No bets yet — set a seed pair and verify.

Outcomes use the same HMAC-SHA256(serverSeed, "clientSeed:nonce:cursor") stream as the Shuffle tools on /verify. Dice is floor(float × 10,001) ÷ 100, as on Shuffle. Crash is replayed from your seed pair — it is not a hash-chain game on Shuffle. Plinko draws one float per row, as Shuffle’s own provably-fair panel does, and pays Shuffle’s bucket tables for 8 to 16 rows at Low, Medium and High risk, read from Shuffle’s Plinko game. Keno and Wheel tables that Shuffle does not publish are CasinoDrop’s own 1%-edge prices. Blackjack settles the opening two-card hands (3:2 blackjack, push returns the stake). Blitz pays Shuffle’s own table, 0.98 ÷ the chance that every pick is a different card. This is not a prediction and not a real-money wager. Only bets placed before you rotated the seed pair can be checked.
