Not the ad…better than the ad

I think game ads are made by stupid people who don’t even try to get it right. This game is better than its generic math ad. The entire game board doesn’t equal 10 like shown. It takes thought and is far more creative than the ad running for it. I hate brain dead games, and this takes intelligence to play. Get it.

Update: just had a weird quirk in the December 7th calendar game, where every selection costed me a life even the correct selection. I paid for no ads, but can see how someone who did not would be very annoyed by this malfunction.

don’t fix what ain’t broke

The function that automatically erased incorrect numbers after selecting the correct ones has been removed. Now, players are required to manually erase all incorrect numbers. I find this function to be repetitive for no good reason. With this game, I picked the lesser two poisons. Ads, I understand as they make revenue for the company as annoying and frequent they are. But removing the function of erasing all incorrect numbers AFTER you’ve already selected the correct ones??????

There’s no real reason no matter how they spin it but I put in a ticket inquiring the new development and was told verbatim that, “This change was made to enhance the gameplay experience by encouraging more active and deliberate participation from players, at the same time, making the game more challenging.”

I personally don’t find this change enhancing or encouraging but it is what it is?????

I’ve reached 950+ levels and to have this new development take place, I find myself not playing Number Sum as much and frustrated enough to write a review at 3:44AM. Out of all things to “fix”, this wasn’t it and a poor decision in my opinion.

It feels like whoever OK-ed this change was the kid that goes, “Oh teacher, you forgot to collect homework!! 🤓” right before class ended.

The game is great, customer service was amazing, Polina gave me a timely, thorough, and polite reply and I’m not mad, just disappointed.

Hello! We're sorry to hear that the recent change in gameplay has affected your enjoyment of Number Sum. We appreciate you taking the time to share your detailed feedback and understand that the adjustment to manually erasing incorrect numbers can alter the game experience for our long-time players. Our intention was to introduce a layer of challenge and engagement by requiring more active participation, but we realize that changes like these can be divisive. Your feedback is invaluable to us as we aim to balance making the game interesting and maintaining the elements our players love. Thank you for your understanding and for being such a dedicated player. We hope you continue to find joy in the game, and we'll take your comments into account as we plan future updates.

More ads?

First, I love the game. Challenging, addicting, fun. Keeps this retired persons brain functioning. I would give it a 5 star rating BUT the addition of ads during games is unacceptable. I understand that ads are required to make games financially feasible for developers. I’ve not purchased the game so I accept whatever ads the developers choose to display before starting play or between games but interrupting every game multiple times is, as I stated previously, unacceptable. I guess I’ll have to determine my next steps. Continue as is (extremely irritating), delete the game which I hate to do, or pay the purchase price which I have never had to do previously. DUH, guess what, getting more subscribers is obviously the reason for inserting ads in games.

Hello! We're thrilled to hear that you find our game challenging, addicting, and fun, especially as it helps keep your brain active in retirement. However, we understand your frustration regarding the in-game ads. While ads are essential for supporting the game's development, we recognize that their placement can impact your gaming experience. We're constantly evaluating how to balance this and appreciate your patience. Your feedback is valuable in this process. Thank you for sharing your thoughts and for considering your options. We hope you continue to enjoy the game.
