What's In Every Envelope
Each Rumble Rigs Dispatch is packed with things to collect, build on, and brag about at school.
Each Rig has its own character card with stats — power, speed, dig depth, payload capacity. Built to trade, built to compete.
How does your Rig stack up to the actual machine? Side-by-side comparison of the character vs. the real-world counterpart.
A labeled technical diagram of the real machine. What does a hydraulic arm actually do? Now your kid knows.
Real construction math problems. If Unit 003 can move 12 tons per scoop, how many scoops to clear the site? This is math that matters.
One premium sticker per dispatch. Water bottles, lunch boxes, folders — your kid's Rig goes everywhere they go.
Scan the code to watch the actual machine doing actual work. The connection between character and reality is where the magic lives.
How It Works
No apps. No screens. Just a really exciting piece of mail.
Sign up for $10/month and choose your dispatch start date. That's it — no commitments, cancel whenever.
Each month features a brand new Rig — numbered, named, and unknown until it arrives. The mystery is part of the fun.
A bold, official-looking Rumble Rigs Dispatch envelope arrives addressed to your kid. This is their mail. Their moment.
Every month, same excitement. New unit. New stats. New challenge. The collection grows and so does the obsession.
For Parents
Every Rumble Rigs Dispatch is built around real STEM concepts — engineering, physics, and applied math wrapped in something kids actually want to open.
The anatomy blueprints teach real mechanical vocabulary. The job site challenges use construction math that connects numbers to the real world. And the spec sheets spark curiosity about how machines actually work.
