This guide teaches you how to play Yu-Gi-Oh! from scratch: what a legal deck looks like, how the field is laid out, every phase of a turn, how summoning works, what Spells and Traps do and how to win. Whether you're new to card games or coming back after twenty years away, start here. Modern Yu-Gi-Oh! is faster than the game you remember, but the foundations haven't changed.
The goal of Yu-Gi-Oh!
Each player starts with 8,000 Life Points (LP). You win when:
- Your opponent's LP reaches 0
- Your opponent has to draw a card but their deck is empty
- A card's effect says you win (rare, but it exists)
Most games are won by battle damage and effect damage reducing LP to 0.
Yu-Gi-Oh! deck rules
| Deck | Size | What goes in it |
|---|---|---|
| Main Deck | 40–60 cards | Normal, Effect, Ritual and Pendulum Monsters; Spells; Traps |
| Extra Deck | 0–15 cards | Fusion, Synchro, Xyz and Link Monsters (plus face-up Pendulums during play) |
| Side Deck | 0–15 cards | Swapped in between games of a match |
You can have up to 3 copies of any card across all three decks, unless the Forbidden & Limited List restricts it. Read about the current list in our Yu-Gi-Oh! banlist guide. Most competitive decks run as close to 40 cards as possible, which makes your best cards more likely to show up.
The field
| Zone | Count | Use |
|---|---|---|
| Main Monster Zones | 5 | Your monsters |
| Extra Monster Zones | 2 (shared) | Monsters summoned from the Extra Deck, especially Link Monsters |
| Spell & Trap Zones | 5 | Set or active Spells and Traps; the outer two double as Pendulum Zones |
| Field Zone | 1 | Field Spells |
| Graveyard (GY) | — | Destroyed, used and discarded cards |
| Banishment | — | Cards removed from play |
Under current rules, Fusion, Synchro and Xyz Monsters can be summoned straight to your Main Monster Zones. Link Monsters and Pendulum Monsters from the Extra Deck need an Extra Monster Zone or a zone a Link Monster points to.
Starting the duel
- Shuffle your Main Deck and let your opponent cut it.
- Decide who goes first (rock-paper-scissors or a coin toss). The winner chooses.
- Each player draws 5 cards.
- The player going first doesn't draw on their first turn and can't conduct a Battle Phase on that turn.
How to play a turn: the six phases
| Phase | What happens |
|---|---|
| Draw Phase | Draw 1 card. |
| Standby Phase | Some card effects happen here. |
| Main Phase 1 | Summon monsters, activate cards and Set Spells and Traps. |
| Battle Phase | Attack with your monsters. |
| Main Phase 2 | Same as Main Phase 1, after combat. |
| End Phase | End-of-turn effects; discard down to 6 cards if you have more. |
Summoning monsters
Once per turn, you can Normal Summon (face-up attack position) or Set (face-down defence position) one monster from your hand:
- Level 1–4: no Tribute needed.
- Level 5–6: Tribute 1 monster you control.
- Level 7 or higher: Tribute 2 monsters.
Beyond that, there's no limit on Special Summons, which come from card effects and from the Extra Deck. Modern decks are built around chaining Special Summons into powerful Extra Deck monsters. Our Yu-Gi-Oh! summoning mechanics guide explains Fusion, Ritual, Synchro, Xyz, Pendulum and Link summoning.
Spells and Traps
- Spells can be activated from your hand during your Main Phase. Quick-Play Spells can also be activated on the opponent's turn if they're Set first.
- Traps must be Set first and can't be activated until your opponent's next turn (or later), unless a card says otherwise. Traps are your main way to interrupt the opponent.
Spells come in Normal, Quick-Play, Continuous, Equip, Field and Ritual types. Traps come in Normal, Continuous and Counter types.
Chains and spell speed
When cards are activated in response to each other, they form a chain. Chains resolve backwards: the last card activated resolves first. Each card has a spell speed that decides what it can respond to. Most monster effects and Spells are Speed 1 or 2, Traps and Quick-Play Spells are Speed 2, and Counter Traps are Speed 3. Hand traps are monsters you activate from your hand on the opponent's turn. They're a huge part of modern play. See our hand traps guide.
Battle
In the Battle Phase, each attack-position monster you control can attack once:
- Attack vs. attack position: the monster with lower ATK is destroyed and its controller takes the difference as damage. If they're equal, both are destroyed.
- Attack vs. defence position: if your ATK is higher than their DEF, their monster is destroyed with no damage. If it's lower, you take the difference.
- Direct attack: if your opponent has no monsters, your attack hits their LP directly.
How modern Yu-Gi-Oh! feels
If you last played in the 2000s, expect a bigger first turn. Many decks spend their opening turn Special Summoning several times to build a board of monsters with disruptive effects. The second player tries to break that board with hand traps and removal spells. Learning a deck's combo lines is now part of learning to play.
If you'd prefer a slower format, look at Genesys, Konami's points-based format that removes Link and Pendulum Monsters. See our Yu-Gi-Oh! Genesys guide.
