Question 1

How many cards are in Forbidden Memories?

Accepted Answer

There are 722 cards in Yu-Gi-Oh! Forbidden Memories, spanning Monster, Magic, Trap, Equip, and Ritual card types. Of those, 689 are obtainable through normal gameplay — drops from specific duelists, fusions, passwords, ritual summons, and the initial deck. The remaining 33 cards cannot be obtained through normal means. Most of them exist in the game's data and can technically be purchased via Password for 999,999 Starchips each — an amount that requires an extreme amount of farming. However, 2 cards (Dark Magic Ritual and Magician of Black Chaos) are completely unobtainable, with no password, no drop source, and no fusion method available in any version of the game outside Japan.

Question 2

How do I obtain cards?

Accepted Answer

There are several ways to get cards for your collection in Forbidden Memories: Duelist drops — each duelist drops specific cards based on your performance rank (POW or TEC) and rank tier (S, A, B, C, or D). Different rank groups (S/A TEC, S/A POW, B/C/D) give different rewards., Password — almost every card has a password that can be entered in the Password menu. Cards cost Starchips ranging from 200 to 999,999., Initial deck — you start each playthrough with a randomized deck of 40 cards from a fixed pool. Each duelist has a drop table. You can check which cards a duelist drops and at which rank requirements on their dedicated page.

Question 3

How do I search for a card?

Accepted Answer

The search bar at the top performs real-time filtering across multiple fields simultaneously: card name, ID number (001–722), ATK and DEF values, monster type, and card type. Typing '3500' instantly shows every card with 3500 ATK (like Meteor B. Dragon), Typing 'Dragon' filters to Dragon-type monsters, Typing 'Equip' shows all Equip cards The list narrows as you type with no page reload needed. View Meteor B. Dragon (#713) details - /cards/meteor-b_-dragon

Question 4

How do the card filters work?

Accepted Answer

The filter controls sit below the page title and work together with the search bar. Every filter is a toggle — click once to enable it, click again to disable it. Multiple filters stack at the same time using AND logic: a card must match every active filter to appear in the results. Active filters are highlighted with a colored border so you always know what’s enabled. The available filters let you narrow down by card type (Monster, Equip, Magic, Trap, or Ritual), by monster type (Dragon, Spellcaster, Warrior, Fiend, and every other type present in the game), and by stat thresholds — Strong (ATK 2000+) and Defensive (DEF 2000+). Each filter button shows a percentage of how many cards match it, helping you gauge how broad or narrow each filter is before enabling it. You can also filter by group using the filter button. Groups are curated collections like ‘High ATK’ or ‘Dragons’, including any custom groups you’ve created on the deck page. The search bar at the top ties everything together, letting you type any name, ID, or stat value for real-time results alongside your active filters.

There you’ll find the complete reference: Full ATK/DEF stats, card type, monster type, and star level, The original PS1 description text and card artwork, Both guardian stars with their strengths and weaknesses, Field terrain advantages — which fields boost or reduce the card’s stats, Every known fusion recipe (both as fusion material and as fusion result), Compatible equips that can be equipped to the card, Which duelists drop the card, at which rank requirements and drop rates, Interactive guardian star matchup charts to compare against other cards See an example: Dark Magician (#002) detail page - /cards/dark-magician

Question 6

What are Guardian Stars?

Accepted Answer

Every monster in Forbidden Memories has two Guardian Star signs, chosen from Sun, Mercury, Venus, Moon, Mars, Jupiter, Saturn, Uranus, and Neptune. During battle, your monster's Guardian Stars determine type advantage or disadvantage against the opponent's monster. Each star is strong against one sign and weak against another. During battle, you choose one of your monster's two guardian stars. If your chosen star is strong against the opponent's, your monster gains +500 ATK and DEF. If your star is weak against the opponent's, the opponent gains +500 ATK and DEF instead. Explore the interactive Guardian Star chart - /guardians

Question 7

How does fusion work?

Accepted Answer

Fusion is the core mechanic of Forbidden Memories. During a duel, you can select 2 to 5 cards from your hand, or 2 to 6 if you include a monster already on the field. You can also select a card from your hand and fuse it to a card on the field by placing the result where the field monster was — that’s why you can select up to 6. Similarly, you can fuse a Magic, Trap, Equip, or Ritual card with a card already in the backrow — the card activates immediately. The fusion happens two cards at a time in sequence, and the result can be used as material in the same fusion chain. All card types can be fused — monsters, equips, magic, traps, and rituals. Each card has specific fusion recipes stored in its data. Selecting two cards checks if the first card has a fusion entry for the second. For example, Curse of Dragon + Kaminari Attack produces Twin-headed Thunder Dragon, one of the most reliable monsters in the game. If no fusion exists, the second card replaces the first (or stays unchanged if an equip is involved).

Question 8

What do the different card types mean for gameplay?

Accepted Answer

Each card type behaves differently in a duel. Monster Cards There are 621 Monster Cards in Forbidden Memories, spread across 20 different monster types. Each monster has ATK and DEF stats and two guardian star signs that determine type advantage or disadvantage against other monsters during battle. Their monster type influences fusion recipes and determines which field spells provide terrain advantage (+500 ATK/DEF). The strongest monster in the game is Blue-Eyes Ultimate Dragon (4500 ATK / 3800 DEF), followed by Gate Guardian (3750 ATK / 3400 DEF). The most common monster type is Warrior (73 cards), while the rarest is Sea Serpent (5 cards). However, one of the most reliable strategies in the game revolves around Twin-headed Thunder Dragon (2800 ATK / 2100 DEF). It is the most fused monster in Forbidden Memories — the recipe is simple: Dragon + Thunder (as long as one has 1600+ ATK). It accepts 7 different Equip Cards (Megamorph boosts it to 3800 ATK, while the other 6 grant +500 each), making it a consistent powerhouse that can carry you through most of the game.

When attached to a monster, they boost its ATK and DEF — most grant +500, with Megamorph being the only exception at +1000. Each Equip Card can only be equipped to specific monster types. For example, Legendary Sword works with Warriors, Dragon Treasure with Dragons, and Beast Fangs with Beasts and Beast-Warriors. Equip Cards also appear as fusion material in certain recipes, such as Salamandra fusing with Flame Swordsman. Be careful when facing Reverse Trap: this trap card reverses power-up effects, turning equip bonuses into penalties. Most Equip Cards can be obtained as duelist drops from various opponents, and all 34 are available via Password.

Question 9

How do Drop Rates work in the table?

Accepted Answer

The Drop Rates section shows a matrix of every card vs. every duelist, with the exact percentage chance that the duelist will drop that card based on your performance in the duel. Each duelist has a drop pool of multiple cards, and the game selects 1 card from that pool after a duel. The probability of getting a specific card depends on how many copies of it are in the pool. The table calculates this as: (weight of the card in that rank group / pool size) × 100. Drop rates are split into three rank categories based on your duel performance: SA-POW — S or A rank with POW (Power) focus. Shown in red., SA-TEC — S or A rank with TEC (Technical) focus. Shown in blue., BCD — B, C, or D rank. Shown in yellow. Can be POW or TEC. The table is interactive: you can search for a card by name, ID, or stats using the search bar, or apply filters to narrow down by card type, monster type, or stat thresholds. Clicking a duelist's icon in the header takes you to their full detail page. Each cell shows up to three percentages (one per rank group) and hovering over a cell with your mouse reveals the full breakdown in a tooltip.
