Why exact math matters

Most pull advice is folklore ("90 pulls = one 5★") or opaque simulators. Soft pity makes gacha probability genuinely unintuitive: the difference between pity 20 and pity 60 with the same budget can be the difference between a coin flip and near-certainty. We compute the full distribution over every pity-and-guarantee state, exactly, in your browser — nothing uploaded, nothing tracked.

Season windows are when planning matters most: Genshin 7.0 "Snezhnaya" lands August 12, 2026, Star Rail 4.5 follows in late August. The planners carry those dates as presets.
