Gacha Probability Calculator
Enter your current pity (pulls since your last top-rarity unit) and how many pulls you have saved to see your chance of getting at least one top-rarity unit, including the 50/50 for the featured unit.
How this game pity works
this game advertises a base rate of 0.6% per pull for a top-rarity unit. On its own that base rate would make long droughts common — so the game layers a pity system on top.
- Soft pity kicks in around pull 74: the per-pull rate starts climbing steeply, which is why most top-rarity units appear in a tight window rather than at the base rate.
- Hard pity at pull 90 guarantees the top-rarity unit if you somehow reached it without one.
This calculator models that exact behaviour with a Monte-Carlo simulation, so the percentage you see reflects the real soft/hard-pity curve, not just the flat base rate.
The math behind the odds
Without any pity, the chance of at least one top-rarity unit in N pulls is:
P(at least one) = 1 − (1 − p)N
where p is the per-pull rate (0.6%). But this game raises p on every pull past 74, so your real probability accelerates dramatically once you enter soft pity — far faster than the flat formula suggests. Because of that ramp, we simulate tens of thousands of pull sessions and report how often you'd succeed, which is more honest than a single closed-form number — especially once the 50/50 is involved.
How to use this gacha calculator
- Enter your current pity. That's the number of pulls since your last top-rarity unit (0 if you just got one or are starting fresh).
- Enter pulls available. How many pulls you can currently afford on this banner.
- Set the guarantee toggle. Turn on “guaranteed featured” if you lost your last 50/50, so your next top-rarity unit is the featured one for certain.
- Read your odds. See your chance to land the featured top-rarity unit, plus the average pulls each top-rarity unit takes.
Worked example
Starting from 0 pity with 90 pulls saved, with 90 pulls from 0 pity you are guaranteed at least one top-rarity unit, because hard pity forces a drop on pull 90. Whether that guaranteed unit is the featured one then comes down to the 50/50 (unless your guarantee toggle is on). Lower your pulls or raise your starting pity and watch the headline percentage move in real time.
What is the 50/50?
On a limited banner, your first guaranteed top-rarity unit has roughly a 50% chance to be the featured one. Lose that coin-flip and you get a random standard unit instead — but your next guaranteed top-rarity unit is then the featured one for certain. So in the worst case it takes two pity cycles to secure a specific featured top-rarity unit. Toggle "guaranteed featured" in the calculator to model the case where you already lost your last 50/50.
Pull-planning tips
- Know your distance to pity. From your current pity, hard pity is 90 − (current pity) pulls away — budget for that worst case.
- Don't fall for the gambler's fallacy. Outside the pity ramp, each pull is independent — a long dry streak doesn't "owe" you a win.
- Carry your guarantee. If you lose a 50/50, your next featured unit is locked in — plan banners so you don't waste that guarantee.

Frequently asked questions
How accurate is this calculator?
It models the published base rate (0.6%), the soft-pity ramp that begins around pull 74 and the hard pity guarantee at pull 90. Exact internal numbers are not officially documented, so treat results as a very close estimate.
What is the 50/50?
On a limited banner, the first guaranteed top-rarity unit has roughly a 50% chance to be the featured one. If you lose it, your next guaranteed unit is the featured one for certain.
How many pulls until pity in this game?
Hard pity is at pull 90. From your current pity, subtract it from 90 to see how many pulls until a guaranteed top-rarity unit.
Does saving up improve my odds per pull?
No. Outside of soft/hard pity, each pull has the same 0.6% base chance. Saving pulls only increases your cumulative probability by giving you more attempts, and lets you reach the soft-pity ramp around pull 74 where rates climb.
