Summary
Puzzle & Dragons (shortened to P&D or Pazudora (パズドラ)) was originally released in Japan on February 12, 2012. It is a with  monster-collecting  and  elements. It is the first ever mobile game to gross US$1 billion in revenue.

Gameplay
Players collect monsters (with individual monsters often referred to as "Cards" in English) through various means to create teams to take on Dungeons (ダンジョン) to win in-game currencies and more monsters. The puzzle element of the game takes place in the game's Dungeons where players move tiles called Orbs (ドロップ) on a 6-by-5 tile board within a time limit to make as many matches or Combos (コンボ) of three or more orbs of the same color that match with the monsters' elemental Attributes (属性): Fire, Water, Wood, Light, and Dark. If there are monsters on the player's team that have those Att., they can inflict damage on the Dungeon's enemy monsters; when 3 or 4 Orbs of the same Att. are matched only one enemy monster is hit with the attack, but if 5 or more are matched all enemies on the field are attacked. There are also Heal Orbs to recover HP and hazards such as Jammers that take up space, Poison and Mortal Poison Orbs that deduct the player's HP when matched, and Bombs that if not matched will explode to clear orbs on the board and deduct HP.

Monster Teams
A monster team comprises a monster designated as the Leader (リーダー), up to four monsters designated as Subs (サブ), and a Helper (助っ人) that is another player's team Leader. All monsters possess various stats such as Attack (ATK), HP, and Recovery (RCV), which increase when the monster gains experience to increase its level, either by clearing Dungeons or being fused with other monsters such as a certain class exclusively used for increasing experience.

The monster level generally scales from 1 to 99 with some monsters capable of having a Level Limit Break (レベル限界突破) increasing the level cap to 110 and then a Level Super Limit Break (レベル超限界突破) that further increases the level cap to 120. When monsters reach their max level they can Evolve (進化) to change their stats and abilities, with further Ultimate Evolutions (究極進化), Reincarnation Evolutions (転生進化), Super Reincarnation Evolutions (超転生進化), Pixel Evolutions (ドット進化), and Assist Evolutions (アシスト進化).

All monsters can also be given +Points to further buff the ATK, HP, and RCV stats to their maximum values. Monsters also possess Types (タイプ) that are either reflective of their general stat focus (Attacker, Physical, Healer, or Balanced), their design motif (God, Dragon, Devil, or Machine), or their utility as "items" (Evo Material, Awaken Material, Enhance Material, or Redeemable Material).

Skills
All monsters also possess various kinds of Skills (スキル). An Active Skill can be used by the player during a Dungeon with varying effects such as changing the Att. of Orbs on the board, directly inflicting damage to the enemy monster(s), buffing the player's team's stats, or recovering HP or other statuses such as various Binds; certain monsters also have a Skill Evolution (スキル進化) that changes the Active Skill for the remainder of the Dungeon and other monsters have skills that transform the monster itself for the rest of the dungeon with new stats, Skills, and other features.

A Leader Skill is a set of criteria the monsters in the Leader and Helper slots have that when matched improve the stats of the monsters on the team, such as applying an ATK multiplier if a certain number of the same Att. Orb are matched or a certain number of Combos are made in a single turn, buffing all cards of a specific Type or Att., reducing damage received for the next turn, or applying additional damage at the end of the turn.

Awoken (覚醒) Skills are a combination of passive stat multipliers and Orb-matching criteria that individual monsters on the team have to buff themselves unique from the Leader Skill such as the Two-Pronged Attack (2体攻撃) that multiplies ATK and hits two enemy monsters at once when 4 Orbs of the same Att. are matched or the [L] Increased Attack (L字消し攻撃) that multiplies ATK and removes the Lock status from Orbs on the board. While identical monsters will possess the same Awoken Skills, Latent (潜在) Awoken Skills can be applied to monsters to give them custom additional Awoken Skills and Super Awoken (超覚醒) unlocked after the Level Limit Break to have one of a set of additional Awoken Skills that are obtained at random by spending +Points on a monster who has already reached the +Point cap of +297.

