Stack anything you can get your hands on in this chaotic first-person tower-building game. Go solo or build with friends as you balance wobbly objects and use tools like tape jetpacks to reach ridiculous heights. How tall can you go before it all comes crashing down?
It's free to ask. The developer chooses who gets in.

About Stackable
Stackable is a first-person tower-building game where every object is a building block.
Your goal is simple: build the tallest structure possible using whatever items you can grab.
Play solo or team up in online co-op, working together to create massive towers that shouldn’t exist, but somehow do.
Gameplay
Junk keep's getting thrown into your backyard. Pick up the junk, place it carefully, and build the tallest tower you can and climb to the top.
Every placement changes the tower’s stability, forcing you to adapt, reposition, or reinforce weak points.
Objects have different weights, shapes, sizes, and balancing properties, meaning every run feels different. A tall, stable tower requires planning… or pure chaos and luck.
Progression & Upgrades
Earn points for every meter you stack, then use your points unlock a growing list of tools and upgrades, like:
- Tape – Secure objects together to prevent wobble or collapse.
- Jetpack – Reach higher placement spots faster or make mid-air saves when pieces fall.
- Upgrades – Climb faster, jump higher, spawn junk faster, & more.
Co-Op & Multiplayer
Invite friends to build together, each player carrying, taping, and climbing at the same time. Work as a coordinated team—or sabotage each other and watch the whole thing fall apart.
