Yu-Gi-Oh! is a card game where players aim to defeat their opponents by reducing their Life Points to zero. There are several rules to learn before starting. This article will help you understand the essentials before playing.
Steps
Learn about the cards

Monster Cards: Monster cards are summoned to attack, decrease the opponent's Life Points, and protect your own. Typically, monster cards are orange (Effect Monsters) or yellow (Normal Monsters), though other colors exist. Monsters have levels from 1 to 12 (indicated by stars at the top) and an attribute symbol in the top right corner. Above the description text, the Monster's Type (such as Tuner or Flip) and its abilities are highlighted. ATK refers to the attack points (abbreviated as Attack), and DEF refers to the defense points (abbreviated as Defense) located at the bottom of the card.
- Effect Monsters have abilities that affect the game, whereas Normal Monsters only have a brief description. Effect Monsters are widely used due to their powerful effects, while Normal Monsters are less strong but can serve useful roles in certain deck types. Monsters in the Extra Deck without effects are called Non-Effect Monsters. They are neither Normal nor Effect Monsters.
- Token Monsters are summoned via effects and can be placed in either attack or defense positions. Tokens are not part of any deck and can only be placed face-up on the field. They cannot be sent to the Graveyard, banished, flipped, or used as Xyz Materials. Tokens are considered Normal Monsters with attributes, ATK, DEF, Level, and Type defined by the card summoning them. Official Token cards are gray.
- Fusion, Synchro, Xyz, and Link Monsters are not present in your hand or Main Deck; they must be placed in the Extra Deck. Xyz Monsters have a black background and Rank instead of Level. Synchro Monsters have a white background, Fusion Monsters are purple, and Link Monsters have a green background and hexagonal design. Each of these monsters requires a specific summon method, typically Special Summon, before they can be summoned in other ways (such as being revived from the Graveyard). Some monsters have specific requirements for the materials used to summon them, listed in the first line of the card’s description.
- Ritual Monsters are blue and can only be summoned through Ritual Summon. Most of these monsters require a Ritual Spell Card for their summon.
- Pendulum Monsters can be any type of monster, with a background that shifts to green near the bottom, indicating its spell effect. The Pendulum Effect is noted above the description, with a Pendulum Scale on the sides. Pendulum Monsters can be activated from the hand like Spell Cards when placed in the Pendulum Zones, located at the far left and right of the Spell/Trap Zone. Unlike Field Spells, Pendulum Cards cannot be replaced by another Pendulum Monster in the same zone. When a Pendulum Monster is sent from the field to the Graveyard, it is placed face-up on top of the Extra Deck, ready to be summoned again. If there are Pendulum Monsters in both Pendulum Zones, Pendulum Summoning can occur (we will discuss this further later).
- Monster abilities include Tuner, Spirit, Gemini, Flip, Union, and Toon. Tuner Monsters are required for Synchro Summoning. Other abilities function as their names suggest.

Summoning: Summoning is the process of placing a monster onto your field. There are three main types of summons: Normal, Special, and Flip. A Normal Summon can be performed once per turn, while Special Summons have no such limit. You can Normal Summon a monster from your hand either face-up in Attack Position or face-down in Defense Position (known as a Normal Set). Monsters with 4 stars or fewer do not require a tribute, but for monsters with a higher star level, you must send one or more of your monsters from the field to the Graveyard. Monsters with 5 and 6 stars require one tribute, while monsters with 7 stars or more require two tributes. A Normal Summon that involves a tribute is referred to as a Tribute Summon.
- Your opponent cannot know what a face-down monster card is. When a card is placed face-down, it does not have a name, Attribute, or stats. It can only be flipped face-up by switching to Attack Position manually (known as a Flip Summon), via an effect, or when it is attacked. A flipped-up monster cannot be turned face-down unless by an effect.

