⚠ CRITICAL AUDIT FINDINGS (v1.0 — NOW RESOLVED)
BUG #1: Double-Dipping House Edge
Original formula if (r < 0.05) return 1.0; return 0.95/r applied a 5% instant-crash override ON TOP of the formula's natural ~5% instant-crash rate. Effective RTP was ~90%, not 95%.
FIX: max(1.00, 0.945 / r) — single formula, no special case. RTP = 94.5% base.
BUG #2: Elimination = Total Loss (Strategy-Dependent RTP)
Zone eliminations caused total bet forfeiture. A player targeting 3x (past Zone 1) had RTP = 84.15%. Targeting 5x (past Zone 2): RTP = 71.5%. This is a certification blocker.
FIX: Elimination = forced cash-out at zone multiplier. Mathematical proof: conditional EV at any multiplier m equals m. Therefore forced cash-out preserves the base RTP.
ISSUE #3: No Provably Fair Implementation
Game used Math.random() — not auditable. Provably fair specification provided below for production implementation.

House Edge
| Component | Allocation | Type | Description |
|---|---|---|---|
| Base RTP | 94.50% | Guaranteed | Cash-out payouts via crash formula |
| Survivor Reward Pool | 0.50% | Conditional | Awarded to Last Survivor per round |
| Progressive Jackpot | 1.00% | Pooled | Accumulates, awarded periodically |
| House Edge | 4.00% | Operator | Commercial terms negotiated separately |
| TOTAL | 100.00% | — | All wagers accounted for |
RTP VALIDATION
Total Player RTP = 94.50% + 0.50% + 1.00% = 96.00% — within target range of 96.0% ± 0.25%. ✓
Assessment against GLI-19, iTech Labs, BMM Testlabs, and eCOGRA standards.
| Requirement | Status | Notes |
|---|---|---|
| RTP ≥ regulatory minimum | ✅ PASS | 96.0% exceeds most jurisdictions (typically ≥ 85-92%) |
| Strategy-independent RTP | ✅ PASS | Proven: EV = 0.945 for any cash-out target |
| Elimination preserves RTP | ✅ PASS | Forced cash-out model — EV-neutral |
| Provably fair RNG spec | ⚠️ SPEC READY | HMAC-SHA256 framework defined; needs production implementation |
| RNG independence | ✅ PASS | Each outcome uses unique HMAC input |
| Progressive jackpot RTP | ⚠️ REQUIRES CONFIG | Must-hit-by ceiling recommended |
| Audit trail / logging | ⚠️ NEEDS IMPL | Server seeds, results must be logged and verifiable |
| Game rules clarity | ✅ PASS | Elimination = forced cash-out clearly communicated |
| Max win cap | ⚠️ RECOMMENDED | Consider a max multiplier cap (e.g., 10,000x) for risk management |
| Volatility classification | ✅ PASS | Medium-High volatility — standard for crash games |
