About game
Sudoku: Whisper of Digits is classic sudoku with an unusual narrative layer. You discover an archive notebook where every solved grid reveals a new diary line.
Fill cells so digits never repeat in a row, column, or box. 40 levels grow from easy 6×6 grids to expert 9×9 puzzles. Four difficulty tiers: easy, medium, hard, and expert.
Features include any-level selection, sound settings, ad-rewarded hints, progress saving, and leaderboards. Play on the go or at home — one round takes 3 to 15 minutes.
How to play
🎯 Goal — fill every cell with digits 1 to N so no row, column, or box repeats a number.
⚡ Basics — tap a cell, then a digit below. Gray digits are fixed. "Erase" clears a mistake. "Check" validates the grid.
🌍 Story — each win unlocks a diary fragment. Complete all 40 levels for the finale.
▶ Hint — the ▶ button reveals one correct digit after watching an ad (once per level).
⚙ Settings — sound on/off, default difficulty, rules.
📋 Levels — pick any of 40, including completed ones.
