Matchmaking and Reconnection

Use this reference for room discovery, filtering, and reconnect workflows.

Matchmaking Rules

• Set room metadata in onCreate for mode/region/skill filters.
• Use metadata and seat availability in matchmaking selection.
• Keep metadata consistent with room runtime state.

Reconnection Pattern

1. In onDrop, mark player as disconnected.
2. Allow reconnection for a bounded timeout.
3. Restore session if token is valid.
4. Expire and remove player if timeout passes.

Example Timeout Policy

• Casual match: 20-30 seconds grace.
• Ranked match: 10-15 seconds grace.
• Tournament: strict policy with admin override.

Operational Checks

• Reconnected clients rebind to prior player state.
• Duplicate sessions for same player are rejected.
• Expired reconnection tokens are invalidated.
