Released 2026-10-16. 8 updates since release, the newest 2026-10-16.
Earlier update: PvP matchmaking (2026-10-16)
- Press PLAY: if another player is searching, you're matched against them in one arena, their name on their castle. Nobody around? You face the AI after 10 seconds, or tick 'wait for a human' to keep searching. Leaving a PvP match for 15s forfeits it.
Earlier update: Smarter enemy, balanced towers (2026-10-16)
- The enemy now builds a real tower defense. Tower cards rebalanced: Chapel Bells, Spirit Totems and Lucky Wheels hit harder, Gear Turrets fire a bit slower, tower legendaries build many more towers. How to Play explains tower commands, target hero, selling, your hero and keep. The menu no longer grabs your mouse.

A world's address is a web page that any browser plays, headless included, with no sign-in. https://www.spawn.co/@arc_keeper_77/card-master-tower-brawl@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.
The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @arc_keeper_77/card-master-tower-brawl; where, players and leave read and end it.
