😰 Feeling stuck in a long day, scrolling without a real break?

😄 Welcome to 3D Bolt Master®. It is a 3D screw game about observation, color matching, and planning the right order of moves. Rotate detailed 3D objects, find the screws holding each part in place, and sort every screw into a box of the same color. Simple controls and an unhurried pace make it easy to play a level during a short break.

This game is amazing, except as soon as I hit level 10, it's ads every time I mess up, or ads after every completed level. There's no option to buy an ad free version, so I sadly have to rate this low. If it changes, I'll come back to it, but sadly it's not worth the huge amount of ads I'm getting. Edit: I appreciate the developers response, and the ads wouldn't be so bad if they weren't 1-2 minutes long every time. 2nd Edit: The option to close it doesn't come until the 1-2 minutes is up.

The game is fun, but it's a money trap. You watch ads to get bonus helps when you're stuck, but I've tried a certain level over 10 times & when I try to watch an add for help, It says "This ad is not ready." It's not that my internet"s bad, cuz I can play online videos. It's a scam. You get to a certain point & the game becomes impossible so you use all your helps & ads are no longer available, so you must buy their starter pack with real money. Uninstalling now.

got as far as lvl 230 and now have to watch around 3 to 5 ads to finish. the game was good at first , but it just keeps giving me the wrong toolboxes. getting enough coins to buy boosters or another toolbox is rare, and quite honestly, I'm sick of watching ads to get through the level. The boosters they reward you with during the daily quest are always the same. The first chest always contains a broom instead of changing it to a drill or something. good for a while, but I'm sick of the ads 😑

Would be a great game, but for a few things. it randomly opens up your browser to a malware page while you're playing. And after a few levels you can't ever finish the game without watching 60 second ads to open a box, and you always must open 2 each level. Ads auto open the Play Store, or force you to open it yourself to exit the ad. Sad thing is, this would be a fun game that would make money if the company would give up all the sketchy stuff

I would give more stars if I wasn't linked to this game via an ad that SPECIFICALLY said "no interruptions", and "no forced ads". I uninstalled the MOMENT I was given a forced ad. The gameplay itself is ok at best, but seems like its not rng based and structured in a way that attempts to force you into using non-forced ads as well. Take off the FORCED ads and I'll maybe reconsider. **Edit** Dear devs, the issue isnt the ads themselves, its the false advertising, saying "no interruptions".
