# Affiliate
A partner who earns a commission on the GGR generated by the players they refer. Duel's public affiliate program pays competitive RevShare with no negative carry-over.
Duel Casino Glossary
Thirty-nine terms every Aussie Duel player bumps into before their first cash-out: pokies rakeback maths, RTP versus volatility, KYC thresholds in A$, hash chains, parlay variance and network fees when you send on the wrong chain. Chuck it in your bookmarks; the wallet receipts make a lot more sense once you've had a read.
# AML (Anti-Money Laundering)
The compliance framework that requires operators to flag dodgy transaction patterns. AML is why structured deposits with no betting get held, and why an A$20k+ payout triggers a manual review even on a spotless account.

# Bonus Lock
A state where your balance is tied up in bonus funds and can't be withdrawn until the wagering is cleared. The opposite of cash. Duel doesn't use bonus-locked balances; rakeback and rebates always land as cash.
See also: Wagering Requirement
# Crash
The multiplier climbs until a randomly chosen point, then crashes. Cash out before it goes and you keep the multiplier; a tick too late and you lose the stake. RTP at Duel is 99%, backed by a verifiable hash chain.
# Crypto Address
The public string used to receive funds on a given chain. Always match the sender's chain to the recipient's: USDT-ERC20 sent to a USDT-TRC20 address is gone for good.
# Deposit
Topping up your account. 13 chains, including BTC mainnet, Lightning, ETH, USDT (5 networks), USDC (5 networks), TRX, SOL, BNB, TON, DOGE, BCH and XRP. Prefer Aussie dollars? Buy crypto with an AUD on-ramp via card, Apple Pay or PayID. Credit lands after the first confirmation on the relevant chain.

# Deposit Limit
A daily, weekly or monthly cap you set on your own account, in A$. New or lower limits apply instantly; easing a limit is held back by 24 hours by design.
See also: Self-Exclusion
# Dice
An over-under prediction game with an adjustable win chance. RTP sits at 99% across every target; the house edge is the same whether you back 2.00× or 9,900×.
# Duel Originals
Ten in-house games (Dice, Mines, Plinko, Crash, Limbo, Keno, Hi-Lo, Wheel, Groomer's Van, Beef) tuned to 99–100% RTP and provably fair from end to end.

# Freebet (Sports)
A single-use sports bet funded by the casino. A win returns the net profit only; a loss returns nothing. At Duel, freebets turn up through promo drops rather than as on-deposit bonuses.

# GGR (Gross Gaming Revenue)
The casino's take before winnings are paid out. Formula:
wagered − returned over a set window. Rakeback is worked out as a percentage of this, never of your total turnover, which is why a tight session can pay a bigger rebate than a much larger losing one.# Hash (Seed)
What you get from running a one-way function (SHA-256) over the server seed before the round. The hash goes up front, the seed is only revealed afterwards, so you can check it wasn't swapped mid-round.
# House Edge
The flip side of RTP:
100% − RTP. A 99% RTP game carries a 1% house edge. On Duel originals at 100% RTP the edge is 0%, so the casino's take comes purely from rake on player-versus-player formats and from volume on third-party pokies.# hreflang
An HTML attribute that tells search engines which language a URL is aimed at. Duel publishes hreflang for 13 locales so visitors land on the page in their own language without redirect drift.
# KYC (Know Your Customer)
The identity-check process. Duel runs an A$2,000 daily threshold: total withdrawals under that line need nothing, above it you upload a passport or driver's licence plus a 30-second selfie video. Median approval is under 24 hours.

# License
Regulatory approval that lets an operator process bets legally. Duel runs under Anjouan ALSI-202411026-FI1, audited yearly for game fairness and AML controls. It's an offshore licence, not an Australian one, so local consumer protections don't apply.

