Bonus Buy Slots: Does Buying the Feature Change Your Odds?
Bonus buys don't change your odds per dollar, they change the speed. Feature buy RTP, cost-per-hour maths and our data on 424 Hotdog slots.
In this article
A bonus buy lets you skip the base game and pay a fixed price, often around 100 times your bet, to start the free spins round straight away. Buying the feature doesn’t meaningfully change your odds per dollar staked. It changes how fast you stake, and how wildly your balance swings. Below we show what that costs per hour at 96.5% RTP, and what 424 slots in our Hotdog Gaming catalogue data reveal about games with a buy button. We also correct a common myth about the UK “ban”.
What is a bonus buy (feature buy)?
Most slots hide their biggest payouts inside a bonus round. Normally you reach it by landing scatter symbols, which might take a few hundred spins. A bonus buy, also called a feature buy, puts a button on the screen that skips the wait. You pay a set price, the reels spin once, and the free spins round starts.
What the button guarantees is entry, not a win. The bonus round still runs on the same random number generator. It can pay 300x your bet or 8x.
It also doesn’t make a game “due”. Each round is independent, which we explain in why a slot is never due to hit.
Takeaway: you are buying a ticket into the bonus, not a better chance of winning it.
How is the bonus buy price set?
The studio works out the average return of its bonus round, then prices the button so the bought feature still returns slightly less than it costs. The price is shown as a multiple of your current bet, so it scales with your stake. A 100x buy costs $100 at a $1 bet and $1,000 at a $10 bet.
That scaling is how prices get large fast. When the UK Gambling Commission looked at feature buy-ins in January 2020, it found one game charging more than £3,000 to enter a bonus feature.
Takeaway: the buy price is not a discount. It is the studio’s estimate of what the bonus is worth, plus a margin for the house.
Feature buy RTP vs base-game RTP
RTP (return to player) is the long-run share of stakes a game pays back. Some studios publish one RTP for normal play and a separate figure for the bought feature. The two can be the same, a little higher or a little lower. A slightly higher buy RTP sounds like a bargain, but on the much bigger sums you wager it rarely means you lose less per hour (see the maths below).
Here’s how to check a specific game before you press anything:
- Open the game’s help or paytable screen (the “i” or menu icon).
- Find the RTP line. Look for a second figure labelled feature buy, bonus buy or buy feature.
- If there is only one figure, you don’t know whether the bought feature differs. Don’t assume it’s better.
- Note the buy price as a multiple of your bet, then multiply by your stake to see the real cash cost.
- Run the numbers in our RTP calculator before you decide.
Takeaway: a separate feature buy RTP is a detail. The size and speed of the stake matter far more.
What our data shows: bonus buy slots in the Hotdog catalogue
In our data (Hotdog Gaming catalogue, synced 20 Oct 2026), 424 of the 443 games are slots. Each record has a “buy” field, the game’s listed RTP, a volatility rating from 1 to 5 and a max-win multiplier.
One honest caveat first. Only 3 slots say “No”. Another 204 leave the field blank (N/A). Blank does not prove a game has no buy option, so we report it as “not listed”. The RTP below is the game’s single listed RTP. Our data does not show a separate RTP for the bought feature.
| Hotdog slots, by buy field | Feature buy: Yes | Not listed (N/A) | Feature buy: No |
|---|---|---|---|
| Number of slots | 217 | 204 | 3 |
| Average listed RTP | 96.70% | 96.18% | 95.90% |
| Median listed RTP | 96.76% | 96.69% | 96.50% |
| Listed RTP 97% or higher | 90 (41%) | 32 (16%) | 1 |
| Listed RTP below 96% | 18 (8%) | 47 (23%) | 1 |
| Volatility 4 or 5 (of 5) | 92 (42%) | 58 (28%) | 1 |
| Median max win | 5,000x | 2,992x | 1,025x |
| Max win 10,000x or more | 73 of 212 (34%) | 20 of 194 (10%) | 1 |
| Biggest max win | 100,000x | 25,000x | 13,500x |
The medians are almost identical: 96.76% vs 96.69%. The averages differ more because the not-listed group contains more games below 96%. So a buy button does not signal a better game. It tends to sit on games built for big swings.
Takeaway: in our data, slots with a feature buy have similar median RTP but much more often carry high volatility and 10,000x+ caps.
Volatility and max-win caps
Volatility 3 is the most common rating in both groups. The difference is at the top end. Among buy-listed slots, 42% are rated 4 or 5, against 28% of not-listed slots. Max-win caps show the same pattern: 34% of buy-listed slots can pay 10,000x or more, versus 10% of the rest.
High volatility means long dry spells broken by rare big hits. Our RTP vs volatility guide explains why two games with the same RTP can feel completely different.
Takeaway: the buy button and high volatility usually come as a pair.
How many Top 30 slots have a buy button?
We also checked each market’s Top 30 Hotdog games by September 2026 turnover.
| Top 30 list | Feature buy: Yes | Not listed | No |
|---|---|---|---|
| All markets | 22 | 6 | 2 |
| Thailand (THB) | 24 | 5 | 1 |
| Malaysia (MYR) | 22 | 8 | 0 |
| Indonesia (IDR) | 19 | 11 | 0 |
| India (INR) | 23 | 4 | 3 |
| Philippines (PHP) | 27 | 3 | 0 |
| Total | 137 of 180 (76%) | 37 | 6 |
Popular titles with a listed buy include Pinata Ways (listed RTP 97.33%, volatility 4) and Golden Ganesha (97.53%, volatility 3). Turnover rankings measure money staked, not player wins. The full lists are on our Top slots page.
