# Party game maker: short rounds, secret roles, everyone together > Describe the party game you want to play with your friends. Your agent builds it, and Summer runs the match: quick play, parties, chat and a board of total wins. - URL: https://www.summerengine.com/zh/party-game-maker - Keyword: party game maker - Related: https://www.summerengine.com/zh/online-multiplayer-game-maker A party game is quick to join and loud to play. Friends jump in together, strangers fill the rest of the match, short rounds keep everyone laughing, and a running count of wins brings people back. Summer Engine gives you each of those pieces, so the work goes into the rules that make your game funny. Players press Play, alone or with their party, and quick play fills the match. Summer starts a server for it, where your rules run the rounds, hand out secret roles and keep the score. When the match ends, each winner gets a win on the board and everyone can jump straight into the next round. You build it by asking. Your AI agent follows Summer's multiplayer skills in order: the server and client, instant movement, rounds and roles, matchmaking and parties, chat, and the wins board. Test it with several players on your own computer before anyone joins. ## Quick play for up to 16 players Summer has measured matches of up to 16 players, a good size for a crew of suspects or a round of chaos. Players press one Play button. Friends in a party land in the same match, and quick play fills the empty seats with other players. ## Secret roles the server keeps secret The server deals the roles at the start of each round, and each player's game learns only its own. Every action is checked against the player's real role, so a modified client cannot peek or cheat. When the round ends, the server reveals everyone's role. ## Short rounds, chat and a reason to come back Players talk in the match with built-in chat. The server adds a win for each winner when a match ends, and a wins board shows the top 50 and each player's own place. A bad round is never more than a minute from the next one. ## From the group chat to a live game Plan the rules with your friends on the Summer Board, let your agents build them, and test the game with Local Play. When it is ready, your agent publishes it on Summer Games for Mac and Windows after you approve, and your friends join with their Summer account. ## FAQ ### How do I make an online party game?
