Cairn

Stack stones, platform past impossible gaps, and see how far one little cairn can carry you.

Cairn is one of those games that looks simple at first—a tiny stone figure in a minimal landscape—but then you press space and realize the jump has weight. You hold it to charge a leap, tap it mid-air for a double jump, and suddenly every ledge becomes a puzzle about timing and momentum. I died a lot at first, mostly because I kept trying to play it like a normal platformer. You can't just run and hop. You have to read the terrain, judge the arc, and sometimes stack stones to make your own platform. That stacking mechanic is the hook: you pick up fragments and place them to build steps, bridges, even little towers to reach higher ground. What kept me coming back was how the game uses negative space. There's no music, just ambient wind and the soft thud of stone on stone. The world is mostly silhouettes and gradients, which makes every successful traversal feel earned. The controls are tight but not forgiving—you'll slide off edges if you're careless, and the double jump is more of a tap than a full extra jump, so you have to use it deliberately. One moment that sold me: I spent five minutes trying to cross a wide chasm, built a cairn twice as tall as my character, jumped from its top, and still fell short by a pixel. But then I realized I could stack stones on the far edge, and that completely changed how I approached the rest of the level. There's no hand-holding here. No tutorial text beyond a simple control prompt. You figure out the stacking radius, the jump charge sweet spot, and how to balance stones without them tumbling. Cairn respects your intelligence, which is rare in browser games. If you like quiet, meditative platformers that make you think spatially, this one will eat an hour without you noticing. Just don't blame me if you start seeing cairns in your sleep.

Charge your jump fully for maximum height, but tap mid-air for a quick correction—don't waste the double jump early. Stack stones in small clusters rather than one tall column; they're more stable and easier to climb. The slide is your friend: you can slide down steep slopes to gain momentum for a longer jump. Watch for subtle color changes in the environment—they often mark hidden ledges or safer paths. If a gap seems impossible, look for nearby stones you can drag; building your own bridge is almost always the intended solution.
