Feature Request: "Reverse Score Mode" for osu!mania (Start from 1,000,000 and deduct for each non-perfect hit)

[spongenotcake]

Hi there,

I'd like to suggest a simple yet useful feature for osu!mania: a reverse scoring mode that starts from 1,000,000 and deducts points with every non-300g (or highest judgment) hit.

🔍 What is it?
Instead of building score from 0 up, this mode would begin with a perfect 1,000,000 and subtract points based on judgment accuracy:

300g: no deduction

300: small deduction

200: larger deduction

100, 50, miss: increasing penalty

(This follows the same logic as the accuracy system — just visualized as a countdown instead of accumulation.)

✅ Why is this useful?
Real-time progress awareness: Players can immediately see if they’ve already dropped below a goal score (e.g., 990k or 970k for SS/S).

Time-saving for score chasers: No need to play through a full map just to discover they missed the cutoff halfway through.

More intuitive for players familiar with rhythm games that emphasize precision over combo-based scoring.

Does not impact actual score calculation or rankings, only changes the way score is visually presented.

💡 Optional additions:
Make it a toggleable UI option, e.g., “Reverse Score Display” in the settings.

Could work with existing accuracy formula; only the score counter display changes.

🛠 Technical feasibility:
osu!mania already calculates judgment accuracy and score contribution per hit. This feature is primarily a frontend/UI change and should be lightweight to implement, especially in osu!lazer.

Let me know if this is something worth pursuing. I'm sure many mania players, especially those focused on accuracy, would appreciate this option.

Thanks for reading!

I have never seen any game that does this. And the accuracy counter has such a mode option already (minimum and maximum achievable) because there are games that do it. Are the accuracy counter modes enough?

Note that if this were ever implemented, it can be applied to every other ruleset.

You're right — most rhythm games don’t have this kind of system by default.
However, there are games that implement a similar idea, such as maimai (arcade) and takumi³ (mobile). That’s why I hope a similar design can be introduced into osu!mania. Not only would it improve usability, but it would also give accuracy-focused players a more intuitive way to determine whether they're on track to meet their score goals.

From what I understand, the default accuracy counter in osu! calculates accuracy based on notes that have already been hit, not the full map.
In many cases, if I aim for, say, 99% accuracy, and I make a heavy mistake in one section, the accuracy counter may drop to 95–96%, and slowly rise back up — but I can't clearly tell whether that one mistake made it impossible to reach 99% overall.

For example, in a 1000-note chart, if I miss the 2nd note but hit the 1st perfectly, I'd want to see 99.90% — not 50.00%.
This lets me immediately know that I’m below my goal, even without finishing the map.
I believe this logic could apply to all rulesets.

I'm not entirely sure how osu!mania’s scoring system works under the hood, but if it's purely based on accuracy, then this reverse scoring mode should be feasible.
Using the same example, I’d expect the score to drop from 1,000,000 to 999,000.
Of course, this relies on the fact that mania has a fixed maximum score. Other rulesets may have more complex or combo-based systems, and I’m not sure if they can support a reverse score mode as easily — since they’d need a consistent way to calculate the theoretical maximum score first.

That’s my explanation!
If there’s anything unclear, I’d be happy to elaborate further.
Hope this helps — and thank you again!

Would be nice if the reply is not ChatGPT...

I'll just ignore this, because it outright ignored the mode option toggle for the accuracy counter.

[spongenotcake]

You're right — sorry if it felt like I ignored your point earlier. I haven't seen that the accuracy counter has a minimum/maximum prediction mode.Could you tell me where is it?
And also,I hope the score system would have same function.

And yeah, I used ChatGPT to help structure my thoughts since I wasn’t confident in my English — but the idea and intention were entirely mine,I just used it for translation,hope you will understand.

Thanks for your time anyway!

Ctrl-Shift-S during gameplay to open skin editor and click the accuracy counter:

Score is 15% combo and 85% accuracy. Ref:

osu/osu.Game.Rulesets.Mania/Scoring/ManiaScoreProcessor.cs

Lines 28 to 33 in ac9ede8

	protected override double ComputeTotalScore(double comboProgress, double accuracyProgress, double bonusPortion)
	{
	return 150000 * comboProgress
	+ 850000 * Math.Pow(Accuracy.Value, 2 + 2 * Accuracy.Value) * accuracyProgress
	+ bonusPortion;
	}

And also,I hope the score system would have same function.

If this gets enough upvotes maybe, but score is fundamentally a number that goes up throughout gameplay.

Very good idea, this concept is great from an accuracy standpoint !

The Accuracy display is one thing, but it doesn't perfectly translate to the score value, which is what we're actually trying to achieve.

I have a potentially workable idea:

The combo score starts at full points. When a combo break occurs, the combo score is calculated based on the current maximum combo and the theoretical maximum combo (though this portion of the score may increase as gameplay progresses).

For the accuracy score, it can be calculated by assuming all future judgments are perfect (300g). Based on this theoretical scenario, the theoretical maximum accuracy is derived (it will decrease when a Great or worse judgment is hit), yielding the theoretical accuracy score.

Adding the two together gives a reference score, and this scoring method should yield the same score during settlement as when using positive scoring
