I really like the actual game. it's the right amount of challenging but you can figure it out. You start to improve quickly, but it doesn't get boring, if you like math puzzles that is. BUT THE ADS!!! I expect ads in a free game, but not mid level in the middle of a round. I had 5 ads on one puzzle!!! thankfully the ads are short and relatively easy to skip, but come on. just keep them between levels at least.

Hi! Thank you for your review. We know that ads during gameplay aren’t ideal for everyone and can feel intrusive at times. Ads help support the game, and we carefully review player feedback to monitor how the experience feels overall. Your comments have been noted, and we appreciate you sharing them.

The game can be fun. Unfortunately, the game will give you whatever size level it wants to, and the more numbers a level has, the smaller the print. There needs to be a way to enlarge the numbers! The daily challenge levels are easier to see, but there is only one of those per day, unless you go back and replay old ones.

Hi! Thank you for your feedback. It’s great to hear you’re enjoying the game. We understand that smaller numbers on larger levels can make things harder to see. At the moment, there isn’t an option to enlarge the numbers, but we can see how that would improve the experience. We’ll share your feedback with the team so they can take it into account.

Should have taken more time to read reviews. It's a fun game, but after a short honeymoon period they interrupt game flow to play ads mid-level. I tried a few levels to see if it was only happening during daily puzzles or what, but it happens during all puzzles. Super annoying and I have un-installed it. I can deal with ads between levels, or if you exit off the screen/pause, but ads while you're actively playing a level? Awful.
