I have used this app every day for a year, at least 3 puzzles per day. It's my go-to for relaxing and I am not bored in the slightest. Some puzzles are frustrating, some are genuinely entertaining. the paid for version is absolutely with it. Literally the only thing I would ask to add would be more specific instructions for the hint system. it says what each rule violation is, and then gives generic instructions, but ideally you would have step by step exact information. Great app! well done!

The game it's self is great, with a good interface and puzzels. However, the ads are the very long interactive ones that move the close button and have very long timers(occasionally 2-3 mins). They also occured very often and are aggressive, it's not one per puzzle, it's random. I once had one happen when I finished a puzzle and then 4 seconds later when opening the next. I would have been happy to pay for the app but it's subscription and imo quite expensive. The lifetime option is $37NZD

Thank you for your Feedback. Every app out there is using the same vendors for ads (Google, Meta & Applovin). Sometime bad ads are slipping through. We are blocking those when our players report them. We are trying to minimize Ads appearance as much as we can. We have a promotion coming in few days, hopefully the price point will be right for you.

As others have reported, it suddenly claimed it couldn't load ads and stopped working. There is no Ad Blocker, VPN, etc at my end. I did not change any settings or software. Other games, including a different Logic Wiz app, are able to load ads. Appears to be a blatant attempt to sell the Premium version. Not happy.

Thank you for your feedback, I apologize for the issues you have with Ads. We NEVER force anyone to become premium. If other apps load ads, and the reasons you mention don't apply to you, try restarting the app and/or your device. If you still cannot resume playing, please contact our support from the app and we'll investigate.
