Yu-Gi-Oh! Forbidden Memories Gameplay

The mechanics of this game differ from '''Yu-Gi-Oh! Trading Card Game', and these differences are also contiguous with the PS2 game Yu-Gi-Oh! The Duelists of the Roses'', but are not the same. The main differences are:
 * All Monster Cards in this game are Normal Monster Cards.
 * With the exception of ritual summons, you are not required to tribute monsters to summon Level-5 or higher monster.
 * A card can placed face-up or face-down, in attack or defense mode. Hence, a monster can be played in face-down attack mode.
 * The player cannot control the activation of his/her Trap Cards. A trap will activate as soon as its conditions for activation are met.
 * A deck must be made up of exactly 40 cards.



The following example is used in the manual: "when "Gaia the Dragon Champion" (AP:2600) chooses Mercury and attacks "Blue-Eyes White Dragon" (AP:3000 and in attack position), "Gaia" has his AP increased to 3100, making it possible to defeat "Blue-Eyes White Dragon".
 * At the start of the player's turn, he/she draw from his or her deck until his/her hand consists of five cards; if the deck cannot, the player loses the duel.
 * The player must play at least one card to the field after drawing.
 * Cards can be "fused" in the hand without the card Polymerization; the player can fuse any amount of his/her cards together and in any order, but the chance of a "successful" fusion (where a new monster or spell or trap is made, or when a monster is strengthened) depends on the cards the player is fusing.
 * When any spell or trap card is fused with a monster that is not compatible, the spell or trap card is discarded and the monster is unaffected.
 * After fusion, cards can be played face-up or face-down. Traps that are played face-up are not activated until their condition is met.
 * Monster Cards must select one of two "Guardian Stars", which allow a monster to gain five hundred attack and defense points if it has chosen a superior alignment against its opposing card; these alignments are taken directly from cosmic bodies and are arranged as follows (> means "is superior to"):
 * Mercury > Sun > Moon > Venus > Mercury
 * Mars > Jupiter > Saturn > Uranus > Pluto > Neptune > Mars
 * The Guardian Stars selected represent the Attribute and the Type of the monster. In the 3-D battle sequence the attack the monster uses depends on the guardian star selected. For example when you summon Meteor B. Dragon you are given the choice of Sun or Mars. Choosing Mars will cause Meteor B. Dragon to use a Fire Attack and give it an attack bonus against Jupiter (typically plant-type) monsters. If the player chooses Sun instead, "Meteor B. Dragon" will use a Light Attack with an attack bonus against the Moon.
 * Mercury typically represents Dark Spellcasters and Dark Warriors.
 * Sun typically represents Light monsters, specially Fairies.
 * Moon typically represents Dark monsters, specially Fiends and Zombies.
 * Venus typically represents "Illusory" monsters (most of them are Spellcasters, Fiends or Fairies)
 * Mars typically represents Fire monsters.
 * Jupiter typically represents Forest creatures, such as Beasts, Beast-Warriors, Insects and Plants.
 * Saturn typically represents Wind monsters
 * Uranus typically represents Rock monsters and Earth Warriors.
 * Pluto typically represents Machines and Thunder-type monsters.
 * Neptune typically represents Water monsters.
 * During the battle phase, after attacking and before damage is calculated, pressing square will take the player to a polygonic action battle screen.
 * Cards that cannot be used at that time are darkened (once a monster has attacked, its card darkens.)
 * Pressing start will end the player's turn.
