Balatro Multiplayer Speedrunning

Head-to-head Balatro Speedrunning. There are many ways to play but generally 2-16 people in a lobby face off on the same seed, the first one to get to the end of the seed wins.

This is the Speedrunning mod of the Balatro Multiplayer Platform. It runs on top of MultiplayerAPI, which owns the connection, accounts, lobbies, matchmaking, and leaderboards. Sibling mods on the same API include PvP. The server lives in BalatroMultiplayerServer.

Installation

Launchers

Launchers are the easiest ways to get modded Balatro running quickly. We have two main launchers we support:

R2 Mod Man

We recommend downloading the mod with r2mm if you intend to play it casually. You can download r2mm here: https://r2modman.com/

BET

Otherwise you can use own custom closed source launcher called BET, which is intended to be a successor of BMM. You can download BET here: https://new.balatromp.com/download
