Evidence and scope
A full hash-only commitment was captured before the requests for eleven rounds, nonces 6 through 16, using 8, 9, 13 and 16 rows across Low, Medium and High risk. A later seed rotation disclosed the matching server seed. All eleven slots and announced multipliers reproduce. Paths shown here are calculated from the public code; the API captured slots, not full observed paths.
The disclosed nonce 16 example uses 13 rows, Low risk, slot 4 and gross multiplier 1.21092104x. The settings counter recorded before these rounds was 6; earlier bets on that seed pair are outside this capture.
Algorithm
Duel decodes its 64-character seed into 32 raw bytes. SHA-256 of those bytes checks the commitment. For each row, a fresh HMAC-SHA256 uses the same raw key and the UTF-8 message clientSeed:nonce:cursor, with cursor starting at zero. The first four bytes form an unsigned big-endian integer; its parity selects Left (0) or Right (1). The final slot is the count of Right moves.
Payout limits
The capture includes 27 base configurations for 8-16 rows and three risks, plus 191 stake-size tiers per configuration. Base-table gross RTP is about 99.9%; captured rounds report an effective edge of 0.1 percent. This does not certify zero-edge cashback, currency settlement, the denomination of tier thresholds or payouts for higher tiers.