Special Summon: A Special Summon is performed through a card effect or by following a game mechanic. Typically, monsters cannot be Special Summoned face-down, but they can be Special Summoned either in Attack or Defense Position. Below are some examples of Special Summons:
- Fusion Summon is typically performed using a Fusion Spell Card (such as Polymerization) and sending the listed monsters to the Graveyard as Fusion Materials. Some Fusion Monsters do not require a Fusion Spell Card and are called Contact Fusion (informally). Fusion Materials are usually specified quite clearly.
- Synchro Summon involves sending a Tuner monster and one or more non-Tuner monsters from your field to the Graveyard, then Special Summoning a Synchro Monster from your Extra Deck with a level equal to the sum of the materials’ levels.
- Xyz Summon can be performed by stacking two or more monsters from your field with the same level on top of each other and then placing an Xyz Monster with the same Rank on top. The monsters underneath are considered Xyz Materials and are no longer on the field. Most Xyz Monsters have effects that can be activated by detaching Xyz Materials (sending them to the Graveyard). If an Xyz Monster leaves the field or is no longer treated as a monster, its Xyz Materials will be sent to the Graveyard.
- Ritual Summon is typically done using a Ritual Spell Card, sacrificing monsters whose combined level matches the Ritual Monster's level, then Special Summoning the Ritual Monster from your hand. Of course, there are exceptions – always read your Ritual Spell Card's description for details.
- Pendulum Summon can be performed if you have Pendulum Monsters in both Pendulum Zones. You may Special Summon as many monsters from your hand or from face-up in your Extra Deck whose level is higher or lower than the Pendulum Scales (levels cannot be equal to the Pendulum Scales). You can perform a Pendulum Summon once per turn.
- Link Summon is performed by sending monsters from the field to the Graveyard as Link Materials to meet the requirements of a Link Monster. You must use the number of materials equal to the Link Rating (shown in the bottom-right corner). If a Link Monster is used as a Link Material, it can be considered a single monster or the number of materials equal to its Link Rating. Link Monsters do not have a level or defense, and cannot be placed in Defense Position. You will see orange arrows surrounding the Link Monster card, where the number of arrows equals its Link Rating, pointing to Monster Zones around the field. Monsters in the Extra Deck can be summoned to zones that the Link Monster’s arrows point to.

Extra Monster Zone: Introduced with Link Monsters in Master Rule 4, there are two Extra Monster Zones on the field, connected between both players’ fields. Any summon from the Extra Deck must be placed in one of these Extra Monster Zones. Anything that is not a summon from the Extra Deck, such as banishing temporarily, changing ownership, or returning to the field after a change of ownership, must be placed in the Main Monster Zone. Once a monster is summoned to one of the Extra Monster Zones, it remains under your control for the rest of the duel. The remaining Extra Monster Zone naturally belongs to your opponent.

Spell Cards: Spell Cards are green in color and typically activated from your hand during your turn. They come with a variety of effects. There are six types of Spell Cards, and non-Normal Spells are marked with an icon at the top-right corner near the bolded text to indicate the card type.
- Normal Spell Cards are played from your hand to the Spell/Trap Zone, and once their effects are resolved, they are sent to the Graveyard.
- Continuous Spell Cards are marked with an ∞ symbol. After being activated on the field, they remain in play unless removed, with their effects continuing to apply as long as they remain on the field.
- Quick-Play Spell Cards are marked with a lightning bolt icon. These can be used at any point during your turn, and even during your opponent's turn if set face-down.
- Field Spell Cards, represented by a dartboard symbol, are placed in the Field Spell Zone when activated or set face-down. Field Spells affect the entire field and remain in play unless removed. If another Field Spell is activated while one is already in play, the older Field Spell is destroyed. Both players can have a Field Spell in play at the same time.
- Equip Spell Cards, denoted by a plus symbol, are activated and equipped to a face-up monster on the field, remaining on the field until removed. Equip Spells are destroyed if the monster they are equipped to is no longer face-up or is no longer a valid target.
- Ritual Spell Cards, featuring a flame symbol, are used to perform Ritual Summons. These work like Normal Spells and typically require you to sacrifice monsters on the field to summon the desired Ritual Monster from your hand.

Trap Cards: Trap Cards are used during your opponent's turn to interrupt their plays. They are purple in color and marked with an icon in the corner if they are not Normal Trap Cards. All Trap Cards must be Set (placed face-down in the Spell/Trap Zone) before they can be used, and they can be activated during either player's turn.
- Normal Trap Cards can be flipped face-up when you want to activate them, and once their effect is used, they are sent to the Graveyard.
- Continuous Trap Cards have the same ∞ symbol as Continuous Spells and function in a similar way.
- Counter Trap Cards, indicated by an arrow symbol, are like Normal Trap Cards but can only be countered by other Counter Trap Cards.
Gameplay Mechanic

Setting Spells and Traps: Spell and Trap Cards can be Set from your hand during the Main Phase. When Set, they are placed face-down in the Spell/Trap Zone. If you Set a Trap Card or a Quick-Play Spell, they cannot be activated until your next turn.

Battle: If your monster is in Attack Position during the Battle Phase, you may use it to attack your opponent's monster. If your opponent has no monsters on the field, you may directly attack their Life Points. Each monster can only attack once per turn. If a monster attacks a face-down card, it will be flipped face-up immediately before damage calculation.

