Bonus buy - sometimes called feature buy - is one of the most divisive mechanics in modern slots. It lets you pay an upfront price to skip the base game and trigger the bonus round immediately. For UK players, it is worth understanding properly, because it is one of the things you get at non-Gamstop sites that UKGC-licensed casinos no longer offer.

How bonus buy works

Most feature-driven slots have a base game and a bonus round - usually free spins, where the big win potential lives. Normally you reach the bonus by landing scatter symbols during base play, which can take a long time.

Bonus buy removes the wait. A "buy feature" button sits on the game interface with a price attached, typically expressed as a multiple of your stake - commonly between 80x and 200x, though some titles go higher. Pay it, and the game drops you straight into the bonus round.

The studios that built their reputation partly on this mechanic - Nolimit City, Hacksaw Gaming, Pragmatic Play, Big Time Gaming - put it front and centre on many of their high-variance titles. On a Nolimit City release like Fire in the Hole or a Hacksaw title like Wanted Dead or a Wild, the buy is often the headline way the game is marketed.

What it costs

This is where players need to be clear-eyed. A bonus buy is not a discount or a shortcut to value - it is a large, concentrated bet.

• The price is steep. At 100x your stake, a £1 base bet means a £100 bonus buy. That is your whole session budget in one click for some players.
• The RTP is similar, not better. Bonus-buy RTP is usually close to the base-game RTP - sometimes marginally higher, sometimes lower. You are not buying better odds. You are buying a single high-variance event.
• The variance is brutal. You are staking a large amount on one bonus round. It can deliver a big multiplier. It can also return a fraction of what you paid. Both are common outcomes.

Think of a bonus buy as compressing a long, high-variance session into one expensive moment. The maths is broadly the same; the volatility is concentrated.

A worked example

Say a slot offers a 100x bonus buy. At a £0.20 base stake, that is a £20 buy. At a £1 base stake, it is a £100 buy. The bonus round itself might return anything from a fraction of the cost to a large multiple of it, but the most common outcomes cluster well below the headline max win. If you would not be comfortable losing the buy price on a single spin, the stake is too high - and that is the honest test to apply every time.

The appeal

Despite the cost, the appeal is real:

1. Time. You skip potentially hundreds of base spins to reach the part of the game you actually want to play.
2. The experience. High-variance bonus rounds are the most exciting part of these slots. Bonus buy is a direct ticket to them.
3. Control over when. Instead of waiting on a random trigger, you decide when the bonus happens.

For a player who understands the cost and has the budget, that is a legitimate trade. The danger is the player who treats it as a fast route to a win - because it is not.

Why it is restricted in some markets

The UK Gambling Commission banned slot bonus-buy features for UKGC-licensed sites, citing the risk of accelerated losses and the way the mechanic can intensify play. Several other regulators have taken similar steps.

Non-Gamstop sites operate under offshore licences, so bonus buy is generally still available. That is a genuine difference - but it cuts both ways. It is a feature some players value, and it is also one regulators removed specifically because of how fast it can drain a balance. Both things are true.

Playing bonus buy sensibly

If you do use the feature:

• Set the buy price against your whole budget. If one buy is most of your bankroll, the stake is too high - lower your base bet.
• Treat each buy as a complete bet that can lose entirely. Many do.
• Do not chain buys to chase a result. That is how a session goes from £50 to £300 fast.
• Check the bonus-buy RTP in the game info panel - it is listed separately from the base RTP.
• Decide a buy limit before you start. For example, no more than three buys in a session, full stop.

Where to find bonus buy at non-Gamstop sites

Bonus buy availability follows the high-variance studios. Among the operators we cover, Rolletto's roughly 24-provider library and Velobet's slots-heavy lobby both carry deep Nolimit City, Hacksaw and Pragmatic ranges where the feature is common. Zizobet's 8,000-title library stocks the full set, and Cosmobet's 7,500-game lobby carries the headline bonus-buy titles too.

Our slots shortlist notes which operators carry the bonus-buy studios, our bonuses shortlist covers welcome offers, and the methodology page explains how we assess feature availability and RTP transparency.

Frequently asked questions

Does buying the bonus give better odds than triggering it naturally?

No. The bonus-buy RTP is usually close to the base-game RTP. You are paying for instant access and a concentrated bet, not improved odds.

Why can I not buy bonuses at UK-licensed casinos anymore?

The UK Gambling Commission banned the feature for UKGC-licensed operators over concerns it accelerates losses and intensifies play. Offshore non-Gamstop sites are not bound by that rule.

Is bonus buy worth it for a small budget?

Generally no. If the buy price is a large share of your total budget, one unlucky buy ends your session. Smaller budgets are better served by low base-stake play across more spins.

The bottom line

Bonus buy is a powerful, exciting feature - and an expensive, high-variance one. It does not improve your odds; it concentrates them. Used with a clear head and a real budget, it is a legitimate way to play. Used to chase a win, it is one of the fastest ways to lose more than you planned.
