Jackbox and The Jackbox Party Pack are trademarks of Jackbox Games, Inc. Aux Battles is an independent game and is not affiliated with or endorsed by Jackbox Games.
Jackbox (The Jackbox Party Pack) is a series of party games played on one shared screen while everyone else joins from their own phone at jackbox.tv, using it as a controller. One person owns the pack; everyone else needs nothing but the room code.
It needs a purchased pack and someone's console or PC to launch it from. If you want that same shared-screen, join-by-code shape but built specifically around music and free to play, that's what Aux Battles does.
How Jackbox works
The format, step by step.
One person owns the pack
A Jackbox Party Pack is bought once and launched from one device, a console, a PC, a streaming box, plugged into a shared screen.
Everyone else joins by code
Players open jackbox.tv on their own phone and type in the room code shown on the shared screen. Phones become the controllers.
Play through a mini-game
Each pack bundles several games, drawing, trivia, bluffing, word play. The host picks which one to play from the pack that's owned.
Submit, then judge each other
Most games follow the same shape: submit an answer, drawing or joke, then the room votes on favourites, often blind until the reveal.
Scores build across the game
A running score tracks who's winning as the mini-game plays through its rounds, closing out with a final standings screen.
Play a free round tonight, no pack needed
Aux Battles keeps the shape that makes Jackbox work, one shared screen, everyone else on their own phone, join by a short code, but the content is a music round instead of trivia or drawing: everyone submits a song that answers a prompt, then the room votes blind. No pack to buy, no console required, anyone can host from any device.
Need a prompt? There are 3,505 free prompts ready to go, or spin the wheel for one on the spot. Works the same at a house party, on a Discord call, or live on a Twitch stream with chat submitting and voting straight from chat.

Jackbox, answered
What is Jackbox?
The Jackbox Party Pack is a series of party games played on a shared screen while everyone else uses their phone as a controller by joining a room code at jackbox.tv. Each pack bundles several games across genres like trivia, drawing and bluffing.
Do you need to buy Jackbox to play?
Yes, one person needs to own the pack, on Steam, a console or a streaming device, and launch it from their own machine for the group to join.
Is there a free way to play something in the same format?
Yes. Aux Battles uses the same join-by-code, phone-as-controller shape, but the game itself is a music round: everyone submits a song to a prompt and the room votes. No pack to buy and no console needed, and there are 3,505 built-in prompts to start from.
Does anyone need to install anything to join?
No, for either format. Jackbox players join at jackbox.tv in a phone browser, and Aux Battles players join a room code the same way, both without installing an app.
Can it run on a Twitch stream?
Aux Battles can: connect a channel and chat submits songs and votes straight from chat, no extension. That's a separate mode built specifically for streaming, distinct from a local shared-screen game night.
