Nail Stack!

Slide, drop, and pray—your nail tower sways with every addition. Can you reach the top without a collapse?

You know that moment when a stack of anything leans just a bit too far? Nail Stack! lives in that space. You slide a nail left or right across the screen, line it up over the tower below, and let it drop. The goal sounds stupidly simple: keep stacking nails as high as you can. But every nail lands on the last one's tiny head, and the physics engine has zero mercy. A millimeter off and the whole thing starts swaying like a metronome. I've caught myself physically leaning with the tower, as if that would help. The challenge ramps up fast. Early on you're laughing at how easy it is—drop, thunk, drop, thunk. Then the tower gets tall enough that the shadow guide starts lying to you. The nails aren't perfectly straight; they shift slightly on impact, and each new addition magnifies the wobble. There's a particularly cruel moment when the nail hangs half off the edge, and you think you can save it by dropping the next one slightly opposite. That never works. The tower doesn't forgive. It just waits. What keeps me coming back is the one-more-run itch. A round takes maybe thirty seconds. You're never more than a few drops away from either disaster or a new personal best. It's the kind of game you open while waiting for a video to buffer and suddenly twenty minutes are gone. If you like hypercasual games that test your nerve more than your reflexes, this one lands perfectly. Just don't blame me when you see nail towers in your sleep.

Slide the screen to move

Watch the shadow, not the nail. The shadow shows exactly where it'll land. Short, quick swipes beat long drags when you need fine adjustments. If the tower starts leaning, don't panic—dropping a slightly off-center nail can buy you a second. Early on, aim dead center every time. The wobble comes later. Pause for a beat before each drop. Rushing is how you topple at 20 nails. When you're close to your record, ignore the height counter—it gets in your head.
