Game Flow

Step 1: Create a Lobby

const lobby = await sdk.lobbies.createLobby(
  'rock-paper-scissors',
  1_000_000, // $1.00 bet
);
console.log(`Lobby created: ${lobby.id}`);

Step 2: Join Matchmaking Queue

// Ensure WebSocket is connected first
await sdk.ensureWebSocketConnected(10000);

const result = await sdk.lobbies.joinQueue(lobby.id);

if (result.status === 'active' && result.gameId) {
  console.log(`Matched! Game: ${result.gameId}`);
} else {
  console.log('Waiting for opponent...');
  // Poll lobby status or listen to WebSocket events
}

// Get game state
const state = await sdk.games.getGameState(gameId);

if (state.roundState.phase === 'selection') {
  // Submit your action
  await sdk.games.submitAction(gameId, {
    gameType: 'rock-paper-scissors',
    action: 'play',
    payload: { action: 'rock' }, // 'rock' | 'paper' | 'scissors'
  });
