How to Play Yu-Gi-Oh
A Yu-Gi-Oh Duel is a turn-based card game where each player uses Monsters, Spells, and Traps to reduce the opponent's Life Points from 8000 to 0. You build a Main Deck, optionally use an Extra Deck, then play cards to attack, defend, remove threats, and set up stronger turns. Once the basics make sense, the deck-building guide turns those rules into a playable list.
What you need to start
- Main Deck: 40 to 60 cards. Most competitive decks stay close to 40 so they draw key cards more often.
- Extra Deck: up to 15 Fusion, Synchro, Xyz, and Link Monsters. Not every deck needs all 15, but many do.
- Side Deck: up to 15 cards for tournament matches. You swap these between games, not during a single game.
- Card limit: normally no more than 3 copies of a card across your Main, Extra, and Side Deck combined, unless the TCG banlist says otherwise.
The basic turn order
| Phase | What happens |
|---|---|
| Draw Phase | Draw 1 card, except the player going first does not draw on the first turn. |
| Standby Phase | Resolve effects that specifically happen during the Standby Phase. |
| Main Phase 1 | Normal Summon, Set cards, activate most Spells, and start your main plays. |
| Battle Phase | Attack with monsters. The player going first skips the Battle Phase on the first turn. |
| Main Phase 2 | Set up after battle, summon if you still can, and place defensive cards. |
| End Phase | Resolve end-of-turn effects, then pass to the opponent. |
The three main card types
- Monsters fight, defend, and often carry the effects that make your strategy work. Some famous examples are Blue-Eyes White Dragon, Dark Magician, and Ash Blossom & Joyous Spring.
- Spells are usually played from hand on your turn, though Quick-Play Spells can also be Set and used on a later turn.
- Trapsare Set first, then activated after timing conditions are met. Most Traps cannot be activated the same turn they are Set, but they can punish the opponent's plays once live.
How you win
Most games end by dealing battle or effect damage until the opponent reaches 0 Life Points. Some cards can win by special conditions, and a player also loses if they must draw but have no cards left in Deck.
What to learn next
- Pick one strategy or archetype and learn what its cards are trying to do.
- Build a legal list once the core turn flow and card limits make sense.
- Check the current Yu-Gi-Oh TCG banlist, effective 2026-05-18, before playing in tournaments.
- Use card pages to confirm exact text, printings, and rarities before buying singles.
