D4DJ Groovy Mix

 is a rhythm game developed by DONUTS and published by Bushiroad, based on the Dig Delight Direct Drive! (D4DJ) franchise. It was released in Japanese on October 25th, 2020 and became available in English as a separate application on May 27th, 2021 for iOS and Android devices.

Story
"Now it's your turn!" Those words have connected generations across time. "D4 FES", a DJ festival that is the stuff of legends. Inspired by this festival, Japan experiences a new dawn in DJ culture. As DJs become the main method for people to experience music, performers called "DJ Units" have begun to appear. A culture that can be enjoyed by anyone, young or old, DJing has become an indispensable music genre. And now, 6 new DJ Units set their sights on this floor. The story of these girls aiming for the greatest moment begins!

Gameplay
D4DJ Groovy Mix is a free to play rhythm game which features a Story mode and Live mode as well as members of six units: Happy Around!, Peaky P-key, Photon Maiden, Merm4id, RONDO, and Lyrical Lily.

There are also secondary characters affiliated with D4 Fes., including members from backup units Lynx Eyes and Scarlet Canary.

All the units and characters have several voiced conversations engined with Live2D in Unit's own stories or on the D4DJ world map including special in-game events (e.g. halloween, character's birthday celebration).

Lives
There are four types of Live modes for players to choose from: Free Live, Multi Live, Medley Live, and Floor Challenge. There are a total of five note types:
 * Tap notes, blue in color, are activated by simply tapping the icon
 * Hold notes, yellow in color, are activated by tapping and holding down the icon
 * Slider notes, activated by moving the slider at the bottom of the screen in the direction of the corresponding pink icon
 * Backspin disc notes, orange in color, are activated by flicking a note in any direction. This triggers the Backspin mechanic, in which notes in the center reverse their movement for an instant before resuming normal movement.
 * Top Stop disc notes, red in color, are activated by tapping and holding down the icon. This triggers the Time Stop mechanic, in which notes in the center stop until the end of the hold note.

The players are tasked to tap the notes correctly according to the rhythm and type of note in order to receive a score. When you miss or near-miss one of them, your health points, shown at the top-right of the screen will decrease, the game will fail if your health points will drop to 0, in this case you will not receive any rewards. Depending on the player's results, they will be able to receive rewards like practice tickets or gems to use for training and reading cards.

For Score Mechanic system, check Score Mechanics.

Free Live
In Free Live, players are free to choose to play songs from the current discography without the limit of an in-game regenerating energy system, although the game does have in-game regenerating boosts.

Multi Live
In Multi Live, players are put in teams with other randomly chosen players in real time where they play a Live together for the highest possible score. Instead of only getting your score, the total of all scores are put together. To join a Multi Live, you can either create your own or enter someone else's room.

There are few variations of Multi Live that work a little different from the normal one:
 * Multi Medley Live: Only available during Medley event. Four players will choose the song they want to be mixed in the medley, and the game will immediately mix it out for this play.
 * Battle Live: Only available during Bingo event. You can consider this as a four-player MATCH, as you no longer use the skills from other players' cards.

Medley Live
In Medley Live, players can create their own setlists by connecting four different songs. Players may also share their setlists via randomly-generated IDs.

If the setlist is created in a certain order, the setlist itself will act as a secret command, and the player will gain access to corresponding hidden song. You will hear Airi saying, "Well done! (よくできたわね！)", if done correctly.

Floor Challenge
In Floor Challenge, players are required to reach the designated score marker to clear the stage, while being limited to use only the cards that matches the Floor conditions (e.g. Only Happy Around! cards can be used in Happy Around! Unit Floor). Up to 16 cards can be used to form a Floor deck exclusively for this mode.

Attributes
Each card or some of limited club items owned one of five available attributions :


 * (Cards • Club Items)
 * (Cards • Club Items)

The attributes don't make a difference in the score you get while playing the game, but they are used for Event bonuses if you use a certain type and specific shards of the attribute are required to Train your members.

Events
Main Article: Events

Medley
For every live show played (either free-live, multi-live or medley), song points are earned. These song points can be spent to play one of the three sets of medleys for a chance to earn a great deal of Event points.

Each medley has their own score-ranking with the highest scoring players receiving Titles and other Ranking Prizes.


 * Note that setting your main unit with the featured bonus members and attribute can help you get a high score and maximum points.

Poker
After completing a live show, a card is drawn out of your poker hand, starting with 2 cards. The pattern of the suits of determine the rank of your hand after all 5 cards are drawn. The higher the hand rank, the more coins you get. Starting from the Indigo Bullet event, you can earn titles based on a pairing of characters drawn from your hand.

Link Bonus
Getting specific character suit combinations will reward bonus coins.

The following table lists all possible combinations along with bonus coin amount:

Bingo
For every 50 event points, you will receive a bingo ball with a number on it. The number can range from 1-75 (standard bingo). If your current bingo card has a number hit (matching number), you will receive a small reward from a pool of items. Continue to collect numbers to receive BINGO. Once you receive a bingo, you can trade in your card for another one, or hold onto the card to continue earning more rewards. Completing the entire card also gives you a completion reward.

Starting from D4 FES. -Shuffle Vivid-, every time you move on to the card with the card number ends in 0, the event points required for one bingo ball increases, and the reward from the cards will become better. This is until you move on to your 40th cards. Details for points required is listed below:

Slot
Introduced in the To my future self event. After playing a live, you will receive SLOT medals that can be used in the D4DJ Groovy SLOT. You can use 300 slot medals to play the slot once and 3000 slot medals to get 10x the rewards. Winning in the slot gives you items, and getting a Jackpot gives you Slot Exchange Points of that character (since Prayers Will Surely Be Answered) which can be used in the Exchange for club items and character-specific items. If the player is lucky enough, after hitting the jackpot the GROOVY BONUS is activated, which serves as a Jackpot Fever for the player for the next 50 spins.

Raid
Introduced in Adventure Awaits Us (Part 1). In this event, the players will have to work together to deplete (or fill up, depending on the Raid theme) the target gauge. The event points received will become "damage" dealt to the target. Once the gauge is completed, the damage ranking will be calculated and determined, and the players will receive prizes depending on the player standings. The player will also receive special rewards if the "damage" they dealt makes the target gauge hit the designated marker (e.g. 80%), or if the player manage to deal the final blow.

Raid events are usually combined with game campaign run by officials, with the contents usually be that extra rewards will be given to all players after the event is over if they manage to reach the goal the officials set.
