Puzzle Bash is a collection of quick multiplayer word and number games you play in the browser, usually on your phones together in the same room. One person can start a room and share a short code; everyone else joins on their own devices. If you have a TV or projector, you can optionally open Display mode there so the whole group can see the puzzle board while each player uses their phone to play.
It is built for parties, classrooms, and family game nights, not for gambling or high-stakes competition. See FAQ for a short how-it-works overview.
