- This program is a two player adaptation of the card game "UNO".
- In it, you play against the computer. It is assumed that you are familiar
- with the game itself. This document explains the operation of the program
- and the quirks of the program.
-
- The program is non-graphic, and should work on a Mono or CGA adapter.
- It might work on an EGA system as well, but I have no way of testing that.
- If run on a color system, the cards displayed are displayed in appropriate
- colors to make the game much easier than on the Mono display.
-
- To start the game, enter UNO at the DOS prompt. The screen will display
- the credits, and then, in most cases, display your hand, the card showing on
- the discard pile, and the number of cards in your opponent's (the computer's)
- hand. Wild Draw 4 cards are displayed blinking (on most monitors) to make
- them stand out. You always go first unless the first card showing in the
- discard pile is a SCIP or a DRAW 2. In that case, you are skipped (and are
- dealt another two cards in the case of a DRAW 2), and the computer goes first.
-
- On your turn, you will be prompted for your action. If you have a
- playable card, you may play it, by entering a mnemonic code for the card.
- these codes are 1 or 2 characters. In the case of an ordinary card, the code
- consists of the first letter of the color (ie - R for RED, B for Blue,
- G for Green, or Y for Yellow) and the number or first letter of the card
- ( ie - 0,1,2,3,4,5,6,7,8,9 for number cards, or S for SKIP, D for DRAW 2,
- R for REVERSE). For example, to play a Red Skip, you would enter RS. A Green
- Draw 2 card would be GD, and a Yellow Reverse would become YR.
-
- To play a WILD card, simply enter a W. The program will prompt you to
- then enter the color you are changing to. You then respond with the single
- letter representing your selection ( ENTER is not required here). To play
- a Wild Draw 4, you enter W4. You will similarly be prompted for the desired
- color.
-
- The program will not allow you to play a card you do not have, and will
- not permit you to play a Wild Draw 4 if you hold a card of the current color
- in your hand. You ARE permitted to play a Wild Draw 4 if you have playable
- card in your hand, so long as no card in your hand matches the current color.
-
- To keep the code simple, the initial card on the discard pile will never
- be a Wild card. Since this is a two player game, the REVERSE card has no
- effect on the order of play. If you play a SKIP, a DRAW 2, or a WILD DRAW 4,
- it will be your turn again. On some occasions, if the computer has several
- such cards which are playable one after the other, it may play them in rapid
- sequence without you getting a turn. This is permitted, as these cards all
- end up skipping the next player, which is YOU. You may do the same to the
- computer when it is your turn.
-
- If it is your turn, and you have no playable card, you may DRAW by
- entering D. Your hand will again be displayed, showing the drawn card.
- You are prompted once more. If you now have a playable card in your hand,
- you may play it in the usual fashion. If you still have no playable card,
- you may PASS by entering P.
-
- If the computer has no playable card on its turn, it will draw a card.
- Since you will want to know that the computer has had to draw, a message to
- that effect is briefly flashed on the screen, and the computer will beep.
- If you attempt an illegal action, the computer will flash an error message at
- you and (sometimes) beep. If the computer has one card left (UNO), it will
- beep three times, and "UNO" will flash next to the computer's card count.
- There is no need for you to declare UNO, the computer knows how many cards
- you are holding in your hand.
-
- If the cards in the draw pile are used up, the top card of the discard
- pile (the one showing) will be retained, and the remaining cards from the
- discard pile are re-shuffled and are placed in the draw pile.
-
- Play ends when one player plays the last card. This is signaled by 5
- beeps and a Win message. If you won, the computer will display the cards
- remaining in the computer's hand. The points won are displayed regardless
- of Who won. You are then prompted to hit a key for the next hand. Play
- continues until one player accumulates 500 points and is declared the winner.
- At most points, you may abort the game by entering a Control-C.
-
- I started this game around 1980 on a TRS-80 Model 1, and have been
- puttering around with it off and on in my very limited spare time. I gave
- up on the TRS-80 version, and then revived the idea when I acquired Turbo
- Basic. This program is written in Turbo Basic, which made the development
- much easier. So far as I know, there is no other computer UNO game in
- existence. I hope this will be enjoyed my others as much as I enjoyed doing
- it.