Takeaway: about three in four of the top-turnover Hotdog games in these markets list a buy button, so you will meet this choice often.
Worked example: one 100x buy vs 100 spins
This is pure maths, not a test we ran. Assume a $1 bet, a 96.5% RTP for both the base game and the bought feature, and a 100x buy price.
| Illustration by HotStakes | 100 base spins at $1 | 1 bonus buy at 100x |
|---|---|---|
| Money staked | $100 | $100 |
| Expected loss (3.5%) | $3.50 | $3.50 |
| Rough time taken | about 10 minutes | about 1.5 minutes |
| Assumed rounds per hour | 600 spins | 40 buys |
| Money staked per hour | $600 | $4,000 |
| Expected loss per hour | $21 | $140 |
| If buy RTP were 96.0% instead | n/a | $160 per hour |
Per dollar, nothing changed. Per hour, the expected loss is about 6.7 times bigger. That’s the hidden cost of a feature buy.
The assumptions in plain terms:
- A spin every 6 seconds, including pauses. The UK already bans slot spins faster than 2.5 seconds, so many players go faster than this.
- One buy plus its bonus round every 90 seconds.
- Expected loss = money staked × (100% − RTP). Over one session your real result will land far from this average, in either direction.
The house edge always comes off the money staked, which is the point of our why the house always wins explainer.
Takeaway: RTP is a rate. Buying bonuses multiplies the amount it is charged on.
Variance: why the same RTP feels very different
With a $500 budget, you get 500 spins at $1, or 5 bonus buys at $100.
Five buys is a tiny sample. A bonus round’s average might be close to 96.5x, but that average is propped up by rare huge rounds. Many single rounds pay well under the price. So five buys can easily leave you with a fraction of your $500 in under 10 minutes. Five hundred spins spread the same expected $17.50 loss over nearly an hour.
Bonus rounds also play winning animations even when the total is less than you paid, a pattern known as “losses disguised as wins”.
Takeaway: the same RTP with fewer, bigger bets means a wider spread of outcomes and a faster route to zero.
Where bonus buys are restricted
A widely repeated claim says the UK banned feature buy in its 2021 slot design rules. The record is more specific.
- United Kingdom. On 17 January 2020, the Gambling Commission warned operators after finding six offering feature buy-ins. It cited its technical standards, including RTS 14A: products must not encourage players to chase losses or raise stakes. All six removed the feature. Law firm CMS described it as a call to remove the functionality. The separate February 2021 package banned autoplay and spins under 2.5 seconds from 31 October 2021. That release doesn’t name feature buy.
- Netherlands. Industry reports, including a February 2024 Next.io article, say the Dutch regulator KSA also bars bonus buys. We could not find the KSA rule text, so treat this as reported.
- Sweden. We found no Swedish ban. A 2024 poll commissioned by game studio Play’n GO found 55% of Swedish slot players wanted one, as Next.io reported.
- Germany. The 2021 State Treaty caps virtual slot stakes at €1 per game and requires games to last at least five seconds on average (§ 22a GlüStV 2021). We found no clause naming feature buy, but a 100x buy would mean far more than €1 on a single game.
Takeaway: UK regulators pushed feature buy off licensed sites in 2020 for encouraging bigger stakes. In the Asian market Top 30 lists in our data, the button is still everywhere.
Is bonus buy worth it? An honest checklist
Bonus buys don’t improve your expected result, so “worth it” comes down to cost. Ask yourself these before you press the button:
- What is the price in cash at my current bet, not as a multiple?
- How many buys does my whole session budget cover? If the answer is under 10, one bad run ends the session.
- Does the help screen show a separate feature buy RTP? If not, I don’t know what I’m buying.
- Am I buying to win back a loss? That’s chasing, the behaviour the UK regulator flagged.
- Am I playing with bonus money? Check the terms first. Our wagering requirements guide explains why.
If you notice you’re buying bonus after bonus to chase losses, take a break. Our guide to blocking gambling covers apps, bank blocks and self-exclusion.
Takeaway: for most players, normal spins at a smaller stake give the same odds with far less damage per hour.
FAQ
Does a bonus buy increase your chances of winning?
No, not per dollar staked. It guarantees entry to the bonus round, but the price is set so the bought feature returns less than it costs over time. If its RTP matches the base game, your expected loss per dollar is the same. You simply stake much more, much faster.
What is feature buy RTP?
It’s the long-run return of the bought bonus, which some studios list separately in the game’s help screen. It can be equal to, slightly above or slightly below the base RTP. Our Hotdog catalogue data holds one listed RTP per game, not the bought-feature figure.
How much does a bonus buy usually cost?
The price is shown as a multiple of your bet, so it rises with your stake. At 100x, it’s $100 on a $1 bet. The UK Gambling Commission found one game charging more than £3,000 for a single bonus feature in 2020.
Are bonus buy slots banned in the UK?
UK-licensed sites were told to stop offering them. In January 2020, the Gambling Commission warned operators that feature buy-ins risked breaching its standards, and all six it contacted removed them. The 2021 game design rules banned autoplay and fast spins but don’t name feature buy.
How many Hotdog slots have a feature buy?
In our data (Hotdog Gaming catalogue, synced 20 Oct 2026), 217 of 424 slots list a feature buy, 3 say no and 204 leave the field blank. Across six Top 30 lists, 137 of 180 entries list a buy.
