ALPHA: 2-player LAN cooperative Balatro for Windows Steam.

About this mod Author’s original text

BalatroCoop

A 2-player LAN co-op mod for Balatro.

Both players play through the same run together. Blind scores are combined, progression is synchronized, and both players share the shop.

Current version: 0.2.1 Alpha

This is an early release, so bugs and desyncs may still happen.

Installation

If you're Mod Manager / r2modman, install BalatroCoop normally and let the manager install its dependencies.

BalatroCoop requires:

  • Steamodded
  • Lovely

Manual installation

Install the dependencies first:

  • Steamodded
  • Lovely

Then:

  • Download BalatroCoop.
  • Extract the ZIP.
  • Open File Explorer.
  • Click the address bar and paste:

%AppData%\Balatro\Mods

  • Copy the entire BalatroCoop folder into the Mods folder.

The final path should look like:

%AppData%\Balatro\Mods\BalatroCoop\main.lua

Do not copy only main.lua, and make sure you don't end up with:

BalatroCoop\BalatroCoop\main.lua

How to play

Both players need BalatroCoop installed.

  • Open CO-OP / LAN.
  • One player clicks Create Room.
  • Send the displayed LAN IP to the other player.
  • The second player enters that address into Host LAN IP and clicks Join Room.
  • Both players choose their decks and click Ready.
  • The host clicks Start Together.

For two game instances on the same PC, use:

127.0.0.1

BalatroCoop uses TCP port:

22122

If Windows Firewall asks for permission, allow Balatro on your Private network.

Recent Steamodded and Lovely versions are allowed even if they have not all been individually tested.

Do not expose TCP port 22122 directly to the public internet.

Bug reports

  • Lovely version
  • whether you were Host or Guest
  • what happened before the problem
  • screenshot, video, or crash log if available

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide. These mods need a community loader first — the bundled readme usually points to its download.

Dependencies

Install these first, or the mod will not work:
