Buy feature meaning: a buy feature, also called a bonus buy or feature buy, lets you pay a one-off price, set as a multiple of your stake, to start a slot's bonus round straight away instead of waiting for it to trigger. It costs far more than a normal spin, and it doesn't remove the house edge.
A buy feature skips the base game and starts the bonus round for a fixed price.
The price is a multiple of your stake, so one buy can equal dozens or hundreds of spins.
The bonus can return less than the price paid; nothing about the purchase makes a profit likely.
Casino bonus terms often cap your bet, and some say a buy counts toward that cap.

Buy feature meaning in plain terms
Normally you reach a slot's bonus round by landing trigger symbols, which may take a long run of spins. A buy feature puts a button on the screen that charges a set price and launches the feature right away. You see the price before you confirm, and it scales with your stake: if the stake doubles, so does the price.
Some games offer a softer version called a bonus bet. Instead of buying the round outright, you pay a higher stake per spin in return for a better chance of triggering the feature. Both options sit in our casino glossary, and both change how fast money moves through the game.
How a slot bonus buy works
Set your stake per spin; the buy price is calculated from it.
Open the buy option and read the price and the feature you'll get.
Confirm; the full price leaves your balance in one go.
The bonus round plays out under its normal rules.
Winnings are paid at the end; they may be more or less than the price you paid.
Prices and rules differ by game, and the help screen is the only reliable source. Some studios publish a separate RTP for the buy option, which can differ from the base game. Where that isn't published, assume nothing better than the game's headline RTP.
What a buy feature costs: the dollar math
To show the scale, take a hypothetical price of 100x the stake (real prices vary by game). At a $1.00 stake, one buy costs $100, the same as 100 normal spins, gone in a single click. At a 96% RTP, the long-run average return on $100 is $96, so the expected cost is about $4 per buy. A single buy, though, can return $10 or $400; the spread is very wide.

The expected cost matches the normal spins, but the money goes much faster, and the volatility is far higher: you're compressing a long session into one result. That makes it easy to spend a budget in minutes. Our gambling budget and bankroll management guides show how to size stakes so that doesn't happen.
This is where buys cause the most trouble. Casinos cap your stake per spin while bonus funds are active. SlotoCash's bonus terms (opens in a new tab) set a $10 maximum bet per spin while a bonus is active. The terms we have don't say how a feature buy is treated there, but some casinos' bonus terms state plainly that a buy counts toward the max-bet limit. If it does, a $50 buy would break a $10 cap, and breaking a max-bet rule can void bonus winnings.
Buy feature slots at a casino with an offer via our link
We show one partner here because it's the only one whose own game list names an RTG title with a buy feature: SlotoCash's homepage (opens in a new tab) lists Coyote Cash 2. The other partners run RTG too, but we have no list naming buy-feature games there, so check the lobby. SlotoCash is offshore and isn't licensed or regulated by any US state, so there is no state regulator to complain to, and the terms are the casino's own. Check your state's law; our offshore vs state-licensed casinos guide explains the trade-offs. We earn commission from this link.

The casino's terms list 25x (deposit + bonus) wagering, a $20 minimum deposit per bonus, no max cashout and the $10 maximum bet per spin noted above, with progressive jackpot slots, table games and video poker excluded by default. The package on its site differs from our link's headline, so the terms shown at sign-up apply.

