Closed it out opened it up went to next level and poof ad again. This game has the potential to be a great game IF it didn’t bombarded you with ads. Deleted the game already at level 6…. Off to try a million other games! When you remove the ads, I’ll play it. ### 1/5 — Paid version still makes you sit through ads *2025-07-13* I tried the game, enjoyed it enough to pay for the VIP no ad version- except I still have ads. If you get stuck on a level you either have to watch an ad or pay money to try again, even with the VIP version. It’s basically just an ad machine. ### 2/5 — to many commercials *2025-06-21* good game just way too many commercials in it just too play a few games ### 1/5 — Constantly pauses music *2025-06-11* The games are fun enough, but if you’re listening to music it constantly pauses it. It’s very annoying. **Developer response:** Thank you for your feedback! We've fixed this issue and released an update on the App Store — version 1.30, published on June 15. Please update the game when you have a chance! If you’re enjoying the game, we’d really appreciate it if you could leave a higher rating and share it with your family and friends. Your support means a lot to us and keeps us motivated through challenging times! ### 1/5 — Holy ads Batman !!! *2025-06-08* Ads are out of control and long! No thanks **Developer response:** We're really sorry about your experience with the ads in the game! If possible, please consider purchasing the ad removal pack — it’s not too expensive and it’s a big motivation that helps us get through these tough times! ### 1/5 — Full of ads *2025-06-04* If I wanted ad I’d watch rv **Developer response:** We're really sorry about your experience with the ads in the game! If possible, please consider purchasing the ad removal pack — it’s not too expensive and it’s a big motivation that helps us get through these tough times! ### 3/5 — Sometimes it works *2025-06-03* It’s actually a fun puzzle game but the progress doesn’t always save. So you can play the daily challenge and it never saves that it was saved. I’ve done every level so the challenges don’t let you make more coins or win challenges. Glad I didn’t spend money on this. ### 5/5 — ابیی *2025-05-16* ناب ### 1/5 — Way too many ads *2025-04-17* Game is absolutely riddled with ads. Completely ruins the enjoyability of actually playing it. Make one mistake, and you have to watch a 2 minute ad. No thanks. Fun, but I deleted it in less than 2 full minutes. **Developer response:** We're really sorry about your experience with the ads in the game! If possible, please consider purchasing the ad removal pack — it’s not too expensive and it’s a big motivation that helps us get through these tough times! ### 3/5 — Fun BUT *2025-03-30* The game is very good but I think having a way to pause the timer so you can take a phone call or move would make it more enjoyable. Also the one puzzle game won’t let you go any farther than level 30 without sharing which is sad ## Frequently asked questions about Nuts & Bolts ### What is Nuts & Bolts - Screw Puzzle?
