Build
Place mechanisms on a simple grid.
PUBLIC ALPHA · PLAYFUL SIMULATION SANDBOX
Railoom
Build a tiny network, set it in motion, and watch the pattern unfold.
Public Alpha. Features and behavior may change as the product evolves.
WATCH IT RUN
Build the route. Then let it surprise you.
Generators release Balls into a network of routes and mechanisms. Split them, hold them, merge them, and watch the timing turn into a moving pattern.
THE LOOP
Build → Play → Observe → Remix
Railoom is deliberately small and hands-on. Place parts, connect routes, press Play, then change one thing and see what happens.
Play
Start the simulation with one button.
Observe
Watch Balls move, wait, split, and merge.
Remix
Save a copy and reshape the network.
MECHANISMS
A few parts, many rhythms.
Split
Send traffic down alternating, random, or manually selected routes.
Reservoir
Hold a small group of Balls, then release the oldest as new ones arrive.
Teleporter
Jump between distant points and build layouts that fold across the board.
START HERE
No account. No setup ceremony.
Open the curated Starter Flow in one click. It stays temporary until you choose to remix it into a local project.
