What you are buying

A feature buy purchases the trigger, not a result. Paying 100x in The Dog House Megaways starts the free spins exactly as three scatters would, with the same choice of sticky or raining wilds and the same random outcomes. Some games sell more than one thing: Wanted Dead or a Wild sells each of its three bonus games at its own price, San Quentin sells its enhancer cells and free spins at rising prices, and Big Time Gaming's Feature Drop lets the price fall spin by spin before you buy. The button always states what it starts and what it costs.

Price bands

Price

What it usually buys

Examples in the lobby

50x

A standard free spin round

Extra Chilli (Feature Drop start price)

75x to 100x

A standard free spin round from Pragmatic Play, Hacksaw or Push Gaming

Gates of Olympus, Sweet Bonanza, The Dog House Megaways, Sugar Rush

150x to 300x

An enhanced round: more spins, higher starting multiplier

Sweet Bonanza 1000 super buy, San Quentin mid tiers

400x to 500x and above

The top round with the best starting position

San Quentin top tier, Money Train 2 top buy, Wanted Dead or a Wild Great Train Robbery

The bands are a guide, not a rule; each game page at Feature Buy Slots prints the exact price. What the bands show is that price tracks what the round is expected to return. A 500x buy is not five times as good a deal as a 100x buy; it is a round expected to return about five times as much, minus the house edge in both cases.

Buy RTP and base RTP

Every buy has its own RTP, and studios publish it beside the base figure. In many Pragmatic Play titles the bought round returns slightly more than base play, by a fraction of a percentage point; in others it is equal; in a few it is lower. The number is in the game's information panel, and Feature Buy Slots lists both figures on every game page. Three things the pair tells you:

Ante bet: the middle option

Pragmatic Play offers a third route in most of its buy games: the ante bet, which raises the stake by 25% and roughly doubles the chance of a natural trigger. The buy button is disabled while ante bet is on. It suits players who want more bonus rounds without paying for each one, and it changes the bankroll rule: the effective stake is 1.25x, so a balance of 200 stakes becomes 160 ante stakes. Feature Buy Slots marks ante-bet games on the game page.

The lobby, by what the button does

One price, one round

Gates of Olympus, Sweet Bonanza, The Dog House Megaways, Sugar Rush and Big Bass Bonanza from Pragmatic Play, all at 100x. The simplest buys in the lobby and the place to learn the arithmetic.

Several prices, several rounds

Wanted Dead or a Wild sells Duel at Dawn, Dead Man's Hand and The Great Train Robbery separately. San Quentin from Nolimit City sells enhancer cells and free spins at a ladder of prices up to the top tier. Money Train 2 from Relax Gaming sells its respin bonus at more than one level. These are the games where the buy decision has a second layer: which round, not only whether.

A price that moves

Extra Chilli's Feature Drop starts at 50x and falls as certain symbols land, so a patient player pays less than a hurried one. Feature Buy Slots lists it on its own shelf because it is the only price in the lobby that changes while you watch.

Buy editions of classics

Dead or Alive 2 Feature Buy from NetEnt sells the three saloon rounds. EGT Digital's Buy Bonus series, 20, 40 and 100 Burning Hot, Bulky Fruits and Extra Crown, adds a button to classic fruit designs. Both shelves are for players who know the base game and want to skip it.

Bankroll rules for buying

A bought round is a single high-variance event. Its average return is close to its price; its actual return ranges from a small fraction of the price to many multiples of it. The rule that follows is about counts, not amounts: a balance should cover enough buys to reach the average. Feature Buy Slots suggests thirty buys as a floor for 100x rounds, meaning a balance of 3,000 stakes at the chosen stake, and proportionally fewer for cheaper buys. A balance that covers five buys will, more sessions than not, end before the average arrives.

Two habits keep the rule honest. Decide the number of buys before the first one, and stop at that number whatever the running total. Lower the stake rather than the count when the balance is short; a 100x buy at half the stake is still thirty buys.

