I enjoy this game. I bought the full version and I never regretted it. But I really only thought to come and leave a review after the latest update. If you're ever stuck, use the hint system, and it explains step by step with clear images the logic to arriving at the answer. Simply amazing. 6/5 will keep playing.

I really like this game but the problem is I don't want it only in portrait, I want it in landscape, and can you please add like a dark theme, like the pitch Black color theme to? But this game is good, I think it is the only one that they need to do... But overall, this is was a very great game, very addictive and mind clearing, like it releases my anxiety and calms me down😸😸😸

Love the variants & game play, & don't mind the number of ads, but the issues with the ads need to be fixed! For almost every ad break, I just get a black screen instead of the actual ad. The ad never appears, nor the X, and I cannot hit the back button to exit the "ad" either. So I am forced to completely close and restart the app, wait for the app to reload, and usually still have to watch an ad once it restarts. Also a Walmart ad that takes you completely out of the app without warning.

Thank you for your review. I apologize for your experience with Ads. Please contact our support from the app and we'll try to find and solve the reason you get a black screen instead of an ad. And please send us also a screen shot of the ad that takes you out of the app and the URL it opens, we'll block it.
