Let's Play Uno!

I'll explain the rules for the people who don't know Uno yet. It's really easy and you can already see most of it in the game, it even shows you which cards you can play There are cards with different numbers and colors, you have to either play cards with the same number or color of the card that was played before. If you can't play, you have to draw one card from the pile. Everyone starts with seven cards and the goal of the game is to lose all the cards on your hand as fast as possible. This is how the game can look like at the start (lame cards, I know xD)


The cards:


There are normal cards with the numbers from 0-9 on them but those don't have any special effect. There are also different kinds of special cards:
Wild Draw 4: The player next to you has to draw 4 cards and will be skipped. You're also allowed to pick the color that should be played next.
Wild: You're allowed to pick the color that should be picked next.
Draw 2: The player next to you has to draw 2 cards and will be skipped.
Skip: The player next to you will be skipped.
Reverse: The direction in which the players play cards will be changed/reversed.

Call Uno:

Before you play your second last card you have to call Uno. A button will appear above the cards and you have to click on it. Don't forget this because if you forget it you have to draw two cards from the pile
