¶ ONGEKI
ONGEKI (the first version) worked the same as ONGEKI Plus to Bright MEMORY except with no NEW frame (only the BEST and RECENT frames.)

¶ Score Rating
if score < 800000
Above 800,000 points, score rating is the internal level (chart constant) plus a bonus based on the technical score. The bonus is linearly interpolated between:
| Score | Bonus | Slope |
|---|---|---|
| 1,007,500 | 2.0 | 0 |
| 1,000,000 | 1.5 | +0.01 for every 150 points |
| 990,000 | 1.0 | +0.01 for every 200 points |
| 970,000 | 0 | +0.01 for every 200 points |
| 900,000 | -4 | +0.01 for every 175 points |
| 800,000 | -6 | +0.01 for every 500 points |
Below 800,000 points, the rating takes the value at 800,000 points and begins to multiplicatively decrease starting from 1 and decreasing by 0.01 every 3,000 points. At 500,000 points or below the rating is 0.
¶ Overall Rating
Profile rating is the average of 3 frames, the Best frame, New frame, and Recent frame.
Best frames:
- OldBest30 is the sum of the highest 30 score ratings from previous game versions.
- NewBest15 is the sum of the highest 15 score ratings from the current game version.
- See New Versions for clarification.
- Bonus tracks are excluded.
- Duplicates are not allowed within frames / only one score is allowed per chart.
Recent frame:
- Recent10 is the sum of the highest 10 score ratings from a queue of 30 recent scores.
- Duplicates are allowed within the recent frame.
- Bonus tracks are excluded.
- LUNATIC/Re:MASTER charts are excluded.[1]
- The frame generally follows the last 30 plays, but there is some advanced logic for which scores it replaces in the queue:
- If the score’s rating would be in the top 10 of the queue:
- Remove the oldest score that has lower rating
- Add the newest score to the front of the queue
- Else, get the top 10 rated songs and look at their technical score. If this score’s technical score is higher than any of the technical scores of the top 10:
- Skip adding the song
- Else:
- Remove the oldest score
- Add the newest score to the front of the queue
- If the score’s rating would be in the top 10 of the queue:

¶ Score Rating
if score < 800000
Above 800,000 points, score rating is the sum of 5 factors.
- Internal Level - the chart constant
- Technical Score
- Grade Lamp (SS/SSS/SSS+)
- Clear Lamp (FC/AB/AB+)
- Bell Lemp (FB)
The lamps are bonuses given when you have ever achieved it on that chart -- example: if the current score wasn't a full combo, but you have achieved a FULL COMBO on the chart before, you will still get the +0.1 bonus from the lamp.
Below 800,000 points, the formula is the same as the one from Bright MEMORY: the rating takes the value at 800,000 points and begins to multiplicatively decrease starting from 1 and decreasing by 0.01 every 3,000 points. At 500,000 points or below the rating is 0.
Technical Score
Technical bonus is linearly interpolated between the following points.
| Score | Bonus | Slope |
|---|---|---|
| 1,010,000 | 2.00 | - |
| 1,007,500 | 1.75 | +0.01 every 100 points |
| 1,000,000 | 1.25 | +0.01 every 150 points |
| 990,000 | 0.75 | +0.01 every 200 points |
| 970,000 | 0 | +0.03 every 800 points |
| 900,000 | -4 | +0.01 every 175 points |
| 800,000 | -6 | +0.01 every 500 points |
Grade Lamp
A bonus is given based on your highest grade on the chart.
| Grade | Bonus |
|---|---|
| SSS+ | 0.3 |
| SSS | 0.2 |
| SS | 0.1 |
| S and below | 0 |
Clear Lamp
A bonus is given based on your highest clear lamp on the chart.
| Combo Lamp | Bonus |
|---|---|
| ALL BREAK+ | 0.35 |
| ALL BREAK | 0.3 |
| FULL COMBO | 0.1 |
| (none) | 0 |
Bell Lamp
A bonus is given whether you have a FULL BELL on the chart.
| Bell Lamp | Bonus |
|---|---|
| FULL BELL | 0.05 |
| (none) | 0 |
¶ Platinum Rating
A small bonus is given based on your platinum score on the chart. The game awards platinum stars if you reach a certain percentage of max platinum score.
| Stars | Ratio | Value |
|---|---|---|
| ☆☆☆☆☆ (rainbow) | 99% | 5 |
| ☆☆☆☆☆ | 98% | 5 |
| ☆☆☆☆ | 97% | 4 |
| ☆☆☆ | 96% | 3 |
| ☆☆ | 95% | 2 |
| ☆ | 94% | 1 |
| - | <94% | 0 |
¶ Total Rating
Refresh rating is the sum of 3 frames, the Best frame, New frame, and Platinum frame.
- OldBest50 is the sum of 50 highest score ratings from previous game versions.
- NewBest10DividedBy5 is the sum of 10 highest score ratings from the current game version (See New Versions), but each rating is divided by 5.
- PlatinumBest50 is the sum of the 50 highest platinum ratings from any version.
- Duplicates are not allowed within frames / only one score is allowed per chart.
(todo: what happens to LUNATIC 0 charts, Bonus Tracks?)
¶ Appendix
¶ New versions
Charts go into the NEW frame if they were released in the current version, and into the BEST/OLD frame if they were released in any previous version.
https://wikiwiki.jp/gameongeki/オンゲキ PLUS情報まとめ
- (version) and (version PLUS) are counted as different versions: RED Plus is a different version from RED.
- The only exception is Bright MEMORY, which is split into two versions: Act.1/Act.2, and Act.3.
Example - if the current version is Ongeki RED Plus:
- songs from RED Plus will go into the New frame
- songs from RED, Summer PLUS, Summer, Ongeki Plus, and Ongeki will go into the Best frame.
