Ratings and Reviews
Great Game !!
I’m enjoying this game. It is fast becoming my go to game. I almost didn’t download it because so many complained of ads. While I agree there are a lot of ads, I’m here to tell you to not let that deter you from downloading and enjoying this game.
For instance, I was intrigued by the “nuts & bolts” games so downloaded several to try. They all have ads. Some as many as 3 ads in a row and absolutely NO way out—you are forced to watch all ads, and those ads last anywhere from 70 seconds to almost 2 minutes. This game is not like that (and I hope the developers of this game never get that desperate (greedy). The ads on this game allow you to close them quickly. I understand developers put in a lot of effort to create a game worth playing and need to make money, so I will put up with ads — to a certain extent. This developer does not go crazy like so many do. Download a “nuts & bolts” game and you’ll quickly appreciate these developers.
I like this game so much that I would be willing to pay to be ad free. Heck, I would be willing to actually purchase this game if they asked a fair price.
BOTTOM LINE: This game is challenging. It’s fun. It’s addictive. I love it and am so glad I found it. (Ironically, I found it because it was one of the ads on the nuts&bolts game that I deleted).
Developers, PLEASE don’t follow the other developers and add more or longer ads. Please consider offering an ad-free option that is truly ad-free.

Hi! We're glad you enjoy the game and appreciate your understanding regarding ads. We do offer an ad-free version in the app's settings. Thank you for your detailed feedback and support! 💚
Increasing Ads becoming Unreasonable
This was a 5 star game, but the number of ads went from being reasonable to unbearable — not sure if it was a recent update or if the developers decided that once you get to a certain level that you’d pay for the app if they made it more annoying not to, but I no longer enjoy playing when every few moves I get interrupted by yet another ad. For me it’s having the opposite effect and I’ll probably stop playing.
A few minor changes could help with gameplay. Most of my mistakes were accidental. Rather than toggling the delete/select mode it’d be better to have two explicit buttons to select one or the other, where selecting the existing mode is no operation — then I could just click every time rather than having to always look and double check that I’m in the mode that I thought I was and not accidentally change it.
I’d also like a mode that lets me make mistakes and then just make me figure out where I made a mistake, if I did. Sometimes reverse engineering your mistake is its own interesting challenge.

Hi there, we appreciate your detailed feedback. We're sorry to hear that the increase in ads has affected your enjoyment. We're constantly looking at ways to improve the user experience, including better controls and gameplay modes. Your suggestions are very helpful—thank you!
QUESTION
I know someone else that plays this game, we are on the same version of the game, but some small details are changed and it makes the experience of playing a lot different. In my version, when I click a correct number in a column, it will update the sum on the outside of the box and the number I clicked will disappear. In their version of the game, when the click a number, it will circle the number, the number will remain on the screen, and a smaller number will be added next to the sum on the outside of the box while the original sum is not updated like in my version. Why is this? I’ve explored the settings and don’t see any option to change this and am wondering if I’m missing something. I would like to play their version of the game if possible because it’s a little more thought provoking
