How many cards are there in a standard Uno deck?

In a standard UNO deck, there are a total of 108 cards. Let's break it down:

• There are four suits, Red, Green, Yellow, Blue, each consisting of one 0 card, two 1 cards, two 2s, 3s, 4s, 5s, 6s, 7s, 8s, and 9s;
• There are also two Draw Two cards, two Reverse cards, and two Skip cards in each suit; (This makes a total of 76 number cards.)
• In addition, there are four Wild cards and four Wild Draw Four cards; (This makes a total of 8 wild cards.)

Therefore, the breakdown of the deck is as follows: 76 number cards + 8 Wild cards + 24 function cards (Draw Two, Reverse, Skip) = 108 cards in total.
