We've just rolled out a set of server-side updates and AMP enhancements that mean that on our official Kaboom! servers, when a new match starts you can get a ping in the #looking-for-group channel in our Discord server appropriate to what region you're in.
This means you'll know when new matches are starting immediately, and can quickly hop into them by clicking the included link.
If you're not already in the Discord server, head to https://discord.gg/vewSfBDj8C to get LFG notifications and get in on the action!
