Hey! I'm not completely sure I follow the question. But the game is built a little differently from how you'd typically run TigerBeetle in production. In production you'd run a cluster of replicas (see https://docs.tigerbeetle.com/deploy/hardware#cluster-of-repl...) and then you'd have your application connect to the cluster using one of our client libraries.
The game is more a reflection of how we do simulation testing (as the post mentioned). You can find the code for that here: https://github.com/tigerbeetledb/tigerbeetle/blob/main/src/s....