Damage Calculation:
- If both monsters are in Attack Position, the monster with the lower ATK will be destroyed, and the owner of that monster will lose Life Points based on the difference in ATK.
- If the ATKs are equal, both monsters are destroyed.
- If the defending monster has a DEF lower than the attacking monster's ATK, it will be destroyed, but the defender's Life Points remain unaffected.
- If the defending monster has a higher DEF than the attacker's ATK, the attacker will lose Life Points based on the difference in damage, but no monsters are destroyed.
- If the ATK and DEF are the same, neither monster is destroyed.
- When directly attacking Life Points, the opponent suffers damage equal to the attacking monster's ATK.

Replay: During your attack, if the number of your opponent's monsters changes, a replay occurs. In this case, you can choose to continue attacking with the same monster, switch to another monster, or forgo the attack entirely. You may also change your attack target. If you choose a different monster, the original one is considered to have already attacked and cannot attack again for the remainder of the turn.

Battle Positions: Monsters can be placed in Attack Position or Defense Position. Their position determines which stat is used for damage calculation; high-ATK monsters should be in Attack Position, while low-ATK monsters should be in Defense Position. If an opponent's monster has a higher ATK than any of your monsters, you should place your monsters in Defense Position to protect your Life Points. Battle Positions can be changed once per turn for each monster during your Main Phase. You cannot change a monster's position if it has been summoned, set face-down, or has already attacked during that turn.

Chain: A Chain is a series of card activations or effects where one is activated before another effect can resolve or apply. Activating a card or effect creates a Chain Link. Once activated, the opponent may respond with their own card, creating Chain Link 2. This continues until both players stop responding, after which the chain resolves starting from the most recent Chain Link. During the resolution of a Chain, no further cards or effects can be activated.
- Example: Player A activates 'Torrential Tribute,' creating Chain Link 1. Player B responds with 'Seven Tools of the Bandit' to negate 'Torrential Tribute' by paying 1000 Life Points. The cost is paid during activation, not resolution. Player A does not activate any further cards, nor does Player B. The Chain now resolves, starting with 'Seven Tools.' 'Seven Tools' negates 'Torrential Tribute,' and no monsters are destroyed.

Spell Speed: Only Quick-Play Spells, Trap Cards, and Quick Effects can be Chained with another card to form Chain Links 2 or higher. A Quick Effect is explicitly stated as such or can be activated during any player's turn, including the opponent's turn. The effect must be a Spell Speed 2 or higher, or a Trigger effect that can activate outside your Main Phase. Quick-Play Spells can only be used in the opponent's turn if set in the previous turn. If a Counter Trap is activated, the only card that can be Chained is another Counter Trap.

Extra Link: Extra Link is a strategy that involves using Link Monsters to take control of your opponent's Extra Monster Zone. To achieve this, you need to connect your Link Monsters (with arrows pointing toward each other) from your Extra Monster Zone to your opponent's Extra Monster Zone. Once the condition is met, you can summon a Link Monster into your opponent's Extra Monster Zone, co-linked with your own, and the zone will be under your control as long as the Link Monster remains there. Link Monsters can be summoned in U-shape, diagonal, or V-shape patterns. You can even use monsters controlled by your opponent to complete the Extra Link. If your opponent has three co-linked monsters in their Main Monster Zone, summoning two Link Monsters into the Extra Monster Zone, co-linked with these monsters, will complete the Extra Link.
Card Duel

Building Your Deck: To play Yu-Gi-Oh, you must have a deck. Your deck must contain between 40 and 60 cards, but it's generally better to keep it at 40 or slightly more. Your deck should have a balance between monsters, spells, and traps. A good ratio is around 15-20 monsters, 9-12 spells, and 5-8 traps. However, this isn't a strict rule, and you can adjust it depending on your understanding of deck building. In reality, these numbers don't matter much in actual gameplay. Most monsters should be level 4 or lower, with only a few high-level monsters that cannot be summoned by other means. Spell and Trap cards should cover your deck's weaknesses, and your deck should include cards that fall into several categories: attack protection, effect negation, summon negation, and spell/trap destruction. Of course, these numbers are not absolute, and they can vary based on your deck. Your deck will perform better if it focuses on a specific theme or archetype.
- Your Side Deck isn't required for regular play, but it is useful for most decks. Fusion, Synchro, and Xyz monsters are placed in the Side Deck rather than the Main Deck. You can view your Side Deck at any time during the game, and you can Special Summon monsters from it during your turn. The Side Deck can contain up to 15 cards. Your opponent cannot view your Side Deck unless an effect allows them to.
- The Side Deck also has a maximum of 15 cards. It is not required, but it is suitable for tournament play. A match consists of three games, and the player who wins 2 out of 3 games is the overall winner. The Side Deck contains cards used to counter popular decks or to exploit your opponent's weaknesses, but cards that would disrupt your deck's consistency are not appropriate. The Side Deck is not used during the match but can be used to replace cards in your Main or Side Deck between games. After replacing the cards, your Side Deck must still contain the same number of cards as it did originally.
- You are only allowed to have three copies of the same card in your Main Deck, Side Deck, and Extra Deck combined. Some cards are banned or limited in tournament play, so make sure your deck is legal if you plan to participate in a tournament.

