How to Play UNO Party! New powers for a larger crowd

About UNO Party!, from BoardGameGeek:

Your goal in UNO Party! remains the same as in the original UNO game - empty your hand of cards first - but special rules and cards make the game playable with up to sixteen people at a time: The "Drawn Together" rule links two players who must draw cards at the same time. The "Point Taken" rule has all players pointing at other players, then each player must draw as many cards as there are fingers pointing at them! "Speed Play" lets players play a card out of turn - if they're fast enough... A direction tracker card helps keep track of the direction of game play.
