How it works

It's tempting to assume a 1% pull will land at least once in 100 tries — but with independent trials, 100 attempts only give you about a 63.4% chance of at least one hit. The other 36.6% walk away empty-handed. This simulator rolls fresh randomness every run, just like the real game, so results differ each time you run it.

FAQ

Q. Will a 0.1% item drop if I try 1,000 times?

A. At 1,000 attempts you have roughly a 63.2% shot at one or more hits. Getting to 95%+ confidence takes about 3,000 attempts.

Q. Does this match the real game's odds?

A. Yes — it uses the same independent-trial algorithm most game servers run, so it's statistically equivalent.

Q. Does this account for pity/guarantee systems?

A. No — this is pure independent-trial probability. Pity systems vary by game, so factor them in separately.
