What's the average cost to buy a bonus in slot games?

Most bonus buy slots charge between 80x to 100x your bet for standard features. Budget options start around 50x, while premium features can reach 500x or even 1000x. The cost typically reflects the feature's volatility and maximum win potential. Higher-priced bonuses often include enhanced features like guaranteed multipliers or extra spins.

Can I test bonus buy features without spending money?

Yes, all bonus buy slots on Slottomat offer free demo versions with unlimited virtual credits. You can purchase bonuses repeatedly to understand payout patterns, test different bet sizes, and compare feature values across games. Demo play provides identical mechanics to real-money versions, making it perfect for risk-free learning.

Do bonus buy slots have better odds than regular slots?

Bonus buy slots don't inherently offer better odds. The overall RTP remains similar, but buying bonuses typically has a slightly lower RTP than achieving them naturally. The advantage is time efficiency and guaranteed access to high-volatility features where big wins occur, rather than improved mathematical odds.

Which providers offer the best bonus buy features?

Leading providers for innovative bonus buy mechanics include Pragmatic Play (100x standard buys), Nolimit City (multiple buy options), Push Gaming (Bonus Buy Revolution series), and Hacksaw Gaming (varied cost tiers). Each provider brings unique twists like multi-level purchases, mystery buys, or enhanced feature options.

Why are bonus buy slots banned in some countries?

Some jurisdictions like the UK banned bonus buy features in 2019 as a responsible gambling measure. Regulators worried the instant gratification and high costs could encourage problem gambling behavior. The feature remains legal in many other regulated markets including various US states, Canada, and most of Europe.

What's the difference between bonus buy and feature drop?

Bonus buy requires an upfront payment (like 100x bet) for instant access. Feature drop is a different mechanic where you collect tokens during regular play that reduce the bonus cost over time. Some games combine both, letting you buy outright or accumulate progress toward a cheaper purchase price.

What Are Bonus Buy Slots?

Bonus buy slots are online slot games that include an optional feature allowing players to pay a predetermined multiplier of their bet to instantly trigger the game's bonus round. Instead of spinning the reels repeatedly in the hope of landing the required scatter symbols, you can access the free spins , pick-me games, or other special features directly. This mechanic caters to players who prefer the high-volatility , feature-packed excitement of bonus rounds without the waiting time. It's crucial to understand that when playing bonus buy slots in demo mode, you're using virtual credits to learn how the buy feature works, which provides a safe and educational experience.

How Does the Bonus Buy Feature Work?

Buy features work the same across most games. Here's the simple breakdown:

What does "bonus buy" mean in slots?

In slots, "bonus buy" refers to an optional feature where a player can pay an extra amount, typically a multiple of their current bet, to instantly trigger the game's bonus round (like free spins) instead of waiting for it to land randomly in the base game.

Is it worth it to buy a bonus on a slot machine?

Whether it's "worth it" depends on your goals and bankroll. Buying a bonus increases volatility and cost but guarantees feature access. It's best suited for players who understand the risk and are primarily chasing big bonus round wins. We strongly recommend testing the feature extensively in free demo play, like on Slottomat, to understand its dynamics before committing real funds.

Do you win more with bonus buy?

Not necessarily. The bonus buy feature gives you more frequent access to the opportunity for bigger wins that the bonus round provides, but each individual outcome is still random. Over a long period, the game's RTP governs the return, and the buy feature often has a marginally lower RTP than the base game. You experience the bonus round's payout distribution more quickly, which can mean more frequent large wins but also more frequent losses of the buy-in cost.

What is the difference between bonus buy and free spins?

Free spins are a type of bonus round, typically awarded by landing scatter symbols or purchased via the bonus buy. The key difference is access: "Free spins" usually refer to the round itself, which can be triggered for free through gameplay. "Bonus buy" is the paid mechanism to instantly trigger that free spins round (or any other bonus feature) without waiting.

Are bonus buy slots legal?

Yes, bonus buy slots are legal and offered by licensed online casinos in many regulated markets worldwide, including various US states, Canada, and Europe. However, some specific jurisdictions (like Great Britain) have banned the feature as a responsible gambling measure. Always check the game availability and rules based on your location.

