Crypto Casino Glossary

A single sportsbook bet that combines multiple selections into one. All selections must win for the bet to pay out. The odds multiply together, creating a higher potential payout than placing each bet individually, but if any selection loses, the entire accumulator loses.

A set of laws and procedures designed to prevent criminals from disguising illegally obtained funds as legitimate income. Licensed gambling operators like Duelbits are legally required to monitor transactions and may request identity verification as part of AML compliance.

A feature in games like Crash that lets you set a target multiplier before the round starts. If the round reaches your target, the system cashes you out automatically, even if you are disconnected. Contrast with manual cash-out, where you click the button yourself in real time.

The Duelbits rakeback currency. Every real-money wager you place earns Bits automatically. Bits are returned to you through four recurring claim windows — Instant, Daily, Weekly, and Monthly, each at a flat 5% rakeback rate. Bits have a 1:1 USD value.

A decentralised digital ledger that records transactions across a network of computers. Cryptocurrencies like Bitcoin and Ethereum run on blockchains. When you deposit or withdraw crypto on Duelbits, the transaction is recorded on the relevant blockchain.

When the multiplier in a Crash game stops rising and the round ends. If you have not cashed out before the bust, your bet is lost. Also called the "crash point."

The ability to settle a bet or game round before the final outcome is determined. In sportsbook, cash-out lets you take a return on an open bet before the event finishes. In Crash, cash-out means collecting your payout before the multiplier busts.

A value you set as part of the provably fair system. Your client seed is one of three inputs (along with the server seed and nonce) used to determine each game outcome. You can change it at any time between rounds.

→ See the How to Verify Fairness with Provably Fair page.

When a crypto transaction is included in a block and added to the blockchain. Different coins require different numbers of confirmations before a deposit is credited. More confirmations means the transaction is more secure.

The multiplier at which a Crash round ends. Determined by the provably fair system before the round starts. If you cash out before the crash point, you win. If you do not, your bet is lost.

Describes a platform built primarily around cryptocurrency deposits, withdrawals, and wagering, as opposed to traditional fiat-first casinos that added crypto later. Duelbits is a crypto-first platform.

The fiat currency used to show values on screen (balance, bets, payouts). On Duelbits, all balances are held internally as Duelbits coins tied to USD. The display currency is a visual conversion only, changing it does not convert your funds.
→ See Understanding Display Currencies on Duelbits page.

The internal unit of value on Duelbits. All deposits (crypto or fiat) are converted into Duelbits coins at the live exchange rate. Duelbits coins are tied to the US dollar.

A token standard on the Ethereum blockchain. Coins like ETH, USDT (ERC-20), USDC (ERC-20), SHIB, and DAI use this standard. ERC-20 transactions incur gas fees that vary with network congestion.

A promotional offer where the sportsbook boosts the odds on a specific selection above their normal level. On Duelbits, these appear as Mega Boosts and Super Boosts on featured events.

Government-issued currency such as USD, EUR, GBP, or BRL. Duelbits supports fiat deposits in selected regions through methods like PIX, Interac, Visa, Mastercard, UPI, and JCB. All withdrawals are processed in crypto.

The network fee you pay to process a transaction on a blockchain. Gas fees are paid to the network (miners or validators), not to Duelbits. Duelbits charges zero platform fees, gas fees are the only cost on deposits and withdrawals.

The process of converting data into a fixed-length string of characters using a mathematical function (e.g., SHA-256). In provably fair gaming, the server seed is hashed before a round starts. After the round, the original seed is revealed, and you can hash it yourself to confirm it matches, proving the outcome was not changed.

A sequence of hashes where each one is derived from the next. In Crash, the entire series of future round outcomes is generated in advance as a hash chain. This means every crash point is predetermined and linked cryptographically, changing any single round would break the chain and be immediately detectable.

The mathematical advantage the casino has on every bet, expressed as a percentage. For example, a 5% house edge means that for every $100 wagered collectively, the casino expects to keep $5 over time. The house edge is the inverse of RTP: a game with 95% RTP has a 5% house edge.

Sportsbook bets placed after an event has started, while it is in progress. Odds update in real time based on what is happening in the game.

A large prize pool that accumulates over time as players wager on specific games. Jackpots can be fixed (set amount) or progressive (growing with every bet until won).

Identity verification procedures that licensed operators may request. Documents can include government-issued photo ID, proof of address, and proof of fund ownership. On Duelbits, verification may be triggered at certain thresholds or at the platform's discretion.

Casino games streamed in real time from a professional studio with a human dealer. Players interact through a digital interface while watching the dealer operate a physical table. Common live dealer games include blackjack, roulette, baccarat, and game shows.

An additional identifier required when sending certain cryptocurrencies (e.g., XRP, BNB). You must include both the wallet address and the correct memo or tag, omitting it can result in permanent loss of funds.

