Click a card to play it. Click the green flag to start the game. You start with 7 cards and when you can not use one, you have to draw a card. If you can use the drawn card, use it. You don't get skipped when you get +2'd or +4'd. Wilds and +4's allow you to change the color by saying R, G, B, or Y. You can click the recycle icon to change the background. You can also click the eye if you want to see the opponent's cards. You can only use a card if it is the same number, a wild, a +4, or the same color. For example, if the card was a yellow 4 and you had only a red 8 and a blue 7, you couldn't use it because it doesn't match the circumstances. What this means is you have to draw a card. If you have a card you can use, you must play it. Skips skip the other opponent's turn. Special rule: You can't have more than 15 cards. When you should get a 16th card, nothing happens.
Credit to Max_Standard for making the original project. Added a total wins variable (glitchy) that you can see the value of by looking in the code. It wasn't letting me create a cloud variable. Unfortunately, I can't fix any bugs in the game so don't tell me to fix one.
