Gachas

Gachas are a way for players to acquire more cards. New gachas are typically introduced with new events; the rate-up cards in these gachas will have both the character and attribute bonuses for these events.

=== Permanent ===
Gachas of the "permanent" type contain 4☆ permanent cards, which are all added to the general gacha pool. This means that these cards can be acquired from any gacha that uses this pool. The 4☆ rate in this type of gacha is 3%, however, a pity system guarantees certain 4☆ cards once the pull requirement is met. Permanent gachas can also be sparked, and doing so requires 300 permanent gacha seals or its equivalent.
=== Limited ===
Gachas of the "limited" type contain 4☆ limited cards, which are not added to the general gacha pool. This means that these cards cannot be acquired in any other gacha. The 4☆ rate of limited gachas is 3% and there is no pity system. However, there is still the spark system that requires 300 limited gacha seals or its equivalent.
Limited gachas used to contain 2 limited cards and 1 permanent card, however this was changed so they only contain limited cards. The last limited gacha to contain a permanent card was Overlapping Feelings―Words Snow Gacha. These permanent cards were sparkable with permanent gacha seals instead of limited gacha seals.
====Unit-limited====
Gachas of the "unit-limited" type are slightly different from the usual limited gachas. They're special gachas that run alongside World Link events and feature four limited 4☆ cards that each have a 3DMV Another Cut for a specific song.
=== Colorful Festival ===
Gachas of the "Colorful Festival" type have 4☆ rates of 6% instead of the usual 3%. This type of gacha has a spark system but not a pity system.
The types of cards this gacha contains varied over time. The first two Colorful Festivals, Entering 2021 - Colorful Festival Gacha and Leaving 2020 - Colorful Festival Gacha, contained only permanent cards. The 3rd and 4th Colorful Festivals, Half-Anniversary Commemoration Colorful Festival Gacha and Colorful Festival Gacha (June 2021), introduced a new type of card, Colorful Festival limited. These cards have unique skills, the accuracy scorer and life scorer skills. In addition, these cards are added to the Colorful Festival gacha pool, as opposed to the general gacha pool, so they can only be pulled in future Colorful Festivals. The Side Stories of these cards also feature Fragment Sekais that characters will travel to in order to resolve strong feelings they're having. Starting with the 1st Anniversary - Colorful Festival Gacha, Colorful Festivals now incorporate the event cards normally found on gachas that run alongside events.
==== Colorful Festival Dream Pick ====
The "Colorful Festival Dream Pick" type is a special case of the "Colorful Festival" type and allows players to choose 1 Colorful Festival limited and 3 permanent cards (out of a certain pool of cards) as a part of the rate up cards.
=== Birthday/Anniversary ===
Gachas of the "birthday" (or anniversary for ) type introduce a new type of card type - birthday/anniversary cards. This type of card is only available from the gacha it debuted in, or a rerun of said gacha.
The card drop rate of a birthday/anniversary card is 3% and replaces the 4☆ card rate for birthday/anniversary gachas. This gacha type has no pity and is limited to 100 pulls (the birthday/anniversary card for that gacha is guaranteed to drop within that 100 pulls limit).
This gacha is sparkable using a unique seal type, Birthday gacha seals.
The only cards available in this gacha are cards associated with a certain character. For example, in HAPPY BIRTHDAY Gacha - Kiritani Haruka, only Haruka's 2☆, 3☆, and birthday card are in the gacha pool.
4☆ cards of that character are not included in the pool and are replaced with the birthday/anniversary rarity type card.
=== Premium Present ===
Gachas of the "Premium Present" type contain only permanent cards. The 4☆ rate is 3%, but there is no pity or spark system. In addition, this gacha can only be pulled once. Players who do pull in this gacha will receive all of the Premium Present costumes available for that gacha.
=== Select List ===
Gachas of the "Select List" type allows players to pick 10 permanent 4☆ cards (within a certain pool). Once a player pulls on a Select List gacha, they will be guaranteed 1 of the 10 cards they picked. These gachas may only be pulled once, and require 3000 paid crystals.
=== Memorial Select ===
Gachas of the "Memorial Select" type allows players to pull once with 3000 paid crystals. The 4☆ rate is 3% and has no sparking or pity system, but after pulling on this gacha, players will recieve a 4☆ Select Voucher. Vouchers recieved from the gacha can be exchanged in the Character Exchange menu where players can select to recieve a permanent 4☆ card. Certain 4☆ cards are not elligible for exchange.
=== Guaranteed 3☆ ===
The "Guaranteed 3☆" type gacha appears in the gacha tabs when the player has a 3☆ or higher guaranteed ticket in their inventory. As the name suggests, it guarantees the player receives a 3☆ card or higher (a 4☆ card).
This gacha has no spark or pity system and no gacha seals.
=== Guaranteed 4☆ ===
Gachas of the "Guaranteed 4☆" type allow players to pull once with 3000 paid crystals and receive at least one random permanent 4☆ card.
This gacha has no spark or pity system and no gacha seals.
=== Free 10-Pull ===
Gachas of the "Free 10-Pull" type are gachas that appear during special occasions and can only be pulled on using Free 10-Pull Gacha Tickets to do 10 pulls and guarantees at least a 3☆ card.
This gacha has no spark or pity system and no gacha seals.
=== Happiness Package ===
Gachas of the "Happiness Package" type guarantee a 4☆ permanent card (within a certain gacha pool), but may only be pulled once and require 3000 paid crystals. In addition to a guaranteed 4☆ card, players can choose one of the following items:
* 1 pure crystal of feelings
* 150 song cards
* 600 miracle gems
* 900 magic cloth + 90 magic thread
* 150 mysterious seeds
* 60 skill up scores (intermediate)
* 3,000,000 coins
The 3900's Eve - Happiness Package Gacha had the additional option of:
* 50 3900's live bonus drinks
=== Attribute/Event Bonus ===
Gachas of the "Attribute/Event Bonus" type contain permanent cards (containing current event rate up cards) with a rate-up towards cards of atleast 25% event bonus to the current event active.
These gachas share the same gacha seals as the current event gacha and can be used intertwiningly. There is no pity in these gachas.
NOTE: These gachas are no longer available and were discontinued as of the Cherry Blossom Across Sekai, Interconnecting Our Feelings event.
=== World Link Support ===
Gachas of the "World Link Support" type are available just before the start of a World Link event and end around the same time as their corresponding event. These gachas contain permanent cards for only one unit and VIRTUAL SINGER cards with that subunit - the unit depending on what the upcoming World Link is.
==Rerun==
Rerun gachas are, as the name suggests, reruns of previous limited gachas. Reruns typically occur around a year after the limited gacha was released (or a year after the last rerun) so players can try again for limited cards they didn't get.
The types of gachas that receive reruns are:
* Limited gachas
* Birthday/Anniversary gachas
Rerun gachas do not carry over any pity system or gacha seals from their initial gachas.
For example, the Fluffy☆Dreamland Gacha - Reprint would not carry over any seals or gacha pity from the Fluffy☆Dreamland Gacha.
== Mechanics ==
=== Flip ===
When pulling on a gacha, a animation will be played which signifies whether or not a pull contains a 2☆, 3☆ or 4☆. Flips only occur during 3☆ pulls.

