You can only use a number card as your last card.Your turn is not skipped after you draw cards.(the same goes for +4 and +4, +4 and +2 as long as they have the same color) You can put down a +2 after a +2 to let the next person draw 4.However if there're enough interest, I may add some customization options for rules. Puno uses a set of rules my friends and I found most fun. I understand everyone has their own set of rules for uno. Players can join at the middle of a game.Runs in your browser & optimized for mobile and desktop.I was frustrated I can't find one that meets our expectations, so I made one! Hi everyone, I was tring to find a website for playing uno so my friends and I can play on any platform without downloading anything.