Bonus Buy Slots — Play Every Feature-Buy Demo Free

Last updated: 2026-04-20

Bonus buy slots let you skip the base game and trigger the feature round directly for a fixed cost. On Slottomat, every bonus buy slots demo runs on play-money credits — no deposit, no sign-up, no download.

Bonus Buy Slots Explained

A buy feature (sometimes labelled Feature Buy, Bonus Buy, or Buy Free Spins) is a button on the bet panel that triggers the game's bonus round immediately in exchange for a fixed stake multiplier. Typical costs run from 50x stake for budget slots to 500x+ for high-ceiling releases. The base game is bypassed entirely — the RNG still decides the outcome, but you no longer wait for a natural scatter trigger.

Feature-buy buttons are regulator-dependent. They are disabled in the UK and certain other jurisdictions under responsible-gambling rules; they remain available in many other regulated markets. Always check the in-game paytable for the exact cost and RTP applied to your chosen site.

Best Bonus Buy Slots to Try Free

Curated list of bonus buy slots with live demos on Slottomat:

Sweet Bonanza — Pragmatic Play tumble slot; 100x stake buys 10 free spins with multiplier symbols.
Gates of Olympus — same Pragmatic engine, Zeus theme, 100x bonus-buy cost.
Mental — Nolimit City's extreme-variance release with multi-tier feature buys.
Bonus Joker II — budget-friendly buy at around 50x for a classic-fruit feature round.
9 Coins Grand Gold Edition — hold-and-spin jackpot slot with buy access to the main feature.
Liger Loot — direct buy into the free spins round with stacked Liger wilds.
40 Hot Twist — classic-fruit slot with a modern feature-buy option.
Sweet Bakery — sticky-win respins via a purchasable feature.

Tiki Tumble Bonus Buy — feature-buy tumble slot with Polynesian theme.

Buy Costs & RTP

Typical cost tiers on popular releases:

Budget (50x–80x stake): Bonus Joker II, Extra Juicy-style classics — smaller variance, more frequent buys.
Mid (80x–120x): Sweet Bonanza, Gates of Olympus, most Pragmatic Play titles — a market standard for tumble-reel free spins.
Premium (150x–500x): Nolimit City releases and other max-win-focused slots — higher variance, higher top-win potential.
Extreme (500x+ or multi-tier): Mental and select Nolimit City / Hacksaw titles — the feature-buy cost reflects the game's exceptional max-win ceiling.

RTP applied to bonus-buy transactions is typically 0.5–1% lower than the base-game RTP. A slot with a 96.5% base RTP may return 95.5–96% when triggered via the buy button. Transparent studios (Nolimit City, Push Gaming) display both figures in the paytable; less-transparent releases may bury the figure in terms-and-conditions screens.

How to Play Bonus Buy Slots

Open a demo on this page: every linked game above loads play-money credits instantly.
Choose your base bet: the buy cost is a multiplier of your stake, so $1 bet on a 100x-cost slot means a $100 buy.
Locate the Buy button: usually beside the spin button or on a dedicated feature-buy menu for multi-tier games.
Confirm the purchase: the slot drops straight into the bonus round — no base-game wait.
Read the paytable: both base-game RTP and bonus-buy RTP are listed; confirm before ever using real money.

Strategy & Bankroll

Buy features concentrate your spend into fewer, larger events. That makes volatility feel sharper. Practical guidance:

Use demo mode to trigger at least 20 bonus rounds on a given slot before judging its distribution — a single round will mislead either way.
Treat a buy-only session as a high-variance bankroll exercise — budget for 10 purchases at your chosen stake and accept that one good hit or one cold stretch skews the picture.
Do not chase losses by escalating buy tier mid-session. If a 100x buy underperforms, a 200x buy does not recover it.
Check whether feature-buy is disabled in your jurisdiction before depositing at any operator; UK-licensed sites cannot offer it.

Final Word

Bonus buy slots suit players who want to study feature rounds in volume, test high-volatility slots without long dry stretches, and make informed comparisons across studios. Demo mode on Slottomat gives you that practice at zero cost. Start with a low-tier buy on a Pragmatic Play tumble slot, move to premium Nolimit City releases once the mechanic feels familiar.
