A reboot of the series,[6] Chunithm NEW, based on the original Chunithm, was released in Japan in November 2021 and worldwide in March 2022.[7] Along with Chunithm NEW, new cabinets are also released along with the new game. Many new features and improvements were made to the new machine, such as:

  • 120fps monitor
  • Upgraded speaker, earphone jack, and touch panels
  • Digital payment support
  • Avatar and arena battle
  • Level adjustments, extending from level 14 to level 15

These new cabinets are called "Gold Model" while old cabinets are now called "Silver Model". Old "Silver Model" cabinets can be converted using conversion kits to run Chunithm NEW.[8]

Gameplay

edit

In Chunithm, players use touch and motion-based sensor bars to input commands that correspond to the notes scrolling down from the top of the screen. Depending on the type of note, players may be required to tap, hold, or slide their fingers against the bottom sensor bar or wave their hands up and down in the air between the sensors located on either side of the machine. The types of notes present in Chunithm are the following:

  • TAP: The most common type of note, simply tap it when it reaches the judgement line. It is colored red.
  • ExTAP: A gold colored variation of the TAP note, which will almost always grant the maximum judgement of "JUSTICE CRITICAL" when tapped, so long as you are not extremely early or late.
  • HOLD: Visually, HOLD notes appear to be two TAP notes connected by a gold gradient, the player must tap and keep holding when the first note reaches the judgement line, and release as the tail end reaches the judgement line. The timing of the release is not important, but it is possible to let go too early, which would result in a MISS.
  • SLIDE: SLIDE notes function almost identically to HOLD notes, with the exception that SLIDE notes can move left or right across the playfield. The player must move their hands in accordance with the direction it is moving; visually, they appear very similar to HOLD notes but colored blue.
  • AIR: AIR is a modifier that can be added on top of the above-mentioned note types, visually presenting as a green arrow pointing up or a purple arrow pointing down. In the case of a green up arrow, the player must hit the regular note, and then lift their hand through the AIR sensing zone. Purple AIR arrows are typically found after an AIR-HOLD or AIR-ACTION section, as they require the player to quickly drop their hand down through the AIR sensing zone and onto the touch sensor.
  • AIR-HOLD: A long green note that can be added onto an AIR note, requiring the player to keep their hand in the AIR sensing zone until the note ends.
  • AIR-ACTION: Functioning as an AIR version of the TAP note, the player must wave their hand up or down in the AIR sensing zone with correct timing, mimicking a tap in the air.
  • FLICK: Exclusive to the two highest difficulties, "MASTER" and "WORLD'S END", FLICKs function similarly to TAP notes, however instead of simply tapping, the player must quickly swipe their hand to the left or right as the note reaches the judgement line.
  • DAMAGE: Exclusive to "WORLD'S END", DAMAGE notes function as the polar opposite to TAP notes. Tapping a DAMAGE note at any point will result in a MISS, and the player must simply not touch them in order to get a "JUSTICE CRITICAL".

CHUNITHM NEW introduces two new AIR note types:

  • AIR-SLIDE: Due to the methodology with which the game detects AIR inputs, AIR-SLIDE notes are functionally identical to AIR-HOLDs; they can move left or right like SLIDE notes, however, this is simply for visual flair.
  • AIR-CRUSH: Similarly, AIR-CRUSH notes are merely just a visually distinct version of AIR-ACTION, there can be many of them stacked on top of each other, while only requiring a single motion to be hit.

Scoring

edit

Chunithm features several scoring mechanics based on your performance of a song.

During gameplay, there is a gold meter at the top of the screen, this is your GAUGE. Below it is an indicator that tells you how many times you must fill it in order to CLEAR the song. You fill the GAUGE by hitting notes consecutively, missing a note will cause it to rapidly deplete.

After completing a song you are taken to a score screen where you are shown a variety of details, such as your grade, total judgement counts, and score, as well as a handful of other details if the player is playing on a registered online profile.

Your score, and thus your grade, is determined by calculating your overall accuracy using the below values, and then multiplying by 10000.

Judgement Accuracy rating
JUSTICE-CRIT 101%
JUSTICE 100%
ATTACK 50%
MISS 0%

For example, if you were to play a song with 300 total notes and get 280 JUSTICE CRITICALS, 18 JUSTICES, 1 ATTACK, and 1 MISS, the formula for your accuracy rating would be  

The table below lists all of the achievable grades as of LUMINOUS PLUS

Grade Score requirement
SSS+ 1,009,000 ~ 1,010,000
SSS 1,007,500 ~ 1,008,999
SS+ 1,005,000 ~ 1,007,499
SS 1,000,000 ~ 1,004,999
S+ 990,000 ~ 999,999
S 975,000 ~ 989,999
AAA 950,000-974,999
AA 925,000-949,999
A 900,000-924,999
BBB 800,000-899,999
BB 700,000-799,999
B 600,000-699,999
C 500,000-599,999
D 0-499,999

Your score is also assigned a title, depending on a few different goals. The available titles are as follows:

Title Condition
ALL JUSTICE! Clear a song without getting any judgements below a JUSTICE.
FULL COMBO Clear a song without getting a MISS.
CLEAR Fill up your gauge enough times by the end of the song. (varies per song)
FAILED Fail to fill up your life gauge the required amount.
FULL CHAIN Multiplayer Exclusive: All players achieve a FULL COMBO or better.


Rating

edit

In Chunithm, the rating system exists as a rough indicator of a player's skill level. Rating is calculated from the player's top 30 scores as well as their top 10 scores from the most recent 30 songs that they have played.

With the launch of CHUNITHM NEW, the rating system underwent a redesign, dividing it into nine levels based on color.

Rating Color
0.00~3.99 GREEN
4.00~6.99 ORANGE
7.00~9.99 RED
10.00~11.99 PURPLE
12.00~13.24 BRONZE
13.25~14.49 SILVER
14.50~15.24 GOLD
15.25~15.99 PLATINUM
16.00~17.37 RAINBOW
