I watch more ads than play. ### 1/5 — Deleted *2024-07-22* This is a good game and I’ve no objection to adverts but there are far too many. As a result the game is not enjoyable. Now deleted. ### 2/5 — Good but…. *2024-07-09* Gameplay is nice. A lot of challenging puzzles. Problem is the screw race. If you are rich enough to buy no ads, it’s good. But, if you have ads , you will lose by watching those ads that break into the game. While others can zip through without ads. So, while you watch, they are winning. It should be fair gameplay and is not. I used to enjoy the game. But, now there are a LOT of other screw puzzles out there that are just as good or better. ### 1/5 — Completely unplayable *2024-07-07, version 1.0.6* Even when you pay to remove ads, game play is constantly interrupted by ads. The ad finishes playing and up pops a notice saying you failed the level. AVOID! ### 2/5 — Ads toooooo long! *2024-07-05* I love playing this puzzle, but I’m ready to ditch it because I feel like it is nothing more than a moneymaking scheme. I believe you should get paid for the effort you’ve put into making a good game, but the ads are way too long! In the complicated puzzles, some pieces aren’t consistent in falling out of the way and getting hung up on another piece. Sometimes a screw will fit in some tight places but not at other times. ### 1/5 — Nope *2024-07-01* I’m only giving this game one star because I have to in order to leave a review. Let me start by saying I like this game. The puzzles are challenging, and it is legit fun. That being said there are WAY too many ads!!! As if that wasn’t bad enough, if you watch an ad while you are playing, your time does NOT pause. Also, if your time runs out and you want (or have to, like me) complete every level, you can do that as long as………you guessed it! Watch another ad. Game is great, WAY TOO MANY ADS!!!! ### 2/5 — Too buggy *2024-06-29* I really liked this game, but deleted it due to the bugs. There are spare holes for free, and spare holes that require watching an ad. Fair enough. But more and more often the free holes ALSO trigger the ads. Sometimes the time watching an ad counts against you, so when the ad is over, you’ve already lost. Of course you can replay after watching another ad. And the first screw you move triggers another ad. Rinse and repeat. ### 5/5 — SCREW: NUTS AND BOLTS *2024-05-25, version 1.0.3* I absolutely love this game!!!! ### 1/5 — Junk game *2024-05-16* Don’t waste your time. You wait while going through the ads just to be forced back to the beginning. Worst part is, the ads are for junk games that I already downloaded, tried, and deleted. ### 3/5 — Keeps jamming *2024-05-13, version 1.0.3* Have to keep signing out and then back in as it freezes on your “you have won” page after playing a level.
