I've loved this app for years, but I'm strongly considering uninstalling it, because the ads have become INTRUSIVE AND FREQUENT. It used to be that there might be an ad at the end of every other game, but now there are annoying full screen ads, that CANT BE CLOSED, often 2 or 3 times between EACH game. The developer responded to say the ads were designed to be skippable after 5 seconds, but they ARE NOT. After ANOTHER response, saying ads are skippable, they're either lying or incompetent.

We're sorry for your experience. The popup ad shown between games is designed to be skippable after 5 seconds with fast forward/X/Close. Ad networks send a huge number of ads, and control how to skip ads + may show them in 2 parts. Sometimes there are problems, so if you see bad ads please contact support@aifactory.co.uk. Paid version has no ads.

I am not really sure how the levels work? However, the games I have played are usually fairly good when it comes to the difficulty level. The boards can be solved but sometimes you have to undo a few mistakes. I like that it is a free game and that adds do not take over the whole game.

Stop taking over my phone with ads!!! After every puzzle it gives an ad that if you try to close, it takes you to the page to download it!! Capitalist hijackers!!! I have to close and reopen app and then it still opens with ads. RIDICULOUS!!!!

We're sorry you're seeing a problem with ads. Popup ad between games (so it doesn't disrupt play) is designed to be skippable after 5 seconds with fast forward/X/Close. Ad networks control all ad behaviour including how to close it so please report any problem cases to support@aifactory.co.uk for us to investigate. Paid version has no ads.
