Loco!

Loco! is a free real-time multiplayer card game played in the browser. Two to ten players match cards by colour or symbol to empty their hand first. A match runs as a best-of series, and it is won on rounds taken rather than on points. Turns do not gate play. Any player holding a card identical to the one on the pile can put it down out of turn, at any moment, and identical cards go down together with their effects stacking. A player reduced to one card has to announce it; opponents then have a five-second window to catch them if they did not, and a catch that finds nobody costs the caller a card. The 112-card deck adds two cards of its own: Swap, which takes another player's hand, and Global Switch, which passes every hand at the table one seat along. There is no account and nothing to install: a nickname, a table code, and a browser. Two to ten players per table, a 1v1 queue, and a single-player mode against the server.