Frequently asked questions
What does buy feature mean on a slot?
It means paying a one-off price to start the slot's bonus round immediately, rather than waiting for trigger symbols. The price is a multiple of your stake, shown before you confirm. The round then plays out normally and may return more or less than you paid. See bonus round meaning and our Coyote Cash 2 review for an RTG game listed with the option.
Is buying a slot bonus worth it?
Not in terms of expected value: the house edge still applies, so on average you get back less than you pay. What a buy changes is speed and volatility, turning many spins into one large outcome. If you enjoy the feature and the price fits your budget, that's a personal choice, but it isn't a way to profit. Read house edge meaning and casino math basics.
What is the difference between a buy feature and a bonus bet?
A buy feature charges a lump sum to start the bonus round right away. A bonus bet raises your stake per spin in return for better trigger chances, so you still spin and may still wait. RTG titles such as Shelltastic Wins and Persian Treasures are listed with both. See our Shelltastic Wins review and volatility meaning.
Can I use a buy feature with bonus money?
Sometimes, but it's risky. Casinos cap bets while a bonus is active, and some state in their terms that a feature buy counts toward that cap; SlotoCash's cap is $10 per spin. A buy priced above the cap could void bonus winnings. Ask support in writing first. See max cashout meaning and our how to read casino terms guide.
Does a bonus buy have a different RTP?
It can. Some studios publish a separate return for the buy option, which may be higher or lower than the base game. For the RTG titles in our data, no separate buy RTP is published, so the safest assumption is the game's headline RTP. Either way, it's below 100%. See RTP meaning and how slot RTP works.
Why do some casinos restrict bonus buys?
Because a buy concentrates a lot of stake into one action, it can clash with bonus rules such as max-bet limits, and it moves money very quickly. Casinos set their own rules on this, so check the bonus terms and excluded-games list. Fast spending also deserves a pause: our chasing losses guide and deposit limit meaning entry can help.
Does a bonus buy count toward the max bet at Miami Club Casino?
Yes, Miami Club's bonus terms say a buy-bonus purchase counts toward its bet limits, which are $2 per payline on slots and $10 for any single wager while a bonus is active. So any feature buy priced above $10 would breach the rule and could put bonus winnings at risk. Miami Club runs WGS software rather than RTG, so its buy options differ from the titles listed here. Its Terms of Use (v2.1, section 1.6) list the US as prohibited, while the site owner's affiliate program confirms US players are accepted; confirm at sign-up. See the Miami Club Casino review and Miami Club slots page.
Which RTG slots have a buy feature?
Third-party catalog data lists a buy feature on RTG titles including Coyote Cash 2, Escape the North, Alien Wins, Medieval Crusades, Sword of the Elements, Fortunes of Olympus, Shelltastic Wins, Persian Treasures and Doragon's Gems. Ronin – Quest of Honor, Fortune of Olympus and Sneaky Santa are listed with it too. Escape the North, Shelltastic Wins, Persian Treasures and Doragon's Gems also have a bonus bet option. Which titles a casino carries varies, so check the lobby. Our Escape the North review and RealTime Gaming page cover the studio's newer games.
Is a bonus buy the same as bet max?
No, they're different controls that both raise how much you spend. Bet max sets your per-spin stake to the game's ceiling, and you keep spinning at that level. A bonus buy charges one lump sum, priced as a multiple of your current stake, to start the feature right away. Either one can break a casino's max-bet rule during bonus play: a $10 cap is exceeded by a $25 max-bet spin or by a $50 buy alike. Neither changes the odds. Our bet max entry and max cashout rules page explain the related bonus terms.
Can I buy the bonus in Coyote Cash 2?
Yes, Coyote Cash 2 is listed in third-party catalog data with a buy feature, alongside Hold and Win, a cash collector, free spins, sticky symbols and fixed jackpots. The 2026 RTG release uses a 5x3 grid with 243 ways, is described as medium volatility and lists a 2,000x max win. No RTP was found for it, so the buy's expected cost can't be worked out from published figures. SlotoCash's homepage names Coyote Cash 2 among its games. Check the buy price on screen before confirming. Our Coyote Cash 2 review and SlotoCash review have more.
What is the RTP of the Medieval Crusades buy feature?
No separate buy RTP is published for Medieval Crusades, so the safest assumption is the game's listed 96.25%. On that basis, a $50 buy has an expected cost of about $1.88, and a $100 buy about $3.75, but the result of any single buy can be far higher or lower. The game is listed as high volatility with a 50,000x max win, a free spins mode choice and a free spins multiplier, so swings are large. Some studios publish a different RTP for their buy option, which is why the help screen matters. Our Medieval Crusades review and how slot RTP works guide explain the math.
Does a buy feature guarantee a win?
No, a buy only guarantees that the bonus round starts, not that it pays back the price. Using a hypothetical 100x price at a $1 stake, a $100 buy can return $10, $400 or anything in between, and the house edge means it returns less than the price on average. Several buys in a row can lose most of their cost. Treat the price as money spent, and decide in advance how many buys, if any, fit your session budget. Our what to do after a big win guide and can you win real money online answer put outcomes in context.
Is buying slot bonus features online legal in Illinois?
No, Illinois doesn't license any real-money online casino, so buying features at one falls under the same law as any other online casino play. The Illinois Gaming Board says state law prohibits operating internet sites that allow gambling, and an iGaming bill, HB 0007, was in committee according to a third-party tracker. Offshore casinos, including SlotoCash, aren't licensed by Illinois or any other state, so there's no state route for complaints. Our Illinois online casinos hub and can I play online casinos in Illinois answer explain the state's law.
