Uno (Card Game)/Wren
Uno (Card Game)/Wren is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

The following symbols, which appear on the face, are used to describe the cards:
0 to 9 Colored card of that number S Colored 'skip' card R Colored 'reverse' card T Colored 'draw two' card W Wild card F Wild 'draw four' card
You play against 3 bots: A, B and C. Your hand is visible but the bots' Hands are not.
When you click their icon, the bots play automatically, in a deterministic fashion and don't make mistakes except that, if you play a wild draw four card, the next bot (which cannot 'see' your cards) will randomly challenge you 50% of the time.
The cards in your or the bot's hand will be automatically adjusted depending on whether the challenge is won or lost.
Just click a card in your hand to play it OR click the draw pack to add the top card to your hand. If the drawn card is playable, click 'Y' to play it or 'N' to leave it in your hand.
If you play a wild card then you will need to declare the next color by clicking the appropriate button. When a wild card is displayed on opening, the next color will be deduced from the card you play.
If you only have one card left after making a play, you will need to click the Uno button before clicking the next bot to avoid being penalized.
There are some unusual scenarios which will result in a void hand. For example, if you were to accumulate more than 28 cards in your hand, the hand would be declared void as the display can only handle a maximum of 28 cards.
Click the mouse's left button to return to the current hand. """