Ten buys, logged

Ten purchases of the Gates of Olympus free spins at 100x each, from a demo log at Feature Buy Slots, one stake per spin, a thousand stakes spent. Returns in stakes: 41, 118, 22, 67, 209, 35, 88, 14, 156, 73. Total returned: 823. Three rounds beat their price, seven did not, and the two best rounds carried the set. That is a normal ten buys, and it shows why the rule is about counts: after five buys the log stood at 457 returned for 500 spent; after ten, 823 for 1,000. Neither figure is the average, and thirty buys would still not settle it, but ten already shows the shape: most buys lose, a few win large, and the balance has to survive the most until the few arrive.

Buy or wait

A rule of thumb that fits the lobby: buy when the base game is quiet and the buy RTP matches or beats base, wait when the base game pays and the trigger is frequent. Gates of Olympus and Sweet Bonanza have quiet base games and a buy RTP at or above base, and are bought more often than triggered at Feature Buy Slots. Starburst-style games with no bonus have nothing to buy. Book-style games with frequent free spins are usually cheaper to wait for. And a game with a moving price, Extra Chilli, rewards waiting by definition: the Feature Drop falls while you spin, and the round you buy at 30x is the same round you would have bought at 50x.

Where feature buy is not offered

Some markets do not permit the button, and in those markets Feature Buy Slots hides it and the games play by scatter only. Nothing else changes: the round, the RTP version and the demo are the same. Players in those markets can still use the ante bet where a game offers it.

Bonuses and wagering

Every promotion at Feature Buy Slots shows its wagering requirement, game weighting and stake cap while the bonus is active, and it also states whether feature buy is allowed with bonus funds. Many offers exclude it, because one purchase can exceed the stake cap by itself. Read that line before buying with a bonus balance. Free spin awards are tied to a named game at a fixed stake. Cashback, where offered, is calculated on net losses over the stated period with its own terms alongside.

Cashier

Balances are in EUR. Deposits by Visa, Mastercard, Skrill, Neteller, Trustly and paysafecard are credited on confirmation. Withdrawals return to cards, e-wallets or bank transfer after identity and address verification; e-wallets are released first, and paysafecard cannot receive payouts. A document uploaded at sign-up keeps the first withdrawal from being held.

Phone play

The lobby runs in any phone browser without an app. On a phone the buy button sits behind the menu icon or beside the spin button depending on the studio, and the price is always shown before a confirmation tap. Confirm the stake first, because the price is a multiple of it. Balance, bonus progress and limits follow the login between devices.

Safer play

Feature Buy Slots is for adults of legal gambling age. Deposit limits, loss limits, session reminders, time-outs and self-exclusion are in account settings; a lower limit applies at once. A buy compresses a hundred spins of variance into one tap, and the loss limit is the tool that fits it: set it in buys, not in spins. Independent help is available from Gamblers Anonymous (https://www.gamblersanonymous.org).

Support

The help centre at Feature Buy Slots explains each game's buy options, the base and buy RTP figures, and whether ante bet is available, with verification, withdrawals, limits and bonus terms on separate pages. The support team is reached by chat or contact form from the account menu; account matters are handled only with the verified holder.

Frequently asked questions

Is a feature buy the same round as a natural trigger?

Yes. The button starts the same round with the same rules and random outcomes. A few games sell enhanced rounds at higher prices, and say so.

Is buy RTP higher than base RTP?

Sometimes slightly, sometimes equal, occasionally lower. The game panel and the game page at Feature Buy Slots show both.

What is ante bet?

A 25% stake increase that raises the natural trigger rate; the buy button is disabled while it is on.

Can I buy a feature with bonus funds?

Only if the offer terms allow it. Many exclude it because one buy can exceed the stake cap.

Why is the buy button missing?

Feature buy is not permitted in your market. The game plays by scatter, and ante bet is available where offered.

Can I try buying in demo?

Yes. Demo mode includes the buy button on every game, at the same RTP version as real play.

What currency does Feature Buy Slots use?

EUR for accounts, deposits and withdrawals.

Buy ten rounds of Gates of Olympus in demo and note the spread. Decide a count, set a loss limit in buys, and play for real. Feature Buy Slots adds every new buy title with its price and both RTP figures on the day it ships.
