However it doesn’t rotate so one can play and charge at the same time and it crashed 5 times in a row after 30-45 seconds of play on the first Daily I attempted. Sadly unplayable at this time. ### 4/5 — Fun but ads *2026-06-28, version 1.9.1* This is an amazing game and highly addictive. The only thing is there are so many ads. That’s the only problem I have the game. I love a good challenge so this game is great. There are even some holiday puzzles for you to crack. Over all,number sum is an amazing game and I think everyone should try it out. ### 2/5 — Number Sum *2026-06-02, version 1.9.1* I used to play this game every day, at least the daily challenge. Now the daily challenge will not open. The square grid is in off center but there is only the large square not the small squares. Last week there was an update which solved the problem for a few days but now it’s messed up again. Will you please fix it or should i just delete it? ### 5/5 — Broken or not broken *2026-06-02, version 1.9.0* Daily Challenge has been broken for a few days; please fix. Update: now fixed. Thanks Update 2: broke again. ### 1/5 — Doesn’t work anymore *2026-05-30, version 1.9.0* Can no longer play. Only gives a blank puzzle. ### 2/5 — Does not work anymore *2026-05-30, version 1.8.0* Up until May 27, everything worked well and the app was fun. But somehow, the display changed and there is no game to be played! You guys have to fix this! ### 3/5 — Défi quotidien *2026-05-30, version 1.8.0* Pourquoi je ne peut pas ouvrir le « défi quotidien »? ### 1/5 — Black screen on Daily puzzle *2026-05-30, version 1.8.0* The Daily Puzzle has a black/black screen. Yesterday’s game and today’s game is blacked out. Please fix!! ### 1/5 — Suzi’s *2026-05-29, version 1.8.0* The game is not allowing me to play it. It just comes up with a gray blank square. I am very unhappy. ### 1/5 — Jo *2026-05-29, version 1.8.0* What happened to the game? There is no display except for a gray empty window. Haven’t been able to play for 2 days now. Ads are annoying, but the disappearance of the entire game calls for a review of options. At this rate it’s better to delete it. ## Frequently asked questions about Number Sum ### What is Number Sum - Math Puzzle Game?
