Dos Card Game Rules and Setup: A Step-by-Step Guide

If you’ve mastered UNO and its various editions but are looking for a new challenge, the DOS card game is the next step. DOS puts a new twist on the classic UNO formula. While the basic concept of number matching remains, DOS introduces exciting new mechanics, including multiple discard piles and strategic wild cards.

You must use complex strategy and exciting moves to outwit your opponents. You need more skills to win the game, but you must first learn the rules.

Let’s explain the rules of the DOS card game in detail as a first step towards mastering the game. I will also reveal a unique game similar to DOS towards the end.

• A 108 DOS Playing Card Game
• Numbered Color Cards: 96 cards
• 4 Colors: Red, Blue, Green, Yellow

Understanding Wild Cards

• Wild # Card: This card can represent any number from 1 to 10 in its color. If drawn, the player decides which number it will be.

Setup

The first step in DOS is selecting a dealer. Shuffle the deck and let each player draw a card. The player with the highest card becomes the dealer. The chosen dealer distributes seven cards to each player, face down. You should not show your seven cards to anyone.

The dealer then creates a draw pile by placing the remaining cards in the middle of the players, face down. Two cards are drawn from the pile and placed to the side to form the center row.

How to Play the Game

The DOS Card Game starts with the player to the dealer’s left and proceeds clockwise. On your turn, there are four scenarios for playing cards:

1. Matching Cards
2. Matching Colors
3. No Match
4. Filling the Center Row

Matching Cards

In the case of matching cards in the game, you can match a card from your hand to a card in the center row with the same number, regardless of color. This is called a single match. For example, you can match a 5 card from your hand to a 5 card in the center row, regardless of color.

When playing cards in DOS, there is also a Double Match. This occurs when you use two cards from your hand to match the number on a card in the center row. The two cards you play together must add up to that number. For example, if there is a 7 in the center row, you can use a 3 and a 4 from your hand to match it. The color of the cards does not matter.

Color Matching

In color matching, you match cards of the same color to earn bonus points. There are still single and double matches in this case.

• Single Match: You match the number and color of a card from the center row with a card from your hand. If the cards you play meet these criteria, you can discard an additional card from your hand to the center row.For example, if there is a red 5 in the center row and you have a red 5 in your hand, you can place it on top of the red 5 in the center. After that, you can discard another card from your hand to the center row, such as a yellow 3.
• Double Color Match: You match two cards of the same color that add up to the number on a card in the center row. DOS card game rules allow a double color match bonus for this move, which forces opponents to draw one card for each double color match bonus.For example, if there is a green 8 in the center and you have a green 5 and a green 3 in your hand, you can play both together because 5 + 3 = 8. Your cards also match the color. After that, you can discard an additional card, and all other players must draw one card.

Unable to Match

If you are unable to match any of your cards with the cards in the center row, you must draw a card from the draw pile. If the drawn card can be used to make a number or color match, play it. Otherwise, discard one card from your hand to the center row according to DOS card game rules.

Reloading the Center Row

After playing your matching cards, place the matched pairs in the discard pile, face down. Then, to refill the center row, draw two cards from the draw pile and place them in the center. The center row must always have at least two cards.

DOS!

After playing cards from your hand, if you have two cards remaining, it’s time to shout “DOS” and end the game round. However, if you forget to announce “DOS” and another player catches you by calling “DOS,” you must draw two cards from the draw pile as a penalty.

DOS Scoring Rules

The round ends when a player discards all their cards. If they earned double color match bonuses during their turn, all other players must draw cards before scoring. The player who finishes first will earn points based on the cards remaining in the hands of the other players and will become the dealer for the next round.

Here are the rules for scoring points:

For example, if the winner discards all their cards and their opponents are left with the following:

• One DOS Wild card (20 points)
• Two numbered cards valued at 5 and 8 (total 13 points)
• One Wild # card (40 points)

The winner scores 73 points (20 + 13 + 40).

The first player to reach 200 points wins the DOS game, although this number can be adjusted if everyone agrees. Some versions of the game set the winning score at 500 points, but any number agreed upon by the group can be used.

Draw 4 Game Variation

In the Draw 4 variation, certain cards trigger penalties for your opponents. For example, when you play a Wild # card, the next player must draw four cards and skip their turn. This can slow down your opponent’s progress and give you a strategic advantage.

Similarly, the DOS Wild card can be used to force the next player to draw four cards if they fail to match a card. Timing is crucial, so use these cards wisely to put your opponents in a disadvantageous position.

Top 10 DOS Card Game Strategies to Follow

1. Play Low Cards Early: Start the game with low-numbered cards to reduce your opponents’ chances of making easy matches.
2. Save High Numbers for the Endgame: Keep high-value cards like 9 or 10 until the end to pressure opponents who have fewer cards left.
3. Save the Wild Cards: Hold on to Wild # and Wild DOS cards for later in the game when their potential is maximized. For example, keep a Wild # card that can act as any number until it’s needed to complete a match or block an opponent.
4. Watch Your Opponents’ Discards: The only clue you have to turn the game in your favor under DOS is keeping track of the cards your opponents discard. This helps you analyze their hand and plan your moves. For example, if your opponent discards a blue 6, you may want to keep a blue card in your hand in case they try to get rid of it.
5. Block Double Color Matches: Avoid situations where opponents can earn Double Color Match bonuses, as this could force you to draw cards.
6. Use Big Numbers Against Fewer Cards: If your opponent has only a few cards left, play high-numbered cards (like 9 or 10) to limit their matching options.
7. Maximize Color Match Bonuses: Take full advantage of Single Color Match and Double Color Match bonuses to force your opponents to draw cards while you stay ahead.
8. Always Call “DOS!”: Remember to call “DOS!” when you’re down to two cards to avoid penalties and stay in the lead. Stay vigilant.
9. Read Your Opponents’ Moves: Observe your opponents’ plays and discards to predict their next move and counter them. For instance, if your opponent keeps discarding a red card, they might have a lot of red cards. Now, play a color that is difficult for them to match.
10. Play Defensively: When in doubt, play a defensive game. Focus on reducing the chances of your opponents making matches or completing their turn rather than rushing to finish your own.
