A few days ago I shared my Hand & Brain platform. The main issue? You needed 4 people to play.

Not anymore.

You can now play against bots. Jump in anytime, no waiting.

The bots use Stockfish 18, so they're pretty strong. You play as the Hand, the bot plays as both Brains. Perfect for practice or just having fun when your friends aren't around.

What else is working:

Matchmaking queue with ELO pairing

Party system to play with a friend

Rated and unrated games

Game replays

Spectator mode

Still in beta. Bugs exist. I'm fixing them as people report them.

Your feedback makes this better!

After playing nearly 200 daily games with people from here, I wanted to try something completely different.

So I built a Hand & Brain Chess platform from scratch.

What is Hand & Brain?

Two teams of two players. The Brain calls the piece type (knight, bishop, etc), the Hand chooses which specific move to make. No other communication allowed. Pure chess chaos and teamwork combined.

The problem: There's nowhere to play this online with 4 real humans. Every platform I checked was missing something or didn't support the variant properly.

So I built one.

What's working:

Fully functional 4 player rooms with custom time controls

ELO rating system starting at 1500

Matchmaking queue with ELO based pairing

Party system so you can queue with a friend as a team

Rated and unrated matches

Spectator mode for watching games

Lichess style drag and drop board

Try it here: http://91.99.75.97

Full transparency: This is beta. Bugs exist. I'm actively fixing things as they come up, so if you find something broken, please let me know in the comments.

You need 4 people to start a game. If there's interest, I'm happy to organize test sessions in the comments so we can get games going.

Would love your feedback and help finding bugs!

P.S. Our Discord community is still growing and would be a great place to organize Hand & Brain games if people are interested: https://discord.gg/wFPQmUXGyS

Looking forward to seeing you on the board! ♟️
