The object of the game is to get rid of all your cards. To win, you have to do this before the computer does!

Play your cards by matching the card on the discard pile in number, color, or type. For example, if the card on the discard pile is a yellow 5 you can play any number 5 card, any yellow card, or a wild card.

If you can't match the card on the discard pile (or choose not to play a card) you must draw a card. If you draw a playable card, you can choose to play or pass. If you don't play, you must pass.

Skip
Skip the other player's turn.
You get to play twice!

Draw Two
The other player has to draw two cards.

Wild
You choose the color of the discard pile.

Wild Draw Four
You choose the color of the discard pile and the other player has to draw four cards.

The game is for one player only. There is no point system.

There are no Reverse cards.

Draw Two cards don’t cause the player they’re played on to lose a turn.

After drawing, you can play any playable card in your hand—not just the one you drew.

There are no restrictions on when a Wild Draw Four card can be played.

You don't have to yell "UNO" (but you can if you want to).

Mostly to learn JavaScript—hence the name—along with HTML/CSS. People told me that building something was the best way to learn, so after finishing the Codecademy course on JS I thought making an UNO game would be a fun challenge. I made JUNO without using jQuery or other libraries to teach myself about working with the DOM, event handling, animation, and so on.
