# Dragon Ball Z: Dokkan Battle

Dragon Ball Z: Dokkan Battle (Japanese: ドラゴンボールZ ドッカンバトル) is a free-to-play mobile game based on the Dragon Ball anime franchise. Developed by Akatsuki and published by Bandai Namco Entertainment, it was released in Japan for Android on January 30, 2015 and for iOS on February 18, 2015. Dokkan Battle was eventually released worldwide for iOS and Android on July 16, 2015. The game has exceeded 350 million downloads worldwide, and has grossed over $3 billion in worldwide revenue.

## Gameplay

The game includes elements of board game, collectible card game, and puzzle genres. The main game is made up of levels that work similarly to board games, with spots dedicated to items, power-ups, traps, and fights.

### Character Collecting

Dragon Ball Z: Dokkan Battle is a gatcha game, meaning to obtain many characters, the player must spend in-game currency to randomly summon and have a chance at getting a certain character. There are 6 rarities: N, R, SR, SSR, UR, and LR. Only N, R, SR, and SSR characters are obtainable through summoning; UR and LR characters are obtained through Dokkan Awakening. When a player obtains a character, they can Z-Awaken and Dokkan Awaken the character by obtaining awakening medals, and leveling up the character through training. These characters can be used during fights, and different characters have different abilities.

#### Types of Banners

There are multiple types of banners to summon on and obtain characters from. Dokkan Festival banners give new, premium characters, which mostly awaken into a UR, but rarely awaken in an LR during special events like Anniversaries or the Worldwide Download Celebration. These banners include the new, main character, a new, side banner character, and many older Dokkan Festival exclusive characters. Legendary Summon banners are also new and premium, but strictly give LR class characters. These banners are normally considered less "hype", as the characters are historically not as good as Dokkan Festival characters. These banners do not include side banner characters and do not include any other exclusive characters, other than a large pool of older Legendary summon characters. There are also Carnival summon banners, which are a mix between Legendary Summons and Dokkan Festivals. These banners only have LR class characters, but have a featured unit list of other carnival characters and the characters are considered to be more "hype". There are also ticket banners, the tickets coming from various sources. These are usually free, and give lower-quality characters. The friend summon is a summon using Friend Points, obtainable by interacting with the friend system, and can give Elder Kai's, free-to-play LR's, and N and R class characters.

### Map Mechanics

3 randomly selected numbers (up to 6) are generated for the player to choose when moving across the map. Some fights force the player to stop, while some allow the player to pass over the tile. Once the player reaches the end of the level, there is a yellow star, which ends the level.

### Fight Mechanics

During the fights, the player's characters fight with an enemy via a puzzle system similar to match-3 games.

#### Ki Orbs

Multiple orbs of different colors are placed between the player's character and the enemy, and the player can match different kinds of orbs to do attacks. There are 5 types in the game, with each character and orb corresponding to one, and they are all represented as colors. These types include STR being red, PHYS being yellow, INT being purple, TEQ being green, and AGL being blue. Some types are effective to others, dealing more damage and taking less damage. Each orb collected gives one Ki, and gathering an orb of the same type also gives double the Ki. Gathering 12 Ki allows a character to perform a Super Attack, and gathering 18 Ki allows LR class characters to perform an Ultra Super Attack, maxing out at 24 Ki. After a certain amount of orb matches, the player unlocks "Dokkan Mode" for one of their characters, which requires them to swipe over 7 targets in a Z-shaped configuration quickly as a Ki orb passes over them. This allows that character to unleash a super attack that is much more powerful than the typical super attack.

#### Character Stats and Super Attack Effects

Each character has a base health, attack, and defense stat. These can be increased by leveling up the character, awakening the character, or activating their hidden potential. Characters also have Super Attack effects prebuilt into their Super Attacks, some including permanent attack and defense buffs, while others can stun the enemy.

#### Passive Skills

One of the main mechanics that characters use are Passive Skills. These are viewable from the card screen, and tell the player what the character's abilities are. Abilities include: additional super attacks, critical hits, dodge, damage reduction, guard, foreseeing enemy super attacks, and revival skills. In the modern-era of Dokkan, every new character has additional base attack, defense, and Ki already included in the Passive Skill. Some passive skills allow the character to gain additional attack and defense for every super attack they perform, or additional attack and defense for every attack they receive.

#### Boss Attacks

The enemy, also called bosses, are what the player fights in-game. There are 3 slots for every turn, with the boss attacking in each of them. The boss can super before and after the character's super attack on the slot one character, while only attacking after in slot two or three. Sometimes, the boss does their own super attack, dealing more damage.

### Team Building and Leader Skills

There can be six characters on a team, 7 when including the friend character. When building a team, a player must consider which categories or types the leader gives buffs to. For example, if the leader gives "Kamehameha" category Ki+3 and Attack and Defense + 170%, the player would search for characters who include that category. Players must also consider link skills. Each character has a set of links, which give additional buffs if 2 characters have the same links and are next to each other. So, the player must choose characters with similar link skills, to give cohesion to the team. Another thing players should consider is balancing types. It would be wise to have every type included on the team. The last thing that players should consider is having multiple character types. There should be at least one character with high defense and defensive mechanics. There should also be a few characters who can deal damage, and support the rest of the team.

### Types of Events

In Dokkan, there are multiple types of events, including Story, Growth, Awakening, Challenge, and Extreme-Z-Awaken. Story allows the player to relive certain moments in the Dragon Ball Z franchise, by fighting characters from the story. Growth events allow the player to level up their characters or obtain items to strengthen them. Awakening Events give awakening medals specifically for Dokkan Festival Exclusive characters. Challenge events are for experienced players, who want to fight a boss that can even give the new, premium characters a close match. Extreme-Z-Awaken events are to awaken older characters, who have aged out of the meta, to make them usable in challenge events again.

## Development and release

DualShockers had an interview with the game's producer Toshitaka Tachibana in July 2017, discussing the development and release of the game.

## Gacha scandal

On November 14, 2017, a new character Kefla (ケフラ) was advertised to be added into the gacha (loot box) pool, but only a few players were able to draw her successfully. The majority failed to spot Kefla's presence in the list of possible loot drops. This led to suspicion that the developer had intentionally manipulated Kefla’s drop rate, so most players would pour a lot of money into the game in an attempt to draw her in vain, while maintaining the illusion that she was still in the drop pool. Soon after the rumor went public, the developer halted the gacha function and denied user access to the list of gacha drops temporarily, explaining that the issue was an unintentional mistake. They then gave 300 Dragon Stones to all players on the Japanese servers. Another gacha scandal, was when STR Ultra Instinct sign Goku was released on the global version, but however, a bug in the code made those who pulled Ultra Instinct Goku, were instead given a Super Saiyan 3 Goku card.