# Magic Link
A single-use email link that signs you in without typing a code. It expires after 30 minutes and only works in the same browser session that asked for it.
See also: TOTP / 2FA
# Memo / Tag
A required secondary identifier for chains like XRP and TON. Leave the memo off and the deposit still reaches the wallet but can't be matched to your account, which means a manual reconciliation.
See also: Deposit
# Mines
A sweeper-style grid where you flip tiles to grow your stake until you hit a mine. Multipliers scale with the remaining safe tiles divided by total tiles, minus a 1% house edge.
See also: Duel Originals
# Network Fee (Gas)
The on-chain transaction fee paid to miners or validators. Duel wears the fee on withdrawals; on deposits you pay the sending wallet's fee. TRC-20, Lightning and L2s are usually the cheapest.
# Nonce
A counter that climbs with every bet inside the same seed pair. Verification scripts feed in
(server_seed, client_seed, nonce) to reproduce a result, so you can audit any bet in your history.# Originals Rebate
A weekly 5% rebate on your stake on Duel originals, paid at the end of the week if you finished down. It's separate from pokies rakeback because originals already run at zero edge.
# Orphan Bet
A bet whose outcome was confirmed but whose payout didn't credit. It's caught by reconciling the seed/nonce log against the wallet ledger, and auto-recovered within five minutes.

# Parlay (Accumulator)
A sports bet, a multi in Aussie terms, that combines two or more selections; every leg must land for the ticket to pay. It multiplies the odds and the variance alike.
# Plinko
A pin-and-ball game. A token drops through rows of pegs and settles in a slot carrying a payout multiplier. You can dial the payout spread anywhere from low to extreme volatility.
# Provably Fair
Cryptographic proof that a result was locked in before you placed the bet. The casino commits a hashed server seed, you supply a client seed, and the outcome is worked out deterministically from both. Anyone can verify it after the round by re-running the same hash, no trust required.

# Rakeback
A rebate paid back to you as a percentage of the casino's gross gaming revenue (GGR). At Duel, pokies rakeback is 50% of GGR, paid in real time, with no wagering and no max cash-out. The pokies row in your wallet ledger lists each one-minute window on its own.

# RevShare
An affiliate commission model paying a percentage of player GGR for the life of the account. The opposite of CPA, which pays a fixed amount per qualifying sign-up.
# RNG (Random Number Generator)
The algorithm that spits out a stream of pseudo-random numbers. Reputable casinos run audited HMAC-SHA256 or ChaCha20 RNGs. “Provably fair” adds the cryptographic guarantee that the casino didn't pick the seed after seeing your bet.
# RTP (Return to Player)
The theoretical long-run percentage a game hands back to players. Duel originals are tuned to 99–100% RTP, against the roughly 96% baseline on most pokies. RTP only holds up over the long haul; across 100 spins it tells you next to nothing, across 100,000 it settles.

# Seed
The input string that drives the random number generator. Provably-fair games use three: a hashed server seed committed before the round, a client seed you can rotate whenever you like, and a nonce that ticks up with each bet.
# Self-Exclusion
A player tool to lock the account for a set period (24h, 7d, 30d or permanent). Duel actions cooling-off requests immediately and won't send reactivation marketing to excluded accounts. For a block across Australian-licensed sites, sign up to BetStop, the national self-exclusion register.

# Sportsbook
The bookmaking side of the casino. Duel covers 50+ sports and around 15,000 markets a day, with most lines refreshed every 1–2 seconds over WebSocket.

# TOTP / 2FA
A time-based one-time password used as a second factor. Duel supports TOTP through any standard authenticator app (Aegis, 2FAS, Authy). 2FA guards withdrawals and password resets.

# Variance
Volatility's statistical sibling. In gambling maths, variance is the standard deviation of round outcomes, squared. It shows how hard your bankroll can swing inside a session, and it's why the “theoretical” RTP rarely matches the RTP you actually cop on the night.
# Volatility
How far a game's results swing from its average. High-volatility games pay rarely but pay big; low-volatility games trickle out small wins. RTP and volatility are separate things: two 96% RTP pokies can have wildly different cash-out rhythms.
# Wagering Requirement
The multiplier you have to bet through before bonus funds can be withdrawn. Duel rakeback has 0× wagering: it lands as cash. Plenty of other operators charge 25–40× the bonus, which on an A$100 bonus means A$2,500–4,000 of turnover before you can cash out.
# Wallet Ledger
A live, line-by-line record of every credit and debit on your account: bets, payouts, rakeback, rebates, deposits and withdrawals, with timestamps and tx-hashes where relevant. You can export the lot as CSV.
# Withdrawal
An on-chain payout of your account balance. Duel auto-approves anything under A$20,000, with a median time from confirm to broadcast of about three minutes. The network fee is covered by the casino.
