What you are trying to do
Your main goal is to be the first player to get rid of all the cards in your hand. On your turn you will match cards from your hand to the cards in the play area by number or by combining cards so they match a target. Play passes around quickly, so think ahead and watch what others can play.
What you need and how to set up
Use only the cards and pieces that came with your copy of DOS. Different printings or retail bundles sometimes change a few cards or wording. Check the official rules that came in the box or the publisher’s site for the exact version your group has.
- Shuffle the game cards and deal each player the starting hand as the box rules say.
- Place the rest of the deck face down as a draw pile.
- Create the play area in the middle with the required number of face-up cards (follow the in-box setup for your edition).
- Decide who goes first by any simple method: youngest player, roll a die, or draw for highest number.
How to play
- On your turn, look at the cards in your hand and the cards in the center play area. You may play cards that match numbers shown there.
- You can usually play a single card that matches a card in the center or play multiple cards that together match a center card’s number. Exact match rules may vary by edition, so follow your box rules for the allowed combinations.
- If you play cards to match a center card, replace or update that center card as the game version requires so future players have new targets.
- If you cannot or choose not to play, draw the number of cards the rules require. Your turn then ends unless the version allows a follow-up play after drawing.
- Some cards or rules may let you change the center, skip players, or play wilds. Use those only as the cards and your edition’s rule sheet state.
- When you are down to a small number of cards, you must follow the alert or call procedure the rulebook sets for your copy of DOS. House rules can also be used if everyone agrees before you start.
How a round or game ends
A round usually ends when a player plays all their cards. Many groups play several rounds and total points, but scoring details vary by edition and are version-dependent. Check your in-box rules or the publisher’s official rules for exact scoring and any penalties for missed calls.
Beginner tips
- Watch the center cards and plan combos a turn ahead. That helps you use more cards at once.
- Keep an eye on opponents’ card counts. If someone is low, prioritize plays that slow them down.
- Agree on house rules before you play, especially about penalties, scoring, and any custom calls like saying "DOS."
- Play a practice round first so everyone learns your copy’s exact wording and special cards.
- For family-friendly penalties, use simple non-consumption consequences (like a small task) rather than anything involving substances.
FAQ
Do I need a special deck to play?
No. Play DOS with the cards and parts that come in the box for that game. Different retail bundles may include the game with other titles, but you don’t need a standard 52-card deck.
What if I forget to call my “two-card” warning?
Many versions of DOS require a verbal warning when you reach two cards. Penalties for forgetting are set by the official rules for your edition, so check the rule sheet in the box or the publisher’s site and decide as a group before playing.
Can kids play DOS?
Yes. DOS is family-friendly and works well for kids who can add and match numbers. Play a few practice rounds with simpler house rules if younger players need extra time to learn.
