Slide Roulette runs PowerPoint karaoke for a room with a television and a phone each. The host opens a room on the big screen and everyone joins with a four-letter code. Nobody installs anything, and players don't need an account. A wheel picks the next presenter and deals them a deck they have never seen. Their phone becomes the clicker, with about a minute a slide. While they talk, the audience reacts from their phones. Afterwards everyone scores the talk for confidence, comedy and commitment, out of a hundred, and the slide the room reacted to most becomes a card the presenter can share. The decks are written to be presented: believable slides, charts and diagrams with no punchline of their own, so the laugh comes from the person at the front. Safe mode keeps the material fit for the office and is on from the start. Everything is available in English and Danish. Free for up to 8 players, with Classic and Lightning modes. A Party Pass opens a room for 48 hours with any number of players, Chaos and Tournament modes, extra games and your own uploaded decks. Companies can buy a week on an invoice.