The factor by which your bet is multiplied to calculate your payout. In Crash, if you bet $10 and cash out at 3.00x, your payout is $30.

A counter that increments by one with every bet you place under your current seed pair. The nonce ensures that every round produces a unique outcome even when the server seed and client seed remain unchanged. It is the third input in the provably fair system.

In-house games built and operated by Duelbits. All 13 Originals are provably fair. The lineup includes Crash, Dice, Mines, Plinko, Hi-Lo, Keno, Roulette, Blackjack, Dice Duels, Duel Poker, and others.

A cryptographic system that allows players to independently verify that every game outcome was determined fairly and was not manipulated. The system combines a server seed, a client seed, and a nonce through a hashing algorithm. After each round, you can verify the result yourself using the revealed seeds.
​

A system that returns a percentage of your wagered amount back to you, regardless of whether you win or lose. On Duelbits, rakeback is delivered through the Bits system: four recurring claim windows (Instant, Daily, Weekly, Monthly), each at a flat 5% rate. The maximum combined recurring rakeback is 25%.

Software or hardware that generates unpredictable outcomes. Third-party casino games (slots, live dealer) use certified RNG systems audited by independent testing agencies. Duelbits Originals use a provably fair system instead of traditional RNG.

The percentage of all wagered money that a game returns to players over time. Expressed as a percentage, for example, a game with 95% RTP returns $95 for every $100 wagered collectively over the long run. RTP is a statistical average, not a guarantee for any individual session. RTP is the inverse of house edge.

A voluntary restriction you place on your own account to prevent yourself from gambling for a set period. On Duelbits, available periods are 1 week, 1 month, 6 months, or permanent. Once applied, it cannot be shortened or reversed.
→ See the Duelbits Self-Exclusion Policy page.

A random value generated by Duelbits before each round. You receive a hashed version before the game starts, so the outcome is locked in before you bet. The original seed is revealed after the round, allowing you to verify that nothing was changed.

The hashing algorithm used in provably fair systems and in Bitcoin. It converts any input into a fixed 64-character hexadecimal string. The same input always produces the same output, but the output cannot be reversed to find the input.

A cryptocurrency designed to maintain a stable value, usually pegged 1:1 to the US dollar. Common stablecoins on Duelbits include USDT (Tether), USDC (USD Coin), and DAI.

A bonus that can be used for wagering but cannot be withdrawn as cash. Only winnings generated from the bonus (after meeting any wagering requirements) can be withdrawn. The bonus amount itself is removed from your balance at withdrawal.

A token standard on the Tron blockchain. USDT on TRC-20 is the fastest and cheapest stablecoin option on Duelbits, with near-instant settlement and near-zero fees.

An extra layer of account security that requires a time-based code from an authenticator app (e.g., Google Authenticator, Authy) in addition to your password when logging in. Strongly recommended for all Duelbits accounts.

A Duelbits sportsbook feature that pays out your football bet as a winner the moment your team leads by two goals, regardless of the final result.

The dollar value shown on screen when your display currency is set to USD. On Duelbits, all balances are internally tied to USD, so the USD display reflects your actual balance value without exchange rate conversion.

The process of confirming your identity by submitting documents to the platform. May include government-issued ID, proof of address, and source of funds documentation. On Duelbits, verification may be requested at certain account activity thresholds or at the platform's discretion.

A condition that must be met before funds can be withdrawn. On Duelbits, all deposits are subject to a minimum wagering requirement of 10% of the deposit amount. Some bonuses may have their own separate wagering requirements.

A digital tool for storing, sending, and receiving cryptocurrency. You need an external crypto wallet to withdraw funds from Duelbits. Wallets can be software-based (MetaMask, Trust Wallet), hardware-based (Ledger, Trezor), or exchange-hosted (Binance, Coinbase).

What is the difference between house edge and RTP?

They are two sides of the same coin. RTP is the percentage returned to players; house edge is the percentage kept by the casino. A 95% RTP game has a 5% house edge. They always add up to 100%.

What does provably fair mean in simple terms?

It means the game outcome is locked in before you bet, and you can check it yourself afterwards using maths. Neither you nor the casino can control or predict the result.

What is rakeback and how does it work on Duelbits?

Rakeback returns a percentage of every wager back to you automatically. On Duelbits, it works through the Bits system, four claim windows (Instant, Daily, Weekly, Monthly), each paying 5%, for a maximum combined recurring rakeback of 25%.

What is the difference between a stablecoin and a regular cryptocurrency?

A stablecoin is pegged to a fixed value (usually $1 USD), so its price does not fluctuate significantly. Regular cryptocurrencies like BTC and ETH have volatile prices that change constantly. Stablecoins on Duelbits include USDT, USDC, and DAI.
