Word Screw - 3D Unscrew Bolts is a fresh evolution of the popular 'screw jam' genre, blending mechanical disassembly with vocabulary training. Instead of simple grids, players are presented with beautifully detailed 3D objectsโfrom hamburgers and toy robots to complex dollhousesโcovered in letter-nuts and pins. You must rotate the objects to find hidden letters and unscrew them in the correct sequence; if you remove the wrong bolt first, the shifting plates may block your access to the letters you need next. Developed by Astrasen, the game is praised for its clean 3D graphics, smooth haptic feedback, and 'zen' approach to difficulty. With no timers and a stress-free atmosphere, it's designed to help players improve their spelling and spatial reasoning while enjoying the satisfying ASMR sounds of metal components falling away.
The biggest challenge in Word Screw isn't spelling the word, but managing the order of your letters. Since your 'letter tray' at the bottom of the screen has limited space, you must unscrew the letters in the exact order they appear in the word. Before you tap, rotate the 3D model 360 degrees to see if a letter is being held up by multiple bolts. If you release a letter too early that doesn't fit the current word, it will clog your tray and force a level restart. Always aim to 'clear the path' by removing non-letter screws first to give the letter-nuts a clean drop path.
As of the February 2026 update, Word Screw features 'Exploration Zones' and special events like the 'Valentineโs Day Fantasy.' Collecting letter fragments hidden within levels allows you to unlock Treasure Chests containing rare skins for your screws (like heart-shaped bolts or chrome nuts). The game uses a 'Prop System' where you can use a 'Magnet' to instantly pull a blocked letter or a 'Drill' to remove a stubborn pin that is preventing a plate from falling. Use these sparingly, as they are best saved for the 'Extreme' difficulty levels found every 50 stages.
If your tray is full of incorrect letters, you can use the 'Trash Can' booster to remove one, or watch a short ad to expand your tray by two additional slots for that level.
Yes! Many levels have 'Bonus Stars' or hidden letters inside hollow parts of the models. Be sure to use the 'Peek' feature or rotate the object to look inside gaps.
