A Japanese toolkit for estimating pachinko expected value, border rates, hourly returns, spin rates, hit probabilities, leftover balls, and bankroll composition.

ぱっちー models individual machines through prize distributions, rounds, balls awarded, and transitions between jackpot and RUSH states rather than treating the machine as a black box. It also includes calculators for Tokyo’s 28-ball exchange rate and fragmented play sessions, while warning that its long-run estimates do not guarantee short-term results.
