About this game

TO SCREW OR UNSCREW? 🔩

That is the question! In this exciting 3D puzzle game, your job is to carefully unscrew pieces from an object, and put the colorful bolts in the corresponding box. Easy in theory, but tricky to actually do when you need to figure out which order to remove the screws in so as to access all of the pieces. Colorful and interesting, these puzzles are also relaxing as you can calmly and strategically spin them around to find the exact right piece that you want to unscrew.

RIVETING FUN 🔧

Each level consists of a fun puzzle head together with tons of colorful screws, and your job is to unscrew the pieces and sort the colored bolts. It might seem easy at first, but you’ll need to pay attention to what color and which screw you’re going for, otherwise you’ll end up stuck! Thanks to the 3D puzzle though you can spin the piece around and around to find the perfect screw to keep the game going. In addition to regular levels, look forward to events and special offers that will keep the fun flowing!

You’ll love:

🧩 Colorful play – Levels feature brightly colored 3D puzzles that are held together by equally bright screws and nuts. In addition to the riot of color, fans of ASMR will love the sound and haptic effects, although these can be turned off if you want ultimate concentration.

🧠 Improved logic skills – Games can be both fun and educational, and Screw World is the perfect example of this. While you’re having fun unscrewing parts and sorting pieces, you’re also working on your logic skills as you figure out what order to remove everything in and how best to use your boosters for the ultimate advantage.

💆‍♂️ Relaxing levels – No timer means no need to rush your choices in this puzzle. Take your time and make use of the 3D aspect to spin the piece around as much as you want. You can also preview what bolts are hidden under pieces, allowing you to make the smartest moves.

😜 Extra fun incoming – In addition to the standard levels you can explore, events and competitions will help you hone your skills as you battle against other players to see who can finish the most levels. This would be a great time to break out your stock of boosters to make sure you come in number one!

NUTS AND BOLTS AND SCREWS, OH MY! 🧰

Unscrew bolts from pieces and watch them drop away, one by one, as you fly through levels and watch your stress melt away in this exciting 3D puzzle game that is perfect for all ages! Boosters, events, and more keep things extra exciting, but even the regular levels are sure to please thanks to their straightforward design and clean dynamics.

Good game. Puzzles repeat after level 80. Lots of ads and pushing you to buy packages.
