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?

Broken or not broken

Daily Challenge has been broken for a few days; please fix.

Update: now fixed.
Thanks

Update 2: broke again.

Doesn’t work anymore

Can no longer play. Only gives a blank puzzle.

Does not work anymore

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!

Défi quotidien

Pourquoi je ne peut pas ouvrir le « défi quotidien »?

Black screen on Daily puzzle

The Daily Puzzle has a black/black screen. Yesterday’s game and today’s game is blacked out. Please fix!!

Suzi’s

The game is not allowing me to play it. It just comes up with a gray blank square. I am very unhappy.

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.

Daily challenge stopped working

Game was great but now the daily challenge is not updating. Just a gray square. Please fix

You ruined it!!! 🤬

This has been my absolute favorite game for 2+ years. I have played well over 6000 games on the main game, plus every special release, and countless weekly challenges.
Then my weekly challenge got stuck. It happens. But it always reset on Monday when the new set arrived. But for 2 weeks it didn’t leave the stuck puzzle leaving delete and download again as the only option!

YOU CHANGED IT!!!
Not the game itself, but now, regardless of the series, and regardless win or lose, I have to sit through an ad after EVERY PUZZLE!

Before, as long as I was winning, there were no ads.

I haven’t dumped the app yet, but I’m less inclined to even open it now.

Most of the games that I download end up being dumped because I get fed up with the endless ads.

Congratulations!
You took the best game ever and turned it into an also ran. You just couldn’t let an advertising dollar get away and lost a user and some potential sales commissions from less frequent but more engaged ads.

GREAT JOB!!
🤬🤬🤬

Needs more difficult options

There was actually a numbers game like this that I preferred because it had more difficulty, but it threw ads at you at random times, interrupting play and train of thought. I could not handle that so I chose this one but I wish there were more difficult games.

TOO MANY ADS

Thought this game would be fun but played 4 rounds that took 1 minute and had to watch 15 second in between each round - really!!! No thanks

Why are there endless DS with this update?

Ihave been playing the daily puzzle for more than three years and really enjoying it. Now, however, I have to watch ads before I can play the game. It says ads are only activated for hints (which I don’t use anyway)
so why am I seeing an ad at the beginning when I haven’t requested any hints. I don’t see why I have to pay for no ads and in addition pay for hints after seeing an ad.

Fun but frustrating

Good game, when you get to play. I am fine with ads, but between every game? You play, you watch. Fun while it lasted, but I am deleting.

Ads I the middle of a game

Ads are fine before or after a game. NEVER in the middle. I like the idea of the game but the implementation is horrible.

Interesting

However, I want to choose which level I play like in audio games

Crash / Freeze & too many ads

While the game had been enjoyable - fun enough to play many levels (& endure far too many ads) - the game has a crashing/freezing issue that began over the last few weeks. Attempted many issues to resolve, with the last resort being deleting & reinstalling (having to start over). It worked for one game session (6 levels), but the problems continue. Tried to contact support - but no reply. Too bad…have to permanently delete.

Could have been fun but crashes a lot

Don’t waste your time. Don’t download this game.

In the middle of a board, the app will crash about 4 out of 5 times. After it crashes and when you restart the app because you live in hope, you then have to watch another ad to get back to the same board where nothing is saved, and you have to start it all over again. Then you’ll end up deleting this game the same day you downloaded just like I did.

Okay game, but …

This game is worthwhile, yet the ads are CONSTANT and far out- weigh anything enjoyable in the game . I try to purchase no-ads options but still get ADS! Terrible and complete waste of time.
