What is inside

Everything needed to make a round of Sudoku genuinely comfortable on a phone — not a desktop layout shrunk down to fit.

9

Three board sizes

4×4 for kids, 6×6 for a quick round, and the classic 9×9 — each on easy, medium or hard.

1

Exactly one solution

Puzzles are built with a bitmask backtracking generator and checked for a unique solution before you ever see them. You are never forced to guess.

Pencil marks and undo

A 3×3 notes grid inside every cell, and placing a digit clears that note from every peer cell automatically. Undo remembers 200 moves.

Three lives, three hints

A wrong digit costs a heart and shakes the cell. Three hints are there when a board really will not budge.

Readable at a glance

The selected cell lights up its row, column and box, matching digits are tinted, and every number button shows how many of that digit are left.

Sound you control

Music and effects have separate levels: ten steps up or down, or off entirely. Your choice is remembered on the device.

Resume and records

An unfinished game is saved automatically and comes back with CONTINUE. Best times are kept per board size and difficulty.

Private by design

The game requests no Android permissions, never touches the network and collects nothing. Everything stays on your phone.

Installing, in three steps

This file is distributed outside Google Play, so Android asks for your permission once.

  1. Download the APK with the button at the top of the page.
  2. When you open the file, Android shows an "install from unknown sources" prompt. Tap Settings and allow installs for your browser or file manager.
  3. Go back to the file, tap Install, and play.

If you already installed an older build from a different file and the install fails, remove the old one first — APKs signed with different keys cannot replace each other.
