge — not a lucky guess. Every puzzle is generated using real human solving techniques and verified to have exactly one solution reachable through pure deduction, so what you're solving is always fair.
Most Sudoku apps just remove random numbers from a solved grid. eSudoku doesn't.
Undo, erase, pencil-mark notes, and a built-in hint system — everything a serious solver expects on the board.
One slip doesn't end your game. Mistake limits scale with difficulty, so the challenge stays fair, not punishing.
Every puzzle generates entirely on your device. No sign-in, no internet connection required to play.
A fresh puzzle every day, with streak tracking to keep you coming back.
Complete rotating objectives for bonus XP on top of your regular puzzle rewards.
Unlock achievements and board themes as you level up. Sign in with Google Play Games to sync progress and compete.
From your very first puzzle to a real test of advanced technique.
When you're ready for something longer.
The challenge rises gradually the whole way — from a gentle start through to an endless run of Expert, Master, and Grandmaster boards for players who never want it to end.
Unlock a new look as you level up.
Optional ads support the free tier. Upgrade any time.
