Light it up. Blow it up. No rules, no objectives — just fireworks.
Fireworks Mania is a casual physics-based sandbox where you play around with fireworks, set up firework shows, or simply blow things up — alone or online with friends.
Official trailer
Physics sandbox
Nothing goes off the same way twice
Every firework, spark and prop is simulated. Wire a rack of mortars together, light the fuse and watch the physics decide what actually happens — set the same show up twice and it will never play out quite the same.
Ten categories
Rockets, cakes, shells, mortars and more
Place fireworks almost anywhere, then link them with fuses that burn at different speeds to time the whole display. The in-game browser is organised into 10 categories: rockets, cakes, firecrackers, smoke, shells, mortars, novelties, tubes, fountains, props.
Online co-op
Bring friends along
The Multiplayer Update landed on 4 December 2024, adding online co-op with proximity voice chat. Host a world, invite friends, and build a show together — or just see who can make the bigger mess. It is co-op only; there is no PvP.
Built-in Workshop
Thousands of community creations, two clicks away
Fireworks Mania has its own Workshop built into the game, powered by mod.io — it is not Steam Workshop. Browse and install community-made fireworks, props, maps and characters without leaving the game, and anyone who joins your world downloads your mods automatically.
Want to build your own? The free Mod Tools run in the Unity editor and need no coding.
Maps
Town, City, Ranch, Flat
Four maps ship with the game, from a full town down to Flat — a bare plain with nothing on it, for when you want a blank canvas. The Workshop adds many more.
Blueprints
Save a show, share a show
Blueprints save an entire setup so you can load it again rather than rebuilding it. They
are plain .json files, so you can send a show to a friend and they can drop
it straight into their own Blueprints folder.
