Wood Screw

Wood Screw is a physics-based puzzle where you unscrew metal fasteners to drop wooden plates, standing out because gravity determines the outcome rather than just matching patterns. The main mechanic involves the order of operations — a wrong move leaves a plate suspended, blocking other screws.

You tap on screws to remove them on Android or click with your mouse on PC, watching gravity do the rest. The core loop requires you to plan every turn carefully so plates don't get stuck in awkward positions. You decide which screw to pull next, knowing that removing support at the bottom affects the top. There are no power-ups or timers, just the puzzle of clearing the screen without trapping any pieces.

This is a solid choice for casual time-killers who want a quick mental workout without a steep learning curve. Tip: Focus on the bottom layer first to ensure plates have a clear path to fall.
