It’s been a while since I reviewed an app, but I’ve been playing this game for ages. SumSudoku is Sudoku, but with an added requirement. Throughout the 9-square grid are shapes, generally between 2 and 5 squares, that have a total the numbers within have to equal.
The result is a more relaxed (in my opinion) Sudoku. The “sum” areas give you extra hints to complete the puzzle. It’s not as mindless as an idle game, but it’s good for eating up some time.
While there are only a few puzzles available for free (30 each for easy, medium, and hard), you do get a free puzzle each Friday, and you can easily replay puzzles. New puzzle packs are inexpensive, and, best of all, there are no ads!
Ad-free games are few and far between these days, so finding something I can play while listening to music or watching YouTube videos can be difficult. SumSudoku is good for both of those. If you like sudoku, give SumSudoku a try.
