Dark screen option but crashes for my iPad.

So happy to find this has a dark screen option. 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.

Fun but ads

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.

Number Sum

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?
