Input Your Pull History
Statistic Guide
The Math of Salt:
Calculates the probability of observing k consecutive failures at rate p.
Most modern gacha games increase rates exponentially after a specific pull count (e.g. 74 in Genshin).
If you are in the 1% percentile, it means 99 out of 100 players were luckier than you.
Input your pull count to measure your current luck percentile.
Mastering Gacha Luck Analytics: Percentiles & Probability
Every gacha player has experienced the "mathematically cursed" pull session where a 5-star unit seems statistically impossible to obtain. Whether you're pulling in Genshin Impact, Honkai: Star Rail, or Arknights, understanding the underlying probability is key to managing both your resources and your emotional "salt" levels. This tool provides a technical audit of your luck using the Geometric Distribution—the standard mathematical model for Bernoulli trials in gacha mechanics.
Our Luck Percentile Calculator accurately simulates dry spells by accounting for flat-rate probabilities and complex Soft Pity curves used by modern developers like HoYoverse and Hypergryph.
Study: When Bad Luck becomes a Statistical Anomaly
Why hitting pull 80 without a 5-star is rarer than winning the lottery.
In systems like Genshin Impact, the 0.6% base rate suggests that a player has a 61.3% chance of not pulling a 5-star by pull 73. However, the implementation of "Soft Pity" at pull 74 significantly alters the bell curve. Our data suggests that reaching pull 80 puts you in the bottom 5% of unlucky players globally. If you reach pull 85, you are experiencing a 1-in-20,000 statistical anomaly.
Before you tilt-pull, we recommend auditing your upcoming requirements with our Pity Carryover Tracker. If you're wondering if your gear luck is as bad as your pull luck, use the Artifact Grader to see your roll efficiency.
Tactical Luck Management Checklist
- Pity Buffering: Always assume the 90th percentile of unluckiness when planning a budget.
- Stop-Loss Thresholds: Use our Loot Probability tool to find your optimal "quit point" for non-pity items.
- Currency ROI: Audit the real-world value of your "guarantee" with the Currency Value Calc.
- Emotional Discipline: Understand that unluckiness is not a debt the game "owes" you back—it's simply data.
The "Law of Large Numbers"
In the short term, gacha luck is erratic and often feels "rigged." However, over thousands of pulls, most players will settle near the game's published Consolidated Rate. Our tool allows you to input your total pull history to see if your lifetime luck is actually as bad as your recent dry spell suggests.
By analyzing datasets from community trackers like Paimon.moe and Star Rail Station, we can confirm that while outliers exist, they are mathematically finite.
Probability Myths vs. Reality
- 01. The Ritual Fallacy: Locations or emotes have 0% impact on server-side RNG seeds.
- 02. The "Due" Myth: You are never "due" for a win. Each pull is independent unless a pity curve is active.
- 03. Seed manipulation: Most modern games use cryptographically secure PRNGs that prevent client-side manipulation.
Gacha Luck FAQ
What is a "Good" luck percentile?
Any percentile above 50% means you are luckier than the median player. Reaching 90%+ puts you in the "RNG God" category.
Does 10-pulling increase luck?
No. A 10-pull is simply 10 individual pulls processed at once. It does not mathematically increase 5-star (SSR) probabilities.
How does Soft Pity work?
Soft Pity is a hidden mechanic where the success rate increases by a fixed percentage (e.g., +6%) for every pull after a certain threshold (e.g., 74).
Is my account "cursed"?
Mathematically, no. "Cursed" accounts are simply the 1% tail-end outliers of a massive global dataset. Every pull reset is a fresh start.
