This simulation is based on the official rules of the UNO card game, uses the standard pack
of 108 cards and is played entirely with the mouse.
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.
