Information here applies to beatmania IIDX 30 RESIDENT, as many significant changes have been made from CastHour. For CastHour information, please refer to the archived page.

This page is an active work in progress; information will be updated as available. It has been assumed that American region cabs will follow Asia region, but this is not yet fully confirmed.


This is the most commonly played game mode on AC.

You can play three songs, plus a potential 4th song in Extra Stage, plus a potential 5th song in One More Extra Stage.

standard mode

You are not guaranteed three songs, however. If you fail to clear the song, you do not advance to the next stage. Exception is given to the first stage - if you fail a song that is level 5 or under, you can still advance to the second stage.

Same song cannot be chosen more than once.

Level Limitations

There are limitations to what difficulty charts you can pick in Standard play. The table below shows the highest difficulty chart you can pick under certain conditions.

DAN Class Play Count 1st STAGE 2nd STAGE FINAL STAGE
None - 5th Dan - LEVEL 8 LEVEL 10 No restrictions
6th Dan LEVEL 9
7th Dan LEVEL 10
8th Dan and above Under 100 LEVEL 10 LEVEL 11
100 or more LEVEL 11
10th Dan and above 1000 or more No restrictions
Kiwami Kaiden 800 or more

Extra Stage

To enter Extra Stage, certain conditions must be met in the final stage. These are the requirements that hold true since Happy Sky.

Level SP Requirement DP Requirement
1 ALL GREAT clear ALL GREAT clear
4 FULL COMBO clear
5 FULL COMBO clear
6 Clear with 100% gauge
7 Clear with 100% gauge Clear (Assist Easy gauge or above)
8 Clear (Assist Easy gauge or above)

There are important regional differences to note:

  • In Japan region, PASELI must be used as the form of payment when entering Standard (Premium) mode in order to enter extra stage. (In other words, coin play cannot enter extra stage)
    • This includes old IIDX cabs at American Round 1, which are on the Japanese eamuse network and PASELI cannot be used.
  • In Asia region and America region (including Lightning Model cabs at American Round 1), Extra Stage can be entered even on coin play Standard mode, as PASELI is unavailable.

Additional notes:

  • Any option can be used - assist options like EXPAND JUDGE or H-RANDOM.
  • If two people are playing at the same time, only one player needs to meet the requirement.

Event Extra Stage / One More Extra stage

Special Extra stage and One More Extra stage can also be accessed during events. The requirements depend on the active event.

Free Modes

Free mode is visually similar to Standard mode, but is less restrictive when it comes to what songs you can play, at higher cost to you (or fewer songs).

Notable differences from Standard:

  • Same song can be chosen multiple times.
  • No restrictions on the difficulty level.
  • Extra Stage events cannot be accessed.

There are many variations:


Selectable from Mode Select. Two songs are guaranteed.

Free Plus

free plus mode

Selectable from Mode Select if two players are active. Three songs are guaranteed.



In Mode Select, while Free Mode is in focus, if you press all three black keys, you can switch to Hazard mode. You are guaranteed four songs, but you play on Hazard gauge which immediately fails you out if you lose a combo. EXPAND JUDGE is disabled.

Premium Free


You are given a time limit, but you can play any number of songs without restrictions. This tends to be the most expensive option, but the most flexible way to play.


In Japan: this is a PASELI only mode, ranging from 6-30 minutes.

In regions outside of Japan: can be accessed by coin play, price configurable by operator, usually 1.5 - 2 times the price of a standard play. Fixed to 10 minutes. It can be disabled by the operator. This also the only way to play a session with V-Discs - see V-Discs section below.

Time starts counting down the moment song select screen is shown; time continues to count down during loading screens. If the timer runs out during a song, your session will end after the song ends. If the timer runs out on the song select screen, you will be able to start one last song (you are given about 15 seconds of grace period to do so).

While in song select, press VEFX + EFFECT ON keys to exit out early. While playing a song, press VEFX + EFFECT ON keys to exit out from the song. On the result screen, hold VEFX + EFFECT ON keys and press a white key to play the same chart immediately without going to the song select screen (Normal Retry feature).

If you are subscribed to eamusement Premium course and activated Platinum Members Card on the profile, you can perform Quick Retry; by holding VEFX + EFFECT ON keys during the song, you can restart the song without going through the result screen.


Three songs are guaranteed, but sometimes you can play four. This is a “training” mode that also has a story and hidden unlockables.

step up

Tasks folder

20 random charts are provided in this folder that matches your current step-up skill level. Step-up skill level determines what level of songs show up in this folder. The skill level isn’t shown to you, it is a decimal number that is stored on your profile. This number determines what level of charts are given to you in this folder.

The step-up level is carried over from the previous version, but with an upper limit (level 9s). If you play class mode before entering Step Up mode for the first time, you will get an appropriate initial placement. If you play Step Up without doing that, you will start on level 1s.