Starting the Duel: To begin a duel, find someone to play with. Shuffle your decks and decide who will go first. This can be decided by rock-paper-scissors, flipping a coin, or any other suitable method. The player going first cannot draw cards or attack. Decks that can set up their field early or use effects to avoid normal battles typically benefit from going first, while decks that rely on having additional cards in hand to respond to the opponent's actions often prefer going second. Both players start the duel with 8000 Life Points.

Place Your Cards in the Correct Zones: Place your Side Deck at the bottom-left of your play area, your Main Deck on the bottom-right, and leave space in the middle to place up to 5 cards. This space will be your Spell/Trap Zone. Above your Main and Side Decks are the Pendulum Zones, one on the left and one on the right. The top row contains the Field Spell Zone on the left and the Graveyard on the right. The five empty spaces in the middle are your Monster Zones. The Banished Zone is typically located to the right of your Graveyard.

First Draw: Both players will draw 5 cards at the start of the duel to begin the game.
- Only you can see the cards in your hand, not your opponent. The opponent can only view your hand when a card effect allows it. It's crucial to keep your hand secret to prevent your opponent from predicting your strategy. In the End Phase, if you have more than 6 cards in your hand, you must discard until you have exactly 6 cards remaining.

Drawing a Card: At the start of your turn, during the Draw Phase, you will draw one card from your deck. The player going first cannot draw a card immediately.

Entering the Standby Phase: Certain effects may be activated during the Standby Phase. If no such effects occur, this phase is skipped.

Proceed to the Main Phase: The Main Phase is the most crucial part of your turn, where you'll perform most of your actions. During this phase, you can summon monsters, activate effects, change the battle positions of your monsters, and activate or set spells and traps.

Battle: You can attack with monsters in Attack Position during the Battle Phase. Entering the Battle Phase is not mandatory. If you choose not to enter the Battle Phase, you can proceed to the End Phase and skip Main Phase 2. The player going first cannot enter the Battle Phase immediately.

Enter Main Phase 2: After the Battle Phase, you move into Main Phase 2. During this phase, you can perform similar actions to Main Phase 1, with the exception that you cannot change the battle position of a monster that has already attacked during the Battle Phase. You cannot enter this phase unless you've already gone through the Battle Phase.

End Your Turn: The End Phase concludes your turn. Certain effects may be triggered during this phase, and once it is over, the turn passes to the other player.

Continue the Duel Until One Player Loses: A player loses if their Life Points reach 0. If a player must draw a card but has no cards left in their deck, they also lose. Additionally, players can win or lose due to card effects.
Tips
- A simple way to play Yu-Gi-Oh! is by using an online emulator. This free method allows you to test various decks and compete with players worldwide. YGOPro (and related mods) can be downloaded from their Discord server, while Dueling Book is browser-based, requiring manual setup to ensure proper gameplay.
- Duel Links (mobile game) is a free and easy way to play Yu-Gi-Oh. It's not the modern Yu-Gi-Oh, but a slower, classic version that may appeal to some players.
- You can calculate Life Points using a calculator or pen and paper.
- Life Points can exceed 8000 due to card effects.
- Plan your moves in advance and try to predict your opponent's strategy.
- Familiarize yourself with your cards to speed up gameplay.
- If there's a specific card you need, it’s often cheaper to buy it individually online rather than opening multiple packs and hoping to pull it.
- Cards drawn from your deck must be revealed to your opponent.
- All Trap effects are Spell Speed 2, including Graveyard effects and hand effects.
- For more detailed and up-to-date information, visit the Yu-Gi-Oh Wiki or the official website.
Warning
- While dueling, avoid "stacking your deck." "Stacking your deck" is a form of cheating where you arrange your cards in advance to ensure you draw the exact card you need at the perfect moment. If caught during an official tournament, you will DEFINITELY be disqualified. Additionally, when facing an experienced player, this trick rarely works.
- This card game can become quite expensive, especially if you're aiming to compete at a serious level.
