Unscrew Them All

**Unscrew Them All** starts simple: click a screw, it pops out, then click an empty hole to stash it. That's it for the first dozen or so levels -- "Easy Start" and "Wooden Basics" are basically tutorials with a timer. But almost immediately the catch shows up: screws can be blocked by other screws. You might try to take out one near the center, only to find another screw's head overlapping it, making it unclickable. That's when the real puzzle begins.

Your hands are doing a click-and-place loop. Click a screw head, it flies to your cursor. Click an open hole (one of those little dark circles hidden under planks or between them), and the screw snaps in. But open holes aren't always visible -- you have to remove certain screws first to reveal them. And some planks are held by just one screw, which makes them rotate when you pull it, blocking or exposing new holes. That rotation is a big deal in later levels like "Spinning Spruce" and "The Carousel".

The timer is always ticking, but it's not punishing in early levels. By the time you hit "Triple Layer" and "Crowded Corner", the timer becomes tight. You unlock the "Magnet Glove" upgrade around level 25, which lets you grab screws from slightly further away -- that helps a ton when planks are stacked and you can't reach. Another upgrade, "Quick Slot", gives you a temporary holding spot for one screw so you don't have to immediately place each one. That changes the rhythm completely: you can pull two screws, then place them in a different order, which solves some blocking problems.

The satisfying moments? When you pull the last screw from a big 6-plank stack and all the wood just slides away revealing a clean board with exactly enough holes. Or when you realize the order you need isn't the obvious one -- you have to skip a screw that looks easy and attack one that's buried. There's a level called "The Knot" where everything looks locked, but if you rotate a single-plank screw first, the whole layout shifts.

Later levels throw in colored screws: red ones need to go into red holes, and if you put them in the wrong color, you lose points. There's also "Frozen Screws" -- you have to click them twice; the first click breaks the ice, second removes it. And the "Double Helix" level has a spiral layout where you must unscrew from the outside in. The difficulty doesn't ramp smoothly; some levels feel impossible until you spot one specific screw that unsticks everything.

Honestly, the game doesn't explain all this upfront. You learn by failing. And that's fine -- the loop is short enough that retrying a level takes seconds. The best runs feel like a flow state: click, place, click, place, whole planks crashing down, timer still green.
