• If your account is linked to beatmania IIDX ULTIMATE MOBILE, you can edit Song selection memo and be notified of any in-game events and casual tournaments via the app.
• First beatmania IIDX game since SIRIUS with several default system BGMs across game modes (outside STEP UP mode or event-based ones).
• EPOLIS' location test marks the first one for a beatmania IIDX arcade game since beatmania IIDX 25 CANNON BALLERS to not have a newly composed song by Takayuki Ishikawa on it.

MY POLIS DESIGNER

MY POLIS DESIGNER (マイポリスデザイナー) is the main unlock event of beatmania IIDX 31 EPOLIS. It started on December 7, 2023. This even will appear only if one player plays. e-amusement is required to play the event.

At the end of a round of play, you will earn METRON to unlock songs, as well as earn tiles that can be used to build up your own metropolis and earn more METRON. How many tiles you earn at the end of a round is based on the following:

• Standard Start will grant you 1 tile
• Premium Start (Japan only) will grant you 2 tiles
• Using a DJ VIP PASS BLACK with the above two will grant you 2 more tiles on top of the tiles given to you on that particular Start
• Premium Free will always grant you 2.5 tiles regardless of time chosen

These tiles can be used to build one of four buildings:

• Tourism Areas (観光エリア) which grant more METRON based on your DJ Level
• Office Areas (オフィスエリア) which grant more METRON based on your Clear Type
• Downtown Areas (繁華街エリア) which grant more METRON every play in general
• Bank Areas (銀行エリア) which grants more METRON when you're not playing, up to one week

Using a tile on an area that is already occupied will level up that area up to 10, raising the effects of that area and how much METRON you can earn from it. After you're finished with the designer, pressing the START button will bring up the music shop where you can use your METRON to unlock songs and their charts, and pressing it again will end the session.

Songs are listed in order, as shown in the music shop.

Other Unlock Events

WORLD TOURISM

The WORLD TOURISM unlock system, first introduced in beatmania IIDX 28 BISTROVER, returned on November 2nd, 2023.

Folders are added to the selection on any game modes for one player only. Playing a song from any folder will bring up a board with ten spaces between START and GOAL. Five spaces are awarded for playing a song (clear or fail does not matter), and an extra space is awarded for fulfilling each of the following conditions:

• DJ LEVEL AA or HARD CLEAR (or better)
• PREMIUM START (Japan only)
• LIGHTNING MODEL play

TOURISM BOOSTER, exclusive to Japanese LIGHTNING MODEL cabinets, also returns; it doubles the progress for each session if enabled.

Once the Q-Pro reaches the GOAL, a bonus is awarded, and the remaining spaces will carry over to the next board in the folder. If on the last board, the remaining spaces are lost. A number of how many spaces remain before the end goal are also shown.

The following rewards are awarded for each goal, in order:

1. 1500 EPO
2. 10 V-Discs
3. 3000 EPO
4. 20 V-Discs
5. Unlockable song

After playing a song from a WORLD TOURISM folder, the folders will disappear for the rest of the credit. Once the song has been unlocked from a folder, it will disappear from the selection entirely.

WEEKLY RANKING

Event page.

The WEEKLY RANKING feature was added to beatmania IIDX 31 EPOLIS on November 1st, 2023. The WEEKLY RANKING song changes every Wednesday at 12:00 noon.

You earn a star (the day after the period for a song ends) if your score in the leaderboards for the featured song's chart is high enough. Note that stars depend on each song's chart on both Single and Double Play, not on the whole song itself, which means you can earn up to six stars per song.

In the song list menu, a bar shows your WEEKLY RANKING star progress on the featured song's chart; the arrow determines your current position in the leaderboards:

• White star: if the arrow is located in the white section (within 75% in the leaderboards).
• Bronze star: if the arrow is located in the cyan section (within 50% in the leaderboards).
• Silver star: if the arrow is located in the gray section (within 25% in the leaderboards).
• Gold star: if the arrow is located in the yellow section (within 10% in the leaderboards).
• Platinum star: if the arrow is located in the very small blue section (within top 10 in the leaderboards).

New to this feature is Predicted Rating, which gives an estimate on any potential changes of ranking based on the current submitted score until the end of each period.

11/01/2023 to 11/08/2023 - アイドル / Covered by BEMANI Sound Team "HuΣeR × wac" feat. 佐伯伊織 11/08/2023 to 11/15/2023 - 傷つけど、愛してる。 / ツユ 11/15/2023 to 11/22/2023 - Submerge Serenade / lapix
