Do you remember the childhood card game UNO?!
Each player receives 7 playing cards and one card gets put out as an opening card. You go around in a circle, taking turns, putting down a number card of the same colour, or an alternate colour of the same number value. Simple right? Add +2 (Draw 2) and +4 (Draw 4), still no worries.
You're cruising along and then someone slams you with a Draw 4. Oh no! But then BAM you slam another Draw 4 ontop and before you know it, the player next to you is sweating pellets as he prepares to pick up 8 cards. No? DOUBLE BAM slams another ontop and we're up to Draw 12 to the unfortunate sucker that started it all (assuming 3 players).
But what if I told you that this is incorrect? This isn't actually how the game works? You're all thinking nahhhh @dolladu you're full of rubbish, you're drunk, go home. Well in fact I came across this little snippet of the one person in the world that actually decided to read the rules. It speaks for itself. Enjoy, and prepare to play UNO, the correct way!
Correct way in summary;
Never played UNO this way. Can't wait to try it out and play a childhood classic, the correct way!
