I love this and play it almost daily! It has several options - daily puzzles, choose puzzles at your particular level, larger and more complicated puzzles, and competitions. Whatever kind of player you are, you will find what you want here. But where is dark mode?! The white background is just too overpowering at night, even with my blue light / nighttime filters. Honestly, it's a bit ridiculous that an app that is mainly black and white doesn't have any sort of night mode.

Frustrating. Used to enjoy this game but now ruined by the sheer number of ads that have been introduced at every opportunity. No longer mistakes or tips but in the middle of game play when you clear a number or other random times. made even more frustrating by the fact that the close button on the ad doesnt work so you have to sit for 30secs then use the back button on the phone. Now too frustrating to play and too may alternatives to stick with this one.

Hi John! Thank you for your review. We understand how frustrating frequent ads can be, and we’re sorry they’ve negatively affected your gameplay. Ads help keep the app free, but we’re actively working on finding a better balance. If you can't skip an ad, please provide a screenshot via the "Help" section in the app. We'll block it.

I have had this game for a while now and accept the adverts, but recently the adverts are taking almost 2 minutes and when they come every time you complete a series of numbers or rows what is a 5 minute game can take 15 minutes. This is unacceptable and makes the app not worth having. Since leaving my first review, I have continued to play, and the ads are way worse. It's shocking how bad it is.

Hi! Thanks for your feedback. We are sorry ads bother you. After a few seconds from the beginning of a video ad, an option to skip the ad must appear: a fast forward or a cross-shaped button. If there's no such button, please contact us via the "Help" in the app. We'll be happy to help!