File:3☆ pull animation phone size.jpg|A 1/10-pull that contains a 3☆
On rarer ocasions during 3☆ pulls, a flip animation will be triggered when Miku lands the floor during the animation. The floor should be blue instead of yellow when a flip occurs. When a flip animation is triggered, it signifies that the pull will contain atleast one 4☆. Flips can occur in both 1-pulls and 10-pulls and on any gacha.

Before it was changed, the flip animation would instead be signified by the colour of the triangles (blue/pink as 4☆, yellow as 3☆).
===Pity===
In permanent gachas (gachas that use the green seal to spark), there is a pity system that guarantees a 4☆ card once a certain number of points is reached. At 50 points, any 4☆ card available on that gacha is guaranteed. At 100 points, one of the rate-up cards for that gacha will be guaranteed. To get points, pull on the banner. For every pull only using paid crystals, players will get 1 point toward their pity meter. For all other pulls, players will only get 0.5 points toward their pity meter. This means that if there a pull that uses both free and paid crystals, that pull will only contribute 0.5 points towards the pity meter. For 10-pulls, treat each of the pulls in the 10-pull as a singular pull to calculate points.
=== Spark ===
Rate-up cards can be sparked on their gachas by using 300 seals. Seals are earned by pulling on the gacha; each pull gives the player one seal. Players may optionally use up to 10 seal exchange tickets to lower the number of seals needed to spark, with each seal exchange ticket counting as as 10 seals.
If a player has 1 seal exchange ticket, they will only need 290 seals to spark. With 2 seal exchange tickets, only 280 seals are needed to spark, and so on. If a player has 10 seal exchange tickets, they will only need 200 seals, in other words, 200 pulls, in a gacha to spark a card. 
Apart from a few exceptions, seals are not shared between gachas; pulling on one gacha does not provide seals for another. The exception is when there is a Colorful Festival gacha that runs before a limited gacha for an event. That Colorful Festival gacha will also contain event cards in the rate up pool. In addition, the duration of the limited gacha following the Colorful Festival one will be ran for a shorter period of time compared to normal.
Note that permanent gachas, limited gachas, and birthday gachas all have different seals. Similarly, the seal exchange tickets also have permanent and limited versions. Permanent cards on permanent gachas only accept permanent seal exchange tickets, while permanent cards on limited gachas can accept permanent or limited seal exchange tickets. However, limited cards only accept limited seal exchange tickets and birthday cards have no tickets available at all.
