The way I was taught to play Uno, the reverse card changes the direction of play.if you’re taking turns clockwise, it changes it to counterclockwise.
However, I often hear people say “uno reverse card” in the context of saying “whatever you just tried to do to me, I’m turning it around on you”. That seems to me to imply that in the game, the reverse card turns things around on the other player. Like if they play a +2, you can play the reverse card and make them pick up 2. Is that the way some people play?
Is this one of those “house rules” situations where some people make up rules different from the official ones? Like the famous Monopoly rule where people put a pot of money in the middle that you win when you land on free parking, even though the official rules say nothing happens on free parking
Reverses the order of play when 3 or more people play or behaves like a skip when only 2 are left.
My kids brought home from kindergarten the house rule that you can discard all cards you hold with the same number at the same time when it is your turn so long as the bottom card matches the suit being played. Very chaotic but they love it.
Grouping like cards is essential if the ruleset forces you to pick up a lot of cards.
It also works to rubberband the game a bit, since more cards increases your chances of playing multiple cards.
