# CrashMath 10,000-round simulation

**File:** `crashmath_10000_rounds_dataset.csv`, 10,000 crash rounds generated with HMAC-SHA256 from a public server seed and client seed (`crashmath_public_entropy_2026`), nonces 1 to 10,000.
**What it is:** a simulation of the provably fair crash algorithm. The rounds were not recorded at a live casino and do not come from any operator.
**Verify:** every `hmac_sha256` value can be recomputed from `server_seed`, `client_seed` and `nonce`; `python crash_simulation_summary.py` checks all rows and writes `crash_simulation_summary.json` (multiplier distribution, instant crashes, flat-stake results by cash-out target).
