Every Yu-Gi-Oh! turn runs through six phases in the same order, and you can’t go back to an earlier one. Knowing what belongs in each phase saves you from misplays.
1. Draw Phase
The turn player draws 1 card. If you can’t draw because your Deck is empty, you lose. The player who goes first doesn’t draw on their first turn.
After the draw, either player can activate Traps and Quick-Play Spells before the game moves to the Standby Phase.
2. Standby Phase
Some cards have effects that happen, or costs you must pay, during the Standby Phase. If you have none, nothing happens here, but players can still activate Traps and Quick-Play Spells before you move on.
3. Main Phase 1
Most of your plays happen here, in any order you like:
- Normal Summon or Set a monster — once per turn, including Tribute Summons.
- Special Summon and Flip Summon — no limit.
- Activate cards and effects — as many as you can pay for.
- Set Spells and Traps — as long as you have space.
- Change battle positions — but not for a monster that was played onto the field this turn, or that you’ve already changed this turn.
4. Battle Phase
You don’t have to battle, and the player who goes first can’t conduct a Battle Phase on their first turn. The Battle Phase has four steps:
- Start Step: announce “I’m entering the Battle Phase.”
- Battle Step: choose one of your monsters to attack and a target. If your opponent has no monsters, you can attack directly. Each face-up Attack Position monster gets one attack per turn.
- Damage Step: the battle is resolved and damage is dealt. Only certain cards can be used here (see the damage step).
- End Step: announce that your Battle Phase is over.
You repeat the Battle Step and Damage Step for each attack.
Replays: if your opponent’s monsters change after you declare an attack but before the Damage Step (for example, the target leaves the field), you can attack again with the same monster, attack with a different one, or not attack. If you switch to a different monster, the first one still counts as having attacked.
5. Main Phase 2
You can do everything you could in Main Phase 1, except things you’ve already used up, like your Normal Summon. A monster that attacked can’t change its battle position in Main Phase 2. The rulebook suggests using this phase to prepare for your opponent’s turn based on how the battle went.
6. End Phase
Announce the end of your turn. Cards that say “during the End Phase” resolve now. If you have more than 6 cards in hand at the end of this phase, discard until you have 6.
Moving between phases
The turn player gets the first chance to act in every phase and step. Announcing the end of a phase means you’re passing that chance to your opponent, and they can say “before the end of your phase, I activate this card.” Saying your phase changes out loud (“Standby Phase”, “Main Phase”, “Battle Phase”) gives your opponent clear windows to respond and avoids disputes.
Common mistakes
- Forgetting Main Phase 2. If you skipped your Normal Summon in Main Phase 1, you can still use it after battling.
- Attacking on the first turn. The player who goes first can’t conduct a Battle Phase that turn.
- Changing position on the turn you summoned. Not allowed.
- Changing position after attacking. A monster that attacked can’t change position in Main Phase 2.
- Rushing through phases. Your opponent is allowed to respond before each phase ends.
