Good game but far too many ads. The ones that pop up mid-game are skippable, but the ones that appear between games aren't, and they are excessively long and always for the same things. I have to close the app entirely and re-open to get rid of them. Will most likely delete the app, as it is close to unplayable with the number of ads interrupting the game.

It's somewhat challenging game that helps pass the time. Theres only a few things that would make this game better: 1. I wish they would stick to ads in between levels. The mid level ads are very distracting. I will be working on a row of numbers, and the ad pops up completely losing my train of thought. 2. There is an option for subtotal for the rows and columns but not the ones that lay within the box. 3. I really wish there would be a dark mode since I will sometimes play when I can't sleep.

Hi, we appreciate your feedback! It's great to hear that you find the game challenging and enjoyable. Your points about mid-level ads causing disruption and the desire for subtotal options within the boxes are noted. We understand a dark mode would enhance your nighttime play, making it more comfortable. Thank you for sharing!

frustrating. Great game, but way too many ads, especially in the middle of the game. TODAY I DELETED THIS GAME AND I HOPE NOBODY ELSE EVER DOWNLOADS IT. THE NUMBER OF ADS MAKES IT FEEL LIKE A SCAM, AND THE DEVELOPERS' RESPONSES ARE ALL THE SAME AND APPEAR MEANINGLESS AS THEY NEVER REDUCE THE ADS. Yes it is free but so are many other apps and they don't have heaps of disruptive ads like the game does.
