The first time I watched someone spend 100 euros to skip straight to a bonus round on a slot game, I thought it was a novelty. Within a year, Bonus Buy had become one of the most controversial features in online gambling — and one of the clearest lines separating regulated markets from offshore ones. Spain’s DGOJ banned it. Most offshore casinos still offer it. The reasons on both sides tell you a lot about how different parts of the industry think about player risk.
How the Bonus Buy Feature Works in Slot Games
In a standard slot game, the bonus round — free spins, multipliers, special mechanics — triggers randomly during normal play. You might spin 200 times before it appears, or it might hit on the fifth spin. The randomness is the point: it creates anticipation, paces spending, and distributes bonus rounds across a player’s session in a way that the game’s mathematics can absorb.
Bonus Buy — also called Feature Buy or Feature Purchase — removes the waiting. For a fixed price, typically 50 to 100 times the base bet, you skip directly to the bonus round. Bet 1 euro per spin? The Bonus Buy costs 50 to 100 euros. The feature round plays out immediately, and whatever you win (or don’t) from those free spins is your result. No buildup, no anticipation gap, no gradual session pacing. It condenses what might be 20 minutes of play into a single high-stakes moment.
Providers like Pragmatic Play and others have built Bonus Buy into many of their popular titles. The feature is technically sound — the expected return of a purchased bonus round is calibrated to maintain the game’s overall RTP. But the pattern of play it creates is fundamentally different from standard slot sessions, and that difference is what regulators focused on.
There’s also a psychological dimension that the RTP calculation doesn’t capture. When a bonus round triggers naturally during play, it feels like a reward for patience — a surprise event that breaks the rhythm. When you buy the bonus round, you’ve made an active, deliberate spending decision. The cognitive framing shifts from «I got lucky» to «I invested.» That investment framing makes it harder to walk away from a losing Bonus Buy outcome, because the player perceives the money spent as a stake in a decision they made rather than a bet they placed. It’s a subtle difference, but it changes how losses feel and how players respond to them.
Why Spain’s DGOJ Banned Feature Purchases
I was at an industry conference when a DGOJ representative laid out the rationale, and it was more nuanced than the «nanny state» framing you see in gambling forums. The concern isn’t the bonus round itself — it’s the spending velocity.
A player using Bonus Buy can cycle through their bankroll dramatically faster than one playing at normal spin rates. At 1 euro per spin, a standard session might cost 200 to 300 euros per hour. With Bonus Buy at 100x the base bet, that same player can spend the same amount in minutes. The feature essentially removes the time buffer that separates impulse from action. For the roughly 14% of young online players aged 18 to 25 who show symptoms of gambling disorder, that acceleration is the difference between a manageable session and a catastrophic one.
Online casino generated 893 million euros in Spain’s regulated market in 2025, and the DGOJ’s position is that this revenue should come from sustainable play patterns rather than features that concentrate spending into short, high-intensity bursts. The ban isn’t unique to Spain — the UK’s UKGC has also restricted similar features — but Spain’s implementation is among the clearest: feature purchases are simply not permitted at DGOJ-licensed operators.
Where Bonus Buy Remains Available for Spanish Players
The ban applies to DGOJ-licensed operators. It does not — and cannot — apply to offshore casinos operating outside Spanish jurisdiction. This creates one of the more straightforward regulatory arbitrage situations in the market: a Spanish player who wants access to Bonus Buy slots will find them at virtually any offshore casino offering games from providers who build the feature into their titles.
The estimated volume of unregulated online gambling in Spain reached 231 million euros in 2024, and features like Bonus Buy are part of what drives players to seek out offshore alternatives. The irony is clear: a regulation designed to protect players from high-velocity spending pushes some players toward platforms with no protections at all. Licensed DGOJ operators have pointed this out repeatedly — every tightening of the legal market creates opportunities for the offshore sector.
The availability is essentially universal across the offshore market. Any casino operating under a Curaçao CGA licence, or under any non-European jurisdiction, can offer Bonus Buy without restriction. The feature is particularly prominent in newer slot releases, where providers increasingly design games with the Bonus Buy mechanic as a core selling point rather than an optional add-on. Some titles are explicitly marketed around their Bonus Buy pricing and bonus round volatility, targeting players who specifically seek out this style of play.
Whether that trade-off is acceptable depends on your perspective. From a public health standpoint, banning a feature that accelerates harmful gambling patterns is defensible even if some players circumvent it. From a market standpoint, every player who goes offshore to access Bonus Buy or crash games is a player who leaves all regulatory protections behind. There’s no clean answer, and anyone who tells you otherwise is selling something.
FAQ
What is the typical cost of a Bonus Buy relative to the base bet?
Bonus Buy prices are typically set between 50x and 100x the base bet. At a 1-euro base bet, the feature purchase costs 50 to 100 euros. Some games offer tiered Bonus Buy options with different price points corresponding to different bonus round types or volatility levels. The price is calibrated to maintain the game’s overall RTP across both standard and purchased bonus rounds.
Can Spanish players access Bonus Buy slots through VPN without legal consequences?
Using a VPN to access offshore casinos is technically possible but carries practical risks. Offshore operators who detect VPN usage may void winnings or freeze accounts under their terms of service. From the Spanish legal perspective, the DGOJ’s enforcement focuses on operators rather than individual players, but accessing blocked platforms bypasses protections designed for the player’s benefit — including dispute resolution, deposit limits, and self-exclusion enforcement.
