3 stars: Overall it's okay. However, my second puzzle in I reached a valid conclusion and the game said it was incorrect; it just happened to be that I ended with only two rows with matching pairs remaining. Both my answer and the game's \
5 stars: Finished one puzzle and like it very much! And I still like the challenge and I think this game would help kids with math. Expressed this new idea on 3/20/2021
4 stars: Love this game but every two days I get a black screen which doesn't go away. I am going to uninstall it. EDIT I am unable to screenshot as all that you would see would be a black screen (see above). I have an LG K42 which uses android. As I have uninstalled the app (permanently) I cannot contact you via the app.
3 stars: Good variation of sudoku. I have yet to win one of the events. They are too short for me. I always run out of time before completing all of the puzzles. Can you please make them a couple days longer?
5 stars: I've just started but I can say it makes your brain work. I enjoyed it. I'm not great at Sudoku, but this app. made me feel like a champion.😁😂
5 stars: This is cool and not bad, I love it so much; it's way better than the classic sudoku and it's my first time playing it. I should play it everyday!
4 stars: Ex cellant! Have played the paper version of killer where yo have to either write down every permutation of all numbers In twos, threes, fours etc or wirk them out individually each time .Exhausting for a gentleman ...
