Casino Terms Every New Player Should Know

Casino terms are the words you see on game screens, in promotions, and in player chats. The most useful ones explain how a game pays, like RTP, house edge, and volatility. Others explain how an offer works, like free play and playthrough. BitSpinWin is a social online casino that gives you access to platforms such as Vegas X and Orion Stars. Below, we group casino terminology, each with a quick example.

Basic Casino Terms for Beginners

• RTP (return to player): The share of all stakes a game is built to pay back over millions of plays. A 96% RTP slot aims to return about $96 per $100 staked in the long run. It isn’t a forecast for one session, and our guide here explains what RTP really measures.
• House edge: The flip side of RTP, so it’s 100% minus RTP. That same 96% slot has a 4% house edge. Here’s a deeper look at house edge.
• Volatility: How a game spreads out its wins. Low volatility means smaller wins more often, while high volatility means longer gaps and bigger hits. Learn more about volatility in slots.
• RNG (random number generator): The software that picks every result. Each spin is independent, so the last one doesn't affect the next.
• Paytable: The information screen that shows what each symbol pays and how features trigger. On BitSpinWin, the Sizzling Hot Deluxe has a 95.66% RTP and medium volatility.

​

• Bankroll: The total you set aside for play. If your bankroll is $50, that’s your limit.
• Session: One stretch of play, from your first spin to your last.

Slot Machine Terms

• Reels and rows: Reels are the columns that spin, and rows run across them.
• Paylines and ways: Paylines are fixed paths where matching symbols have to land. Ways games pay for matching symbols on neighboring reels from the left instead. A 5x3 grid gives 243 ways.
• Wild: A symbol that stands in for others to finalize a win. Yet, it often can’t replace scatters.
• Scatter: A symbol that pays or triggers a feature wherever it lands. Three or more often start free spins.
• Multiplier: A feature that boosts a win. With a 3x multiplier, a $2 win becomes $6.
• Free spins and bonus rounds: Extra spins the game awards. A bonus round is any special feature that breaks away from regular spins.
• Progressive jackpot: A prize that grows with every bet across linked games until someone wins it.
• Megaways: A mechanic created by Big Time Gaming. Each reel shows two to seven symbols per spin, for up to 117,649 ways to win.
• Hold and Win: A round triggered by a set number of coin symbols. Coins lock in place, and you usually get three respins that reset whenever a new coin lands. Our guide to the Hold and Win feature covers the jackpot tiers.

Keno and Fish Table Terms

In keno, you pick spots, and the game draws the winning spots. The pay table shows what each catch count pays, and the draw is the random pick itself. In Fireball Keno, you pick from 1 to 80, and the game draws 10 balls.

 

On fish tables, the cannon level sets the cost of each shot, and higher levels fire stronger shots. Boss fish are big, hard-to-catch targets with the highest payouts. Multiplier fish carry a set multiplier. For more, check out our fish table basics guide for more examples.

Casino Bonus Terms

• Sign-up bonus: A reward for opening a new account. The BitSpinWin sign-up free play is $20. It lands in your Bonus Wallet once you verify your identity with a photo ID and selfie.
• Free play: Bonus credit you can use on games without touching your own deposit.
• First deposit bonus: Extra credit on your first deposit. BitSpinWin offers 50% plus $10 in free play when you deposit into a game account.
• Reload bonus: A bonus on later deposits. BitSpinWin matches your 2nd and 3rd deposits at 20%. You also get $15 in free play on the 2nd and $20 on the 3rd, which requires a minimum deposit of $40. The 4th and 5th get 10%.
• Loyalty level: Your tier in a rewards program. BitSpinWin’s User Level has 12 tiers, from Copper to Elite. Higher levels multiply the points you earn on deposits.
• Playthrough (wagering requirement): How much you need to play before bonus funds count as eligible under the terms. A 3x playthrough on $20 means you need to play $60. See playthrough rules in practice for more.

Online Casino Terms

• Platform: A separate game system with its own lobby and titles. BitSpinWin offers more than 30 platforms, including Fire Kirin, Juwa, and Game Vault.
• Lobby: The main menu where a platform lists its games.
• Username: The name tied to your account, which you use to log in.
• Demo mode: A practice version of a game that doesn’t use your balance.
• Auto play: A setting that runs spins for you. Fireball Keno has a similar Quick Pick that chooses your numbers.
• Crypto address: The string of letters and numbers that tells a network where to send coins.
• Network confirmation: The moment a blockchain records your transaction in a block. Each new block adds another confirmation.

Casino Slang and Lingo

• High roller: A player who consistently bets far more than most.
• Whale: The top tier of high rollers, the players casinos court hardest.
• Grinder: Someone who sticks to small stakes and plays long, patient sessions.
• Dry spell: A long stretch without a meaningful win.
• Hot and cold machines: Player talk for slots on a winning or losing run. The idea that a game is “due to hit” is a myth. Every result comes from the RNG, so a quiet slot is never closer to paying.

FAQ

What does RTP mean in a casino?

RTP stands for return to player. It’s the share of all stakes a game is designed to pay back over a huge number of plays. A 96% RTP doesn’t promise $96 back from your $100 tonight. Treat it as a long-term average, not a session forecast.

What is a paytable?

A paytable shows what each symbol, line, or keno catch pays. It also explains how features like free spins trigger. Check it before you play, because two games that look alike can pay very differently. You'll usually find it behind the game’s info button.

What does house edge mean?

House edge is the built-in percentage a game keeps over time. It’s simply 100% minus the RTP, so a 96% RTP game has a 4% house edge. Like RTP, it only shows across a huge number of plays. It’s one of the casino terms and phrases you should learn first.

What is playthrough?

Playthrough is how much you need to play before bonus funds become eligible under an offer’s terms. For example, 5x on a $10 bonus means you need to play $50.
