Gacha Probability Calculator#
The gacha probability calculator answers the question every player should ask before spending: what are my actual odds?
Enter a banner’s base rate and your planned pulls to get:
- Your real chance of at least one hit (intuition usually overestimates it)
- The chance you come away with nothing (each extra pull only multiplies failure by (1−p))
- P50 / P90 / P99 benchmarks (how many pulls 90% confidence really takes)
The tool models independent pulls without pity, and the page explains three classic intuition traps — the gambler’s fallacy, the hot-hand fallacy, survivorship bias — plus how published rates differ across CN/JP/NA servers. Do the math before you pull.
What’s Next#
The team builds tools that players actually use. Currently under evaluation:
- Build cost calculator: total material investment for a full build at current-version prices
- Grind-time estimator: natural days to level cap given daily/weekly income
- Patch diff cheat sheet: one-page numeric changes between two versions
