Reviews for Expert Sudoku
Alaska Surveyor
Great Sudoku Game
What a great game! At first I couldn't solve a single one. I studied Peter Gordon's book and now I cruise--never have to guess. My only suggestion is that there be an "undo" option. Many thanks to you who created this ap. 9/3/21 After all this time I’m still enjoying this great Sudoku app. Every game has one and only one solution, and no guessing is required. My only suggestion is that there be an option to cancel the “Reset” function. It’s too easy to press accidentally. Holy cow! I’ve been playing this game almost every day for all these many years. 2026 is here—I’m no longer an Alaskan surveyor and I’m nearly 83 years old!This game has given me years of pleasure and it’s helping to keep me sharp.
