Quintessential Puzzle Game
Ive been a strong supporter of this game since 2013 now, and its one of my favorite apps out there. Ive loved math and programming since childhood, so logically a game all about logic is a perfect fit for me.
Theres a vast variety of puzzles, totaling over 10,000, and as someone who has completed over 1,500 of them, let me assure you this game is not "broken." Each puzzle really does have only one solution. I can speak from experience that each time I thought I had a solution but it wasnt saying it was solved (and I even went as far as to screenshot a couple of them because I was so bothered that it wasnt solved) I eventually realized that there was indeed something I overlooked.
Overall, if you like sudoku, itd be a crime to not give this game a try, and there are still plenty of other types of puzzles for you non-sudoku-but-logic-loving people out there, too.
