Cotime

Cotime is a free browser party game platform. No download, no account. Someone shares a link and everyone joins.

The games include The Descent (push-your-luck where the whole group shares a hull that can crack), Drawma (Pictionary), Constellation (word association with a star field), and Critters (insect tile drafting). Voice chat is built in. There's a Slack bot so teams can type /play to start a session without leaving their workspace.

Community-funded. No paywall.
