Like other reviews, I agree that there are far too few free sudoku puzzles to play. 10 free? I can go online and get 600 free then generate another 600, 600 times, for free. My main gripe with this in particular is actually just that all of the hard ones are too easy. I actually finished the "extreme" ones faster than the medium ones. Took less than an hour of my time to get through all of the basic sudoku, so if you are looking for something to sink some time into, this is probably not the one for you. I will say that this is a good introduction to other more interesting sudoku puzzles, and at least you don't have to deal with ads.

Ultimate Sudoku Collection is a free-to-play puzzle game developed and published by Stanley Lam that aims to be a comprehensive destination for Sudoku enthusiasts. Rather than presenting only the traditional version of the famous number puzzle, the game expands the concept with a large assortment of Sudoku variations, difficulty settings, and additional puzzle packs. It is a title designed specifically for players who enjoy logical deduction and methodical problem-solving, offering an enormous amount of content centered around one of the most enduring puzzle formats ever created. At its heart, the game remains faithful to the classic Sudoku formula. Players are tasked with filling grids according to strict numerical rules, ensuring that numbers do not repeat within rows, columns, or designated regions. The elegance of Sudoku has always been its ability to generate challenging problems from simple rules, and Ultimate Sudoku Collection successfully preserves that appeal. Every completed puzzle feels earned because success depends entirely on logic, observation, and careful analysis rather than luck or random chance. What elevates the experience beyond a standard Sudoku application …
