Frequently Asked Questions
It is a mechanic that guarantees a rare drop after a certain number of failed attempts. It ensures that no player goes "Infinite" without a reward.
In most titles (like Hoyoverse games), pity carries over between the same type of banner (e.g., Character Event Banner to the next Character Event Banner).
Hard Pity is the "Absolute Guarantee" (e.g., 90 pulls). Soft Pity is the "Probability Spike" that happens shortly before (e.g., pull 74-89).
Because the banner features a "Featured" item and a pool of "Standard" items. The first rare drop is a coin flip. If you lose, the next is 100% guaranteed.
Mathematically, the odds are identical. However, single-pulling lets you stop immediately when you hit the drop, potentially saving spare resources.
With Soft Pity active, the average pull count is ~76, which equates to roughly $160-$180 in real-world currency depending on bundle rates.
No. For security and privacy, we do not store your pull data. We are a "Simulator" and "Calculator," not a permanent log-book.
No. Some countries (like Belgium) have banned them entirely or strictly regulated them as gambling due to the randomized nature of the rewards.
To get 7 copies (C0 to C6), you need to calculate the worst-case (1,260 pulls) vs. the statistical average (~650-700 pulls).
The incorrect belief that if you haven't won in 80 pulls, the next one is "more likely" to win (unless a pity system is explicitly active).
