One Million Chessboards

I made a website. It’s called One Million Chessboards. It has one million chessboards on it.

Moving a piece moves it for everyone, instantly. There are no turns. You can move between boards.

You can play it here.

One Million Chessboards is a follow up to One Million Checkboxes, a surprisingly popular game that I made last year.

It was a little more technically challenging to make! It turns out that there’s a whole lot that goes into running a million simultaneous games of chess.

Unlike One Million Checkboxes, I’ve tried to design this site to handle some degree of load. Although to be honest I have no idea how it’s going to perform (or whether it will get enough traffic for that to matter!). I’ll do a proper writeup of the design once I see how it performs.

There’s a (very short) summary of the details here if you’d like to see them.

Anyway. That’s my new game. I hope you enjoy it.
