When your affordable spins plus current pity progress exceed the pity threshold, acquisition becomes deterministic. Until that line, the engine applies the standard binomial distribution.

For a 5% drop rate with 12,500 Coins at 500 per crate, you get 25 spins. The probability of at least one success across 25 independent trials is 1 − (0.95)²⁵ ≈ 72.3%.