Monsters can also be set as Assists (アシスト) which adds that monster's Active Skill as an additional Active Skill available to the base monster as well as improving stats based on the Assist's stats; monsters that have undergone Assist Evolution are granted the Awoken Assist Awoken Skill that append their Awoken Skills to the base monster when set as an Assist.

Dungeons
There are 6 types of Dungeons in the game: Normal, Technical, Special, Ranking, Quest, and Story Dungeons.

Normal Dungeons are the first set available to players, and enemy monsters simply attack the player monster with set damage outputs.

Technical Dungeons are unlocked after clearing a certain tier of Normal Dungeons, and feature enemy monsters possessing their own skills to hamper the player as well as having varying damage outputs depending on their own HP.

Special Dungeons are a set of rotating Dungeons that change either daily, hourly, or weekly and feature the Descended (降臨) series featuring one-off rare monsters that can be obtained after clearing the Dungeon.

Ranking Dungeons test players' skills against each other, earning points based on how they cleared the Dungeon such as time elapsed, number of turns taken, and certain special skills used with the top players of the whole server earning a Crown icon next to their in-game name. A subset of Ranking Dungeons are called Fevers and use a mechanic that incorporates a mechanic from Puzzle & Dragons W that gives players a limited amount of time to make as many combos as possible and earn as much points as possible by playing the level as long as possible, with only certain Att. Orbs dealing damage to the enemy monster which changes each run; points and overall player rank are cumulative, with players encouraged to reach the point cap. Quest Dungeons are a monthly rotating set of Dungeons of increasing difficulty, with clearing individual Dungeons and whole blocks of the Quest Dungeons rewarding players unique items.

Story Dungeons integrate a story with preset teams and enemy battles, with unique Evolution Material monsters awarded to players who clear the whole Story. There is also a Multiplayer mode featuring a 2-Player Mode for cooperative play of all Special and Technical Dungeons, a 3-Player Mode for cooperative play on a mix of permanent Dungeons and rotating Descended or Event Dungeons, and an 8-Player Mode for PVP in preset dungeons not unlike the Ranking Dungeons. A subscription model called P&D Pass also exists, giving players special Dungeons for each day of the month for additional in-game items as well as permanent access to all of the Descended Dungeons and daily Evolution Item Dungeons. Dungeons the player cost Stamina (スタミナ) to run, which recharges 1 point per 3 minutes or it can be completely restored through either microtransactions or in more recent years watching an in-game advertisement.

Progression
Monsters in the game have various inspirations from generic fantasy monsters such as goblins, ogres, slimes, and dragons to being inspired by various real world mythologies, religions, and historical figures. Monsters are variably obtained through winning them in Dungeons or winning them through the Egg Machines (ガチャ) by spending Magic Stones (魔法石) obtained through either clearing Dungeons, special events, or ; monsters can also be obtained through the Monster Purchase (モンスター購入) store with a Monster Points currency obtained by selling monsters or trading in monsters at the Monster Exchange (モンスター交換所).

Players are encouraged to use the Egg Machines during special twice-monthly events called God Fests (ゴッドフェス) where certain monsters that can only be obtained through the Egg Machine are made available, including many monsters only accessible during the event. Certain other themed Egg Machine events also happen throughout the year with some themed to holidays such as Halloween and Christmas or unique themed sets of original characters such as the Dragonbounds & Dragon Callers event which features an original storyline.

Puzzle & Dragons also has special Collaboration (コラボ) events which feature characters from various third-party intellectual properties such as other video games, anime, manga, and movies. These special events often feature monsters that when obtained by the player can unlock additional customizations to the game, such as Orbs Skins (きせかえドロップ) to change the appearance of the Orbs on the board and BGM Sets (BGMセット) that allow the player to customize the background music in Dungeons.
