Crypto Casino Glossary: 31 Terms You Need to Know

If you’re new to online casinos or just starting to explore crypto gambling, it’s easy to feel overwhelmed by unfamiliar jargon and casino terms. From bonuses and wallets to game mechanics and blockchain features, the language alone can be confusing. This crypto casino glossary is designed to simplify those terms in plain English, helping you understand what you’re seeing before you place a bet.

Below, you’ll find a glossary that organizes the most important terms in alphabetical order, making it easier to reference specific concepts as you encounter them.

Altcoin

Short for “alternative coin,” this refers to any cryptocurrency other than Bitcoin. In crypto casinos, altcoins like ETH, LTC, SOL, or DOGE can be used for deposits, bets, and withdrawals.

---

Bankroll

The total amount of money or crypto you set aside specifically for gambling. Managing your bankroll properly helps you control losses and play sustainably, especially in volatile crypto environments where asset values can change quickly.

---

Blockchain

A decentralized, public digital ledger that records all crypto transactions. In crypto casinos, blockchains ensure transparency, security, and immutability. Deposits, withdrawals, and sometimes game outcomes can be verified on-chain.

---

Bonus

A promotional reward offered by crypto casinos, such as welcome bonuses, deposit matches, free bets, or free spins. Bonuses usually come with wagering requirements, which must be met before winnings can be withdrawn.

---

Crash Game

A popular crypto-native casino game where a multiplier increases from 1.00x upward until it randomly crashes. Players must cash out before the crash to win. If the game crashes first, the bet is lost.

---

Crypto

Cryptocurrencies like BTC are virtual assets that use cryptography for security and operate on blockchain. They allow for fast and secure transactions without the need for banks.

---

Crypto Faucet

A reward system that dispenses small amounts of BTC or other cryptocurrencies. Players can use these free funds to place bets and try out games in a casino without making a deposit.

---

dApp (Decentralized Application)

An application that runs on a blockchain rather than centralized servers. Some crypto casinos operate as dApps, allowing players to interact directly with smart contracts instead of traditional casino backends.

---

Deposit Confirmation

The number of blockchain confirmations required before your crypto deposit is credited. For example, Bitcoin casinos typically wait 2–6 confirmations to ensure the transaction is irreversible.

---

Fiat Currency

Government-issued money such as USD, EUR, or JPY. Many crypto casinos support fiat alongside crypto, though crypto deposits usually offer faster withdrawals and fewer identity checks compared to fiat-based transactions.

---

Gas Fee

The transaction fee required to process actions on a blockchain, especially Ethereum. When depositing or withdrawing from a crypto casino on Ethereum, higher network congestion can increase gas fees significantly.

---

Hash

A cryptographic output used in blockchain transactions and provably fair systems. In crypto casinos, hashes help verify that game outcomes were pre-determined and not altered after bets were placed.

---

House Edge

The mathematical advantage a casino has over the player. If a game has a 2% house edge and you bet $100 repeatedly, the casino expects to earn $2 over time.

---

KYC (Know Your Customer)

A verification process requiring identity documents. Many crypto casinos advertise “No-KYC gambling“, meaning players can gamble and withdraw without submitting personal information, using only a crypto wallet.

---

Liquidity

The ability of a casino or betting market to handle large bets without impacting odds or payouts. High liquidity ensures smoother betting, especially for live sports betting and high-roller wagers.

---

Multiplier

A number that determines winnings based on the original stake. A 5x multiplier on a $20 bet returns $100 if you win. Multipliers are common in Crash games and certain slot mechanics.

---

No Deposit Bonus

A bonus given without requiring a deposit. These are rare in crypto casinos and often come with strict wagering limits, low maximum withdrawals, or game restrictions.

---

Odds (Decimal)

The most common odds format in crypto sportsbooks. Odds of 2.50 mean a $10 bet returns $25 (including your stake). Decimal odds make payout calculations straightforward and transparent.

---

Provably Fair

A fairness system used by crypto casinos that allows players to verify game results mathematically. It uses hashes, server seeds, and client seeds to prove outcomes weren’t manipulated.

RNG (Random Number Generator)

A software program used in slots to generate random outcomes for every spin, ensuring fairness by making results unpredictable and unaffected by previous plays.

RTP (Return to Player)

The theoretical percentage of wagers returned to players. A slot with 96% RTP pays back $96 for every $100 wagered in the long run.

Satoshi

The smallest unit of Bitcoin, equal to 0.00000001 BTC. Crypto casinos often display wagers and balances in sats for micro-betting and precise bankroll control.

---

Seed (Client & Server)

Values used in provably fair systems. The server seed comes from the casino, while the client seed comes from the player. Together, they generate random outcomes that can be independently verified.

---

Slot Paytable

The slot paytable shows symbols, payout values, winning combinations, and bonus features, helping players understand paylines, wilds, and bonus mechanics.

---

Stablecoin

A cryptocurrency pegged to a stable asset, usually the US dollar. Using stablecoins like USDT or USDC helps players avoid crypto price volatility while betting.

Tokens

Digital assets used within a specific ecosystem. Some crypto casinos issue native gambling tokens that offer benefits like staking rewards, cashback, fee discount, or exclusive bonuses.

---

Wallet

A tool for storing and managing crypto assets. Wallets can be software-based (mobile or desktop) or hardware devices. Connecting a wallet allows players to deposit, bet, and withdraw directly.

Wagering Requirement (Rollover)
