About House Tandem
House Tandem is an indie game studio based in Columbus, Ohio. We believe the best games put players at the center of every decision — from accessible controls to inclusive design.
Our debut title, Tandemonium, is a physics-based tandem bicycle party game built for cooperative chaos. It started as a passion project and grew into a full multiplayer experience playable across web, mobile, and desktop. Since then we have added party games you play inside Discord with your phone as the controller: 7, 11, Doubles and Roulette.
House Tandem is the game studio of Users First, LLC.
We're proud members of Columbus's communities for game developers, tech builders, and creators of all levels:
Players & Users Come First
It's where we started, as Users First, and it's still the mission. Every decision starts with the experience you have — from intuitive controls to seamless multiplayer. If it doesn't make the game better for you, we don't ship it.
Fun Is Better Together
The best moments in gaming happen with other people. We build games around relationships, cooperation, and shared laughter — because a tandem bike doesn't ride itself.
Open Source, Open Doors
We believe in building in the open. Our code is available to learn from, build on, and contribute to. Great games grow when everyone can see how they work.
Embrace the Chaos
Physics-driven, not scripted. Every ride is different. The wobbles and crashes aren't bugs — they're the stories you'll tell your friends about tomorrow.
