DuckDice review: check dice odds and reproduce a round
Start a DuckDice review with the dice settings you care about. Record the win threshold, the displayed chance and the gross payout multiplier. At a 50% win chance, a hypothetical 1.98× gross payout implies 99% theoretical return before fees. Compare the same chance across sites.
Inspect fairness and auto-bet separately
If the game supports round verification, look for the server commitment, client seed and nonce, then follow the documented method on one completed round. Check whether auto-bet changes the stake after a win or loss and where you can stop it. Verification does not change the size of an automated wager.
Confirm what a low balance can do
Compare the minimum bet with the minimum withdrawal on the coin you would use. If faucet credits are offered, check whether they are practice-only or can convert to a withdrawable balance.
