Co-op games that run in a browser

Why the browser changes the maths

A browser game is one link. Nobody installs anything, nobody buys anything first, and nobody is on the wrong device — a laptop, a work machine that will not install games, and a phone can all open the same tab.

That matters most for the group that plays occasionally. A game that takes twenty minutes to set up rarely survives contact with a group that has an hour free.

What to check before picking one

• Can people join without making an account? A sign-up form loses half a group
• Is there a room code, or does it only do random matchmaking with strangers?
• Does it have voice built in, or does everyone need a second app running?
• Does it work on a phone, or is it desktop-only in practice?
• Is progress kept if someone wants to come back to it later?

How a Bit SaiGon answers those

Guests can play without registering, private rooms are shared by room code, voice chat is in the game, and it runs on a phone or tablet held sideways as well as on a desktop browser.

Progress is kept either way: a guest session on the device that made it, or a registered account that follows you across devices. A guest session can be upgraded later without losing anything.

Installing it anyway, if you want

It is also a PWA, so it can be added to a phone home screen or installed as a desktop window and opened full screen with no address bar. That is optional — the browser plays exactly the same.
