Undercover plays out remotely, in the browser, with nothing to install: one link is enough to gather 3 to 12 players around a 3D table, with voice chat.
Everyone gets a secret word. The civilians all share the same one; the undercovers get a neighbouring word, close enough to slip by unnoticed; Mr White gets none and has to guess the civilians' word to take the whole game. Each turn, one clue per player, then a vote: whoever the table points at is eliminated and their role revealed.
The game needs JavaScript and WebGL to run. Turn them on, or open undercover.chsfdjr.com/en/ in a recent browser.
