Duel.com tools: calculate, check, and verify before you deposit
Three interactive tools we built and maintain ourselves. None of them need an account, an email, or a deposit. Use them to put real numbers behind every claim on this site before you risk your own crypto.
We may receive a commission for purchases made through affiliate links on this site. Our ratings and opinions remain independent.
All three tools
Rakeback calculator
Enter your monthly wager volume on slots and Originals. See your exact 50% cashback in dollars, not a marketing percentage.
Withdrawal speed log
Network fees and block-confirmation times for each payout method, plus how to time and verify your own withdrawal.
Provably fair verifier
Paste a server seed, client seed, and nonce to confirm a result was fixed before your bet, not chosen afterward.
Which tool do you need first?
Deciding whether Duel is worth it? Start with the rakeback calculator. The 50% wager-free rakeback is the single biggest reason to pick Duel over a bonus-driven casino, and the calculator turns your own play volume into a dollar figure you can compare.
Worried about actually getting paid? Open the withdrawal speed log. It breaks your wait into the two things that actually cause it — Duel's processing queue and the network's own confirmation time — and shows you how to time and verify a withdrawal yourself instead of taking anyone's word for it.
Not sure the games are honest? The verifier re-runs the cryptography on any Duel Originals round. If the seeds reproduce the result shown, the outcome was committed before you clicked bet.
How we keep these accurate
The calculator uses the percentages documented on our rakeback breakdown and is revised whenever Duel changes its VIP structure. The network fee and confirmation-time figures in the withdrawal log come from each blockchain's own public parameters, not from operator-run tests, see the withdrawal methodology page for how to check them yourself. The verifier runs entirely in your browser; nothing you paste leaves your device. Spot a number that looks wrong? Use our contact page (our editorial mailbox is currently being set up) and we will recheck it.
