  • In STANDARD mode, the minimum level restriction for players without Dan courses cleared is set to 10-11-12 (equivalent to 7th Dan cleared).
  • In ARENA mode, an additional ARENA cube is awarded (does not apply to any mission bonuses).
• 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).

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 7th, 2023. e-amusement is required to play the event, and it appears with one player only.

At the end of each playthrough, the player chooses one of the maps to build their own metropolis. The number of area tiles that are given to the player is based on the following conditions:

• 1 area tile when playing STANDARD START.
• 2 area tiles when playing PREMIUM START (Japanese cabinets only).
• Using a DJ VIP PASS BLACK with any of the above two adds 2 tiles to the number of tiles awarded.
• 2.5 area tiles when playing PREMIUM FREE, regardless of time selected.
• 1.5 area tiles when playing ARENA MODE with STANDARD START.
• 3 area tiles when playing ARENA MODE with PREMIUM START (Japanese cabinets only).

These tiles can be used to build one of four buildings, which increase the base METRON awarded:

• Tourism Areas (観光エリア) which grant more METRON based on your DJ Level (3 METRON plus 1 for an A grade or better).
• Office Areas (オフィスエリア) which grant more METRON based on your Clear lamp (3 METRON plus 1 for a regular CLEAR lamp or better).
• Downtown Areas (繁華街エリア) which grant more METRON every play in general (30 METRON).
• Bank Areas (銀行エリア) which grant more METRON when you are not playing (1 METRON every four hours; up to 40 for one week).

Buildings can be constructed at any area blank tiles (indicated with a "planned construction" sign); upon construction, either the building can be upgraded (increasing the area level up to 10, except Banks) or demolished to build a new building (by pressing the VEFX button). Higher levels increases the multiplier bonus and METRON output.

The overall area level is displayed at the bottom left of the screen. Each map has 20 area tiles; building and upgrading enough areas increases the overall area level (capped at 50), which also influence the base bonus multiplier for the non-bank buildings itself (capped at 10). Reaching certain levels will also award EPO and V-Discs.

There are several different factors that contribute to the bonus, with a default base value of 1 (any multiplier changes will take effect on the next credit):

• Bank Areas increase by 2.5 per each building level, for up to 26.
• Tourism and Office Areas increase by 0.6 per each building level, for up to 61.
• Downtown Areas increase by 0.2 per each building level, for up to 21.
• Any Power Areas installed within a yellow area will provide a boost to adjacent areas.

Pressing the START button will exit the designer, which will present a list of songs available for unlock by spending on METRON the player has accrued (METRON do not carry over across other maps), and charts are unlocked in order of difficulty. Pressing the START button again closes the event screen.

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.
