hard difficulty · solo mode

Hard Sudoku in Solo Mode opens in the live game shell.

Hard boards ask for deliberate candidate management, repeated scans, and patient eliminations. The shell opens directly on the puzzle so practice starts immediately.

01

Deeper logic

Expect fewer immediate singles and more candidate-based deductions.

02

Direct play

The URL selects Solo and Hard, then creates the board automatically.

03

Strategy practice

Use pairs, box-line interactions, and careful rescanning without guessing.

How it works

Start from this exact Sudoku state.

  1. Open the route to generate a fresh hard Sudoku immediately.

  2. Tap a cell and enter a number; use notes when more than one candidate remains.

  3. Finish the board, then return home or choose another difficulty for the next game.
