PROTOCOL.777 / AUDIT METHODOLOGY
Every casino you find in slot 777 Vault passed three independent audit layers. Not marketing claims — measurable, verifiable standards run by us, not them.
SCORING / COMPONENT BREAKDOWN
The composite score is a weighted average of five criteria across the three audit layers.
| Criterion | Audit Layer | Weight | Method |
|---|---|---|---|
| RNG Distribution Quality | Layer 1 — RNG | 30% | Chi-squared test, 100k+ simulated rounds |
| Provably Fair Verification | Layer 2 — Provably Fair | 25% | SHA-256 hash chain independent reproduction |
| RTP Accuracy (Measured vs Claimed) | Layer 3 — RTP Accuracy | 20% | 30-day rolling deviation tracking, ±1% threshold |
| Crypto Payout Speed | Layer 1 — RNG / Infrastructure | 15% | Timed withdrawal tests across 3+ crypto assets |
| VIP / High-Roller Program Value | All Layers | 10% | Rakeback modelling, level-up requirements, cashback rate |
No casino can pay to improve its 777 score or vault ranking. Affiliate commission is earned on successful referrals after a casino passes the audit — not before, and not in exchange for a higher score. Casinos are reviewed on the same criteria regardless of whether they have an active affiliate agreement with situs slot 777. Casinos that fail any of the three audit layers are excluded from the vault entirely and listed separately.
PROCESS / HOW AN AUDIT WORKS
We run 100,000+ simulated rounds through each casino's declared RNG engine. Results are subjected to chi-squared goodness-of-fit testing. Any deviation beyond statistical thresholds triggers a fail — no exceptions, regardless of casino reputation or commission offer. We also verify whether the RNG is a genuine TRNG (hardware entropy source) or a PRNG (software algorithm), which affects score weight.
We independently reproduce and verify the hash-seed chain on every casino claiming provably fair mechanics. SHA-256 client seed + server seed + nonce derivation is checked for each game type (slots, dice, crash). We verify that the pre-image of the server seed hash was not changed retroactively after the round — the fundamental guarantee of provably fair gaming. Casinos that claim provably fair without supporting independent verification fail this layer.
We track measured RTP deviation from advertised figures over 30-day rolling windows across game categories (pokies/slots, table games, crash, dice). A tolerance of ±1% from advertised RTP is the pass threshold. A casino advertising 97% delivering 93% fails. A casino advertising 96% delivering 95.1% passes. Scores update monthly. Casinos can improve their RTP score over time — but cannot pay to improve it.
All three audit layers are combined with the weighted scoring table above. A composite score of 8.0+ qualifies a casino for slot 777 Vault. Casinos scoring 7.0–7.9 are listed on the watchlist. Those below 7.0 or failing any single layer entirely are excluded. Scores and rankings update every 30 days. The audit process is re-run annually in full, and on-demand if significant changes to a casino's platform are detected.
