What Are Bonus Buy Slots?
Bonus buy slots give you the chance to jump straight into the best part of the game. Instead of spinning and waiting for free spins or bonus rounds to appear, you can pay to activate them instantly. Many of these slots include features like multipliers, re-triggers, expanding wilds, or special modes that can boost your chances of landing something worthwhile.
How Bonus Buy Features Work
With a bonus buy, you choose to pay a set fee to unlock the bonus round right away. The game charges a fixed multiple of your current stake and then activates the feature immediately. Depending on the slot you are playing, this could unlock free spins, building multipliers, special reels, or other high-potential extras.
How Do You Buy a Bonus in a Slot?
When you open a slot that includes a bonus buy option, you will see a button such as “Buy Feature,” “Bonus Buy,” or “Feature Buy.” Once you click it, the game shows you the price based on your current bet size. If you confirm the purchase, the cost is taken from your balance and the bonus round starts right away. It is a simple process, but it is always worth checking the price, volatility, and paytable before you buy so you know exactly what to expect.
How Much Do Bonus Buys Cost?
Most bonus buys fall between 50x and 200x your base bet, although many are priced in the 50x to 100x range. The exact amount always depends on the slot. For example, if you are wagering 1.00 per spin and the bonus buy costs 100x, you would pay 100.00 to trigger the feature instantly. The bonus round uses your chosen stake, and every win you collect is yours.
Why Do Some Bonus Buys Cost More Than Others?
Certain games offer a more expensive version of the feature that gives you better starting conditions. This can mean extra free spins, stronger multipliers, or a higher chance of reaching the slot’s most significant wins. These premium options cost more because they open the door to the slot’s maximum potential, such as larger multipliers, expanded reels, or even jackpot-style wins.
Slots featuring premium or super bonus buy options:
- San Quentin 2: Death Row (Nolimit City): 100x up to 2,500x
- Wanted Dead or a Wild (Hacksaw Gaming): 80x, 200x, 400x
- Buffalo Toro (ELK Studios): 10x to 500x
- Pirots (ELK Studios): 3x to 500x
- Money Jar 2 (Slotmill): 8x to 500x
- Big Bamboo (Push Gaming): 99x to 608x
What Slots Have The Cheapest Bonus Buys?
This guide highlights slot games with the most affordable bonus buy options. Low-cost bonuses, which are typically 10x to 70x the bet, allow players to access features like free spins and special wilds without the high expense of standard bonus buys (often 100x to 2,500x). Noteworthy low-cost options include Starburst Galaxy (10x), Punk Rocker 2 (15x), Nitropolis 2 (25x) and Zulu Gold (25x).
Does Buying the Bonus Change the RTP?
Buying the bonus can affect the Return to Player rate. Some slots offer a slightly higher RTP when the bonus is purchased rather than triggered naturally. Others maintain the RTP by adjusting the average win value within the feature. The quickest way to check is to look at the game’s information screen or paytable before you buy.
Games where the RTP increases when you buy the bonus:
- White Rabbit (Big Time Gaming): 97.24% to 97.77%
- Beast Mode (Relax Gaming): 96.3% to 97%
Does Buying the Bonus Make the Game More Volatile?
Yes. Bonus buys increase volatility, which means you will see bigger swings in your bankroll. You get immediate access to the most exciting part of the slot, but you also take on more risk. Even when you buy the feature, large wins do not appear often, and you may experience several low-value bonuses before you hit anything significant. Make sure you are comfortable with the financial and emotional ups and downs before choosing this style of play.
High volatility bonus buy slots include:
- Fire in the Hole xBomb (Nolimit City): Up to 60,000x
- San Quentin (Nolimit City): Up to 150,000x
- Money Train 2 (Relax Gaming): Up to 50,000x
- Dead or Alive 2 (NetEnt): Up to 111,111x
- Big Bamboo (Push Gaming): Up to 50,000x

Bonus Buy Slot FAQs
What are Bonus Buy slots?
Bonus Buy slots are games where you pay a fixed fee to jump straight into the bonus round instead of waiting for scatters to land in the base game. They are designed for players who prefer instant action rather than spinning for a long time hoping to trigger a feature.
How does the Bonus Buy feature work?
When a slot has a Bonus Buy feature, you will usually see a button such as “Bonus Buy,” “Buy Feature,” or similar. You pick your stake, click the button, and the game shows you the price. If you confirm, the amount is taken from your balance and the bonus round starts on the next spin without waiting for symbols to land.
How much does a Bonus Buy cost?
Most Bonus Buys cost somewhere between 50 times and 200 times your current bet size, although some games go lower or much higher. For example, if you bet 1.00 and the Bonus Buy price is 100x, you pay 100.00 to get straight into the bonus. The feature then plays at your chosen stake, and any winnings are yours.
Are Bonus Buy slots legal in the UK?
No. Bonus Buy features are not allowed in the UK. The UK Gambling Commission banned them in 2019 because they were considered too risky and could encourage players to overspend. If you are playing at a UK licensed casino, you should not see Bonus Buy buttons inside the game.
Are Bonus Buys worth it?
Bonus Buys can be worth it if you accept high risk and have the bankroll to handle big swings, but they are never a guaranteed way to profit. You are paying a premium to see the bonus round faster, and you can still end up with a poor result that does not cover what you paid to enter.
Do all slots have Bonus Buy features?
No. Only certain games from specific providers offer Bonus Buys. Studios like Nolimit City, Hacksaw Gaming, Relax Gaming, ELK Studios, and Big Time Gaming use Bonus Buys quite a lot, but many slots still rely on natural bonus triggers only.
Does using Bonus Buy affect RTP?
It depends on the game. Some slots slightly increase the RTP when you buy the bonus, others keep it the same as the base game. What always changes is the volatility. Bonus Buys usually make the game much swingier because you are going straight into the high risk part of the slot.
Can I use Bonus Buy with bonus funds or wagering requirements?
Usually you cannot. Most casinos block Bonus Buy features when you are playing with bonus money, or they state in the terms that using a Bonus Buy can void your bonus winnings. It is important to read the bonus rules before you try to buy a feature with promotional funds.
What types of Bonus Buy features exist?
There are several common versions of Bonus Buy features. Some games offer a simple instant buy, while others let you choose from different levels of bonus or even spin a wheel to decide which bonus you get. Super versions usually cost more but give you a stronger setup.
Should I avoid Bonus Buy if I have a small bankroll?
Yes, in most cases you should. Bonus Buys are expensive compared to normal spins and can wipe out a small balance very quickly if the features do not pay. If you play with a limited bankroll, it is usually safer to stick to regular spins and lower stakes instead of paying big upfront for a single high risk bonus.
