Bonus Buy Slots: Where Are They Legal or Restricted in 2026?

The same online slot can offer a Buy Bonus button at one casino and hide it at another. The difference may come from national regulations, a regional game version or an operator's decision. There is no single European rule covering every Bonus Buy feature.

Here is how five regulated markets approach these mechanics, based on official guidance available in October 2026.

What Is Bonus Buy in Online Slots?

Bonus Buy, also called Feature Buy or Buy Bonus, allows players to pay a set amount to enter a slot's bonus round directly rather than waiting for it to trigger during ordinary spins.

The purchase price is often expressed as a multiple of the base stake. A single purchase can therefore cost substantially more than an ordinary spin.

Buying a feature does not guarantee a profit. The result remains uncertain, and the payout may be lower than the purchase price.

Whether the option appears depends on the game's design, market-specific requirements and the version supplied by its developer. Different game providers may implement the mechanic differently.

Why Are Bonus Buy Features Restricted?

Regulators have raised concerns about the cost of certain features and the way gambling products encourage play.

In January 2020, the UK Gambling Commission reported that six operators offered feature purchases allowing customers to stake significant amounts to access bonus rounds. One game charged more than £3,000.

The Commission cited requirements concerning transparent game rules and features that encourage customers to increase stakes or chase losses.

Other authorities focus on different aspects. The Dutch regulator requires players to make conscious decisions before starting each game, while Germany imposes detailed requirements on virtual slots.

These approaches affect game design, but they do not create one universal European Bonus Buy prohibition.

Bonus Buy Rules by Country in 2026

The following comparison distinguishes confirmed regulations from enforcement decisions involving particular game features.

Country	Confirmed regulatory position	Practical implications
Great Britain	UKGC acted against feature buy-in products in 2020 under requirements 3A and 14A.	Bonus purchases must satisfy applicable game-design and stake requirements.
Netherlands	KSA prohibits automatic play and intervened against purchased sequences of automatic spins in 2022.	Buying multiple automatically executed spins is not equivalent to a separately initiated game.
Germany	Virtual slots have strict game-design rules. The standard €1 stake cap has conditional exceptions up to €5 since July 2026.	A purchased feature must comply with applicable stake and game-cycle requirements.
Malta	MGA imposes player-protection and game-information requirements.	An MGA licence does not automatically authorise a feature in another jurisdiction.
Sweden	Technical standards regulate game duration, interactive choices and queued actions.	The mechanics must comply with the applicable technical requirements.

Great Britain: Feature Buy Under UKGC Rules

The UKGC's 2020 intervention remains an important example. Six operators removed feature buy-in functionality after the regulator identified concerns about transparency and responsible game design.

The intervention concerned specific products. It should not be presented as a separate statutory ban on every feature carrying the Bonus Buy name.

British online slots also operate under age-based maximum stakes of £2 and £5, alongside other technical restrictions. How those requirements apply depends on the structure of the particular feature.

The distinction between a standard game cycle and additional purchases matters. Our guide to UK online slot rules explains the general limits.

Netherlands: Restrictions on Automatic Play

In April 2022, the Kansspelautoriteit reported an intervention involving online slots where customers could buy multiple spins that then played automatically.

The regulator explained that players must consciously decide whether to continue before each new game.

The operator removed the affected products after being warned of a possible penalty payment of up to €300,000.

This decision concerned purchased sequences of automatic spins. It does not establish that every mechanism for purchasing entry to a single bonus round is prohibited.

Germany: Stake Limits and Game Approval

German virtual slots are subject to detailed regulation under the Interstate Treaty on Gambling.

Requirements include a minimum five-second game duration, manual initiation of individual games and approval requirements for virtual slot titles.

The standard stake limit is €1 per game. However, the German regulator GGL confirms that conditional increases up to €5 became possible on 1 July 2026, subject to additional safeguards and eligibility requirements.

A Bonus Buy purchase cannot be assumed lawful merely because it is available in another market. Its mechanics must be assessed against the German requirements.

Malta and Sweden: Different Regulatory Approaches

The Malta Gaming Authority regulates operators through licensing, player-protection obligations and requirements governing gaming services.

A Malta licence does not automatically determine whether a particular feature may legally be offered to residents of Great Britain, Germany or another jurisdiction.

Sweden applies technical standards under SIFS 2022:3. These include a three-second minimum game round, reasonable time to consider interactive decisions and restrictions on queueing repeated player choices.

These are confirmed requirements affecting game design. They should not be described as a universal Swedish ban on Bonus Buy.

Are Bonus Buy Slots Legal at Offshore Casinos?

A casino operating under a foreign licence may offer features unavailable on locally regulated platforms. However, availability does not establish legality for residents of every country.

An operator must comply with the rules of the market where it provides gambling services. Some jurisdictions require local authorisation even when the operator already holds a foreign licence.

Players should check the relevant casino licence, the game's rules and the requirements of their jurisdiction.

A visible Bonus Buy button alone cannot establish compliance.

Does Bonus Buy Affect RTP or Risk?

Return to Player (RTP) describes the theoretical percentage of stakes returned over a large number of game rounds. It does not predict the outcome of an individual purchase.

Some games may publish different RTP figures for ordinary play and feature purchases. These figures must be checked in the specific game's official information rather than assumed.

Bonus Buy also changes the amount committed in one decision. Purchasing a feature for many times the ordinary stake exposes a larger amount of money to a single uncertain outcome.

That does not mean the feature guarantees better results.

Our guide to RTP and volatility explains these concepts in greater detail.

Why Is Bonus Buy Missing From Some Casino Games?

There are several possible explanations.

Reason	Explanation
Regulatory requirements	A game feature may be incompatible with rules applying in a particular market.
Regional game version	A developer may supply different configurations for different jurisdictions.
Operator settings	A casino may choose not to make a feature available.
Game design	The developer may exclude Bonus Buy from a particular release.

The absence of a purchase button is not proof of a legal ban. Similarly, its presence does not prove that a particular game complies with every local requirement.

The most useful information comes from the game's rules and the applicable regulator.

Conclusion

Bonus Buy availability depends on the mechanics of a game and the regulations of the market where it is offered. Great Britain, the Netherlands, Germany, Malta and Sweden apply different requirements, making a single European answer misleading.

Neither the presence nor the absence of a Buy Bonus button proves its legal status. Players should consider the game's official rules, the operator's licence and the requirements of their jurisdiction.

FAQ

Are Bonus Buy slots legal in the UK?

The UKGC intervened against specific feature buy-in products in 2020. Those products were removed by the six operators involved. Any Bonus Buy implementation must satisfy the applicable British gambling requirements.

Which countries restrict Bonus Buy slots?

Different markets restrict different mechanics. The UK has acted against specific feature purchases, the Netherlands prohibits automatic play, and Germany imposes detailed slot requirements. These measures should not be treated as identical bans.

Is Feature Buy the same as Bonus Buy?

The terms generally refer to paying to access a bonus feature directly. Developers may use different names and implement different mechanics, so the game's official rules remain important.

Why is Bonus Buy disabled in my casino?

Possible explanations include local regulation, a regional game version, operator settings or the developer's decision. The missing button alone does not reveal the reason.

Do Bonus Buy slots have a different RTP?

Some games may offer different theoretical RTP figures for their purchase modes. Check the developer's official game information. Buying a bonus does not guarantee a profit.

Can a licensed casino offer Bonus Buy in every country?

No. A casino licence does not automatically grant permission to offer every gambling product in every jurisdiction. Local licensing and game-design requirements still apply.