Depending on your result, your step-up level will change. The most impactful factor is your DJ level. Getting a higher rating (AAA) will result in a greater increase.

The gauge type acts as a modifier. ASSIST-EASY or EASY gauge clear will result in a smaller increase, but failing will result in a large decrease (compared to normal gauge).

HARD and EX-HARD gauge clears will result in a slightly larger increase, but fails will have less impact than a normal gauge; however, this is negated if you fail out early in a song and end up with a very low DJ LEVEL (E or F). FULL COMBO clear will greatly increase the level.

There is no penalty of any kind for using EXPAND-JUDGE.

Normally, new songs from the current versions do not show up in this folder. Once you complete the entire step-up story and see the ending, then you will start to see new songs show up.

Alternate Tasks folder (Ura)

A new folder will appear once you beat the entire “story” for step-up mode. This is similar to the regular Tasks folder, except that new songs from the current version will also show up.

Review folder(s)

There are up to twelve folders for each level. You can only open folders that are 1 level below the current step-up level. It contains songs that you have already played in other modes, with the following restrictions:

  • New songs from the current version will not show up.
  • You must have EX-SCORE greater than 0 on it already.
  • You must have the song unlocked, if it’s part of an unlock event.
  • Songs played in class mode does not count as they save as “NO PLAY”, even if you have greater than 0 EX-SCORE.

Regional differences to note:

  • On Japanese network using coin play, or on old J-region cabs at American Round 1, you are limited to [current level - 2] folders. In other words, review level 11 and 12 folders will not be available.
  • On PASELI play, or in Asia / America region cabs, this restriction does not exist.

Practice match folder

Once you fail a class in class mode, a new folder will show up to practice four songs from that course. Class mode gauge (expert gauge) is used instead; it starts at 100% in the beginning of each song, but it can be changed by holding the VEFX + EFFECT button and pressing number on the number pad.

This doesn’t show up until Chapter 2 of the story (to be confirmed for Resident)

Level adjustment (new in RESIDENT)

step up level

In RESIDENT, you can adjust the amount in which your step-up level increases or decreases. Hold VEFX+Effect, and press keypad #5; cycle through 小 (small) 中 (medium) 大 (large).

(This option is currently bugged and may not correctly show for everyone - it’s suspected that it only shows up when you card in from 1p side).

Class Mode

dan mode

Class mode (dan-i-nintei) measures your skill level by playing through a pre-defined course of four songs, and awards you with a badge of honor.

Check out the page on class mode for courses in recent versions; also Remywiki has a very good explanation of the mode and the songs in each version.



Online battle mode, or local matching (within the same store) are available. Four stages are guaranteed.

You enter a lobby with up to four players - if there are fewer than four, you are matched up with bots. Each player picks a song, and the lobby plays through four songs.

If you are not matched at least one person (if you’re matched with 3 CPUs), you are given the option to enter FREE MODE instead.

Leggendaria charts cannot be chosen outside of Japan, as it requires PASELI start.

Based on your arena tier, song selection is limited to the following levels (- column is for regular beginner/normal/hyper/another charts, LEG is for leggendaria charts)

A Level B Level C Level D Level
A1 12 12 B1 12 11 C1 10 10 D1 9 9
A2 B2 C2 D2
A3 B3 11 C3 D3 8 ×
A4 B4 C4 D4
A5 B5 C5 D5 7

Daily bonuses

Daily bonuses have been removed except one: on Saturdays (Japan time), restrictions are lifted for review level folders.


In this section, we will focus on Asia and American region cabinets for simplicity. For Japanese cabs, refer to the official site. Remember that at American Round 1 locations, Lightning Model cabs are American region, while the legacy cabs are Japan region, but PASELI cannot be used.

Earning V-Discs

For Japan region cabs, V-Disc is premium feature only available when playing with PASELI.

In other regions, only Premium Free mode provides V-Discs. You are given:

  • 3 V-Discs if coin play
  • 7 V-Discs if paying with PASELI
  • Additional +3 V-Discs if Platinum Members card is active on the profile

Spending V-Discs

In Premium Free, 1 V-Disc is spent for each LEGGENDARIA chart played.

Conversion of unused V-Discs

At the end of each credit:

  • Remaining unused V-Discs are saved to your profile. Once you collect 100 unused V-Discs, the game will forcibly exchange 100 V-Discs for one DJ VIP PASS BLACK.
  • It should however be noted that unused V-Discs do not carry over to the next credit, you are only able to spend the discs given to you at the start of each credit (i.e., you can’t spend previously unused V-Discs).


black pass

If you have one from collecting 100 unused V-Discs – you can choose it before going into Standard mode. DJ VIP PASS BLACK gives you all V-Disc benefits for free – guarantees three stages, removes level restrictions in all stages, advances you to Extra Stage if you clear final stage without needing to meet the requirements, allows Leggendaria charts, and allows you to pick the same song more than once.
