UNO is a great game to play with the kids, and is one that can really get the heart pumping.
UNO is one of those games that can cause family rifts, arguments between colleagues and for childhood best friends to fall out.
But it is such a great card game; it's fun, competitive and can really get the heart racing! And because it's so small and neat, it's also a pretty awesome game to pop into your handbag when travellingwith the kids.
However, it seems that we have been playing it all wrong - well most of us anyway!
And the creators of UNO are here to make sure that we know the rules of play.
Taking to Twitter, the creators explained that there is one particular move that is not actually part of the rules and is one that most of us are guilty of doing.
If someone puts down a +4 card, you must draw 4 and your turn is skipped. You can’t put down a +2 to make the next person Draw 6. We know you’ve tried it. #UNO pic.twitter.com/wOegca4r0h

In a photo on the social media sharing site, the creators tweeted: "If someone puts down a +4 card, you must draw 4 and your turn is skipped. You can’t put down a +2 to make the next person Draw 6. We know you’ve tried it."
Yes, we have done it and, yes, it has won us many a game.
In the accompanying photo, they wrote: "You cannot stack, draw 2 and draw 4 cards."
Not surprisingly, many people have taken to Twitter to tell the creators exactly what they think of the so-called rule.
Listen just make the cards, let us do the playing

Well, we make special rules to make it more fun and brutal. It's a test of friendship.

So, will you be sticking to the real rules or your own?
