A bonus buy, also called a feature buy, lets you pay a multiple of your stake to jump straight into a slot's feature round. No waiting through two hundred base spins for a trigger that may not come.
It is a genuinely useful mechanic and it does not do what most players think. Here is the arithmetic.
Buy Costs and Published Returns
Prices are quoted as a multiple of your current stake, and the spread is wide.
Title
Buy cost
Published return on the buy
Fire in the Hole (Nolimit City)
75x to 400x by tier
Varies by configuration
Mental (Nolimit City)
500x
96.69%
San Quentin (Nolimit City)
100x to 2000x by tier
Up to 98.07%
Typical low to mid volatility
50x to 100x
Check the panel
Typical high volatility
100x to 200x
Check the panel
Two things in that table matter more than the numbers.
First, buy tiers are certified separately. San Quentin's lowest and highest buys are different products with different published returns, and the mid-tier is sometimes the mathematically stronger pick. Nothing about the interface tells you which.
Second, the real cost scales with your stake and people forget this. At a £5 spin, a 100x buy is £500 in a single click. That is not a slot spin; it is a substantial standalone wager, and it should be sized as one.
The Return on a Buy Is a Separate Figure
This is the part worth understanding properly, because coverage of it is contradictory.
The bought feature's return is calculated and certified separately from the base game. Sometimes it sits slightly above, with figures around 96.7% to 97.0% against 96.5% for natural play, on the reasoning that you skip base-game variance. Sometimes it sits below.
Which means there is no general rule, and anyone telling you bonus buys have better or worse odds is generalising from one title. The only dependable move is reading the figure for the specific tier you are about to buy, in that game's information panel, at that platform.
Speed Is What a Buy Changes
Here is the honest core, and it disappoints people.
House edge is unchanged. Developers price a buy close to the theoretical value of the round it unlocks, so paying 100x for a feature that averages slightly less than 100x back is the same proposition as grinding to it naturally. The edge applies either way.
What changes is speed. A buy compresses a hundred spins of exposure into one decision, which means the edge is applied to your bankroll far faster. The mechanic does not improve your odds; it accelerates the rate at which the odds do their work.
And the buy guarantees the round, not the result. A 100x purchase on a high-volatility title frequently returns 30x or 50x, because the feature round has its own variance. You are buying entry, not an outcome.
Where You Can and Cannot Use It
The regulatory picture splits the market cleanly.
A UKGC ban applies to operators holding its licence: the Gambling Commission removed the mechanic for operators holding its licence, on the reasoning that compressing high spend into a single-click decision drives problem gambling.
Providers respond by disabling the buy button for that market while leaving the base game fully intact, so the titles remain playable and the shortcut does not.
Offshore-licensed platforms are unaffected, which is why bonus buy remains standard across crypto casinos. That is a regulatory difference, not a quality one, and it is worth knowing which side of it you are on.
One practical trap regardless of jurisdiction: many operators exclude bonus buys from wagering contribution entirely, or count them at a reduced rate. Buying a feature while clearing a bonus can therefore cost you the purchase and advance you nothing, and terms quality varies between platforms considerably.
Four Platforms Carrying Buy-Enabled Titles
Availability follows the studio roster, since the mechanic is built by the game maker and not the casino.
Dexsport carries Pragmatic Play, Nolimit City, Hacksaw and BGaming among roughly twenty slot studios, and all four produce buy-enabled titles. Because it holds an Anjouan licence instead of a UK one, the buy button is not stripped from the versions it runs. Its demo mode is genuinely useful here specifically, since it lets you open a title and read each tier's published return before committing several hundred times your stake. It is non-custodial, with a licence lighter than Curacao or Malta.
Stake and BC.Game both carry extensive Nolimit City and Pragmatic catalogues alongside their own 99% originals, which are a different and generally better-priced proposition than any bought feature.
Vave provides third-party coverage including buy-enabled titles, with no originals suite to compare against. Dexsport sits in the same category, licensing everything, which is why its demo access matters more there than at a platform with 99% house games to fall back on.
Which studios a platform carries determines which buys you can reach, and game supply shapes a lobby more than any platform-level feature.
Buying Sensibly
Three habits if you use the mechanic at all.
-
Check the tier's published return before clicking, since tiers differ and the lowest-priced is not always the strongest value. Dexsport's demo mode lets you do this without spending anything
-
Size the buy as a standalone wager, not as a spin, because at 100x it is one
-
Decide in advance how many you will buy, because the failure mode is purchasing a fourth to recover the first three
Confirm what is legal where you live, keep stakes within a set budget, and play only if you are of legal age, since KYC or AML checks may apply.
Responsible gambling is the reason this mechanic is restricted in some markets, and the regulators' reasoning is worth taking seriously even where it remains available: a large single-click spend removes every natural pause a base game provides.
