About this game

Stackpark is a building game where nothing can go wrong. You're a small character on a sunny island with a box of oversized toy parts that never runs out: cubes, bricks, blocks, plates, walls, pillars, ramps, orbs and caps, in twelve bright colours. Aim, click, and the part lands exactly where the preview said it would. There's nothing to collect, no budget, no timer and no way to lose. The whole game is whatever you decide to make.

Parts snap to a grid, and that's what makes it work. Your stacks line up whether you were careful or not. A wall you throw up in ten seconds is straight. A tower is a tower and not a lean. Parts turn in eighth-turns, so ramps meet ramps properly and a diagonal is a real diagonal. The grid handles the fiddly part, so what's left for you is the shape — the arch you weren't sure would hold, the staircase up the side of a tower, the pier out into the water that only exists because you had orbs left over.

Everything you build saves in this browser, one island at a time, and the title screen keeps every island you've built on. When something is worth showing off, press P. You get a picture and a link, and the link carries the whole build, part by part. Whoever opens it stands in front of the same thing and can add to it. Building on someone else's is the point of sending it.

How to play

  1. Start building. Pick the Showcase Island or a new one. Clicking the park hands the mouse to the game so moving it looks around. Esc gives it back and opens the menu.
  2. Pick a part and place it. Number keys 1–9 choose the part, the ghost shows where it will land, and a click puts it there. R turns it before you commit.
  3. Colour it. C flips through the twelve colours for the next part, and F repaints one already down without moving it. That's how a build gets its stripe, its roofline or its one red door.
  4. Fix mistakes freely. X removes whatever you're pointing at. Nothing costs anything, so there's no reason not to try the version you're unsure about.
  5. Walk around it. WASD moves, Shift runs and Space jumps. A build you can climb looks completely different from one you only ever saw from where you built it.

Questions about Stackpark

Is Stackpark free to play?
Yes. Stackpark is free, and there is no account to make and nothing to pay for. Your progress is kept in this browser on this device, so clearing your browser data clears it.
Do I need to download or install anything?
No. Stackpark runs in this browser tab. There is nothing to install and no app store involved — open the page and it starts.
Can I play Stackpark on a phone?
Yes, with one thing to know: on a phone, changing colour takes one tap more than everything else — you open the twelve colours, then pick one. On a computer, Q and E change it without letting go of anything. It plays on a phone, a tablet or a computer.

Drag the screen, or the mouse — look around. WASD, or the arrow buttons — walk and step sideways. Space, or the Jump button — jump. Click, or the Place button — put the part down. The full list is in the controls table on this page.
