How it works, step by step

  1. 1

    Queue joined players into a MemoryStoreSortedMap keyed by skill/scope.

  2. 2

    Matchmaker loop batches ready players when queue depth or timeout thresholds hit.

  3. 3

    Reserve a place via ReservedServers on TeleportService for a fresh match server.

  4. 4

    Teleport party members together with TeleportOptions storing match metadata.

  5. 5

    Handle teleport failures gracefully: refund queue position, notify via toast.

Concepts you'll use

  • MemoryStore queues
  • ReservedServers
  • Party-coherent teleports

Mistakes that cost you players

  • Polling MemoryStore too aggressively hits throughput quotas.
  • Losing party grouping across teleports splits friends into different matches.
