About this game

Welcome to Nuts Bolts Screw Glass, a creative physics-based puzzle game that turns simple unscrewing into a test of logic, foresight, and strategic thinking. Each level presents you with a complex, interconnected mechanical contraption filled with bolts, gears, platforms, weights, and a delicate glass target. Your core goal is to carefully unscrew the right bolts in the correct order to trigger a seamless chain reaction that ends with the glass breaking. Unlike simple matching or tap games, this title rewards careful observation and critical thinking, making it a perfect pick for players who love mentally stimulating challenges that feel rewarding to complete. Whether you're playing for 5 minutes during a break or spending longer sessions working through tricky levels, the game offers a consistently fresh, engaging experience that never feels repetitive.

Start each level by taking time to observe the entire contraption layout, locating the glass target first before tracing all the connected mechanical parts back to the supporting bolts. Think several steps ahead to predict how removing each bolt will shift gears, move platforms, or drop weights, and identify the critical bolts that will start the desired chain reaction. For easier early levels, you may only need to remove one bolt to complete the challenge, but as you progress, you will need to unscrew multiple bolts in a specific order, paying close attention to timing to keep the chain reaction going. If your attempt fails, take note of what stopped the reaction, adjust your strategy, and try again until you find the perfect sequence.

Hundreds of levels, authentic physics, satisfying visual and audio feedback

Perfect for puzzle lovers of all ages, Nuts Bolts Screw Glass offers a fun, brain-boosting experience that feels rewarding every time you nail the perfect chain reaction.
