A modern Sudoku game built with Godot 4
A Sudoku game for Android built in Godot 4: a fork of an open-source base, extended with note mode, a smart numpad, a multi-tier hint system and difficulty levels, then shipped to the Play Store.



A backtracking generator creates unique, valid puzzles with exactly one solution, from Simple to Master difficulty.
Pencil marks in a sub-grid per cell, and number buttons that disable once all nine of a digit are placed.
Random hints plus "Hardest Cell" logic, alongside live row, column, box and matching-number highlighting.
