Sudoku Fun is a free number puzzle game app based on the popular puzzle game by the same name. Sudoku has been around for quite some time, but the digitization of technology allowed the game to take on a much more convenient form, and this app is an example of that. The object of the game is to fill in the grid of numbers such that each of the nine smaller grids that make the whole grid, as well as the rows and columns, all only contain the digits 1 through 9.

This version of the app is exceptionally easy to use, and it has a sleek, modern interface that is intuitive and sharp. There are five difficulty levels in the game, which include beginner, easy, medium, difficult, and expert. Your games are autosaved when the app closes unexpectedly, and you can use pencil marks on the puzzles to help keep track of your logical tree.

While the game is filled with a wide range of puzzles at each difficulty, there will be more added in time. If you have trouble solving some of the more difficult puzzles, you can use the help function to give you clues about how to solve the puzzle.
