Although bonus buy slots are popular, there is a bit of controversy around them. When licensing casinos in the UK, the UK Gambling Commission ruled that the bonus buy encouraged faster spending, increasing the risk of gambling addiction. As a result, bonus buy slots are banned in the UK. However, if you choose feature buy slots on overseas sites, you have nothing to worry about — these features remain fully available, with no restrictions or upcoming changes announced.
How Bonus Buy Slots Work
Bonus buy slots, also known as feature buy slots at some online casinos, give you the option to pay for direct access to bonus rounds. These extras are typically free spins, multipliers, or other high-paying features. It means you don’t have to wait for them to trigger naturally, which can sometimes take quite a while.
The cost of bonus buy slots typically ranges from 50x to 200x your base bet, depending on the game and the value of the feature.
It’s not always easy to tell which online casinos offer standard slot games and which ones include the bonus buy feature. Bonus buy is typically an extra function built into regular slot software and doesn’t affect your ability to play the game as normal.
To find out if a title includes the bonus buy option, make sure to read the full game description before you deposit. Some platforms also make it easier by grouping bonus buy slots into a dedicated category on their site.

Top 5 Bonus Buy Slots Free Play Options
Due to the growing demand for this feature, many new slots are being launched, which can make it hard to choose the best bonus buy slots for your gaming preferences.
Therefore, our expert team has selected some of the best bonus buy slots you can play today.
Online Slot Money Train 2
This creation of Relax Gaming takes you to a post-apocalyptic world ruled by extremely powerful people, so you’ll have to really fight for your winnings. The steampunk style and extraordinary characters make it feel incredibly realistic.
There are five reels in four rows and 40 paylines. It also has an RTP of 98% and high volatility, which gives you a higher chance of winning big.
Here’s how the bonus buy feature works here:
- Re-spins are activated when two scatters appear on the reels. After every unsuccessful move, the multiplier increases by +1 until a winning combination comes out.
- Free spins become available after three scatter symbols pop up. The spins then start, and you have four attempts at the multipliers. All actions are summed up and then multiplied by the bet. The game continues until you are out of moves.
Gems Bonanza
Pragmatic Play is based on gemstones and uses clusters to make the gameplay exciting. With the bonus buy, there’s a maximum win of 100,000 coins for the highest-paying symbol.
With the clusters and RTP of 96.51%, it’s risky but can provide big rewards if you’re lucky, especially if you choose to pay for the bonus round. Each reel has an extra; the highlighted stone will enter the winning chain if activated. The different colours mean a different bonus; for example, blue explodes everything around it and red expands the gem to several cells.
After a sufficient number of combinations have accumulated on the counter, another bonus round starts.
Stack ‘Em
This activity by Hacksaw Gaming was released in May 2021 and contains lots of multipliers and bonus round potential.
It is set in the countryside with calming graphics, and you’ll see the main character, Canny the Can, and his friend, Mouse, watching as you play.
The bonus round is represented by wild and scatter symbols, which appear in random order and provide a decent profit. In addition, each successful spin in Stack ‘Em is rewarded with a re-spin, the winning combination stays on the reels, and the rest of the symbols disappear, making space for new sticks. The multiplier grows if the move is again a winning one.
What’s good about this game, in particular, is that there’s no need to stay stuck on specific lines, which gives you a better chance of winning the main prize.
Starburst XXXtreme
Gems are a popular theme in bonus buy slots, so NetEnt integrated it into some of their existing games.
This slot has the classic 5×3 reels and an inviting bonus buy option to increase your chances of a solid jackpot. You’ll also get a maximum multiplier of x150, which appears with the expanding wild sign. This means that if you’re lucky, your bet will increase 200,000 times!
When paying for the buy bonus round, remember:
- There’s one guaranteed wild for each spin when playing at 10x the bet amount.
- Two Jokers in each spin are worth 95x the bet amount.
As with any game, bonus buy slots come with risk — you could wait for the extra to trigger on its own, but plenty of players choose to pay for the joy of instant action.
Chaos Crew
The bonus buy slot has a gothic punk style that makes it stand out compared to other titles. You’ll find hand-drawn symbols in lurid shades on the 5×5 grid and combinations that start to appear from the far left reel. It’s up to you to collect at least three identical items.
The bonus buy option in this game is additional spins together with the wilds that can increase the final amount by 10,000 times. Having placed the maximum bet, the player can pick up 1,000,000 coins.
At an above-average RTP of 96.3%, this is an attractive slot which encourages people to play bonus buy slots to get bigger payouts.
Here are the two extra features you can use:
-
Wilds: The wild symbol can offer multipliers from x2 to x5 when multiple icons appear in the chain.
-
Free spins: These are activated after three scatters land and give the player three spins. As long as the multipliers stick to the reels, the game continues. When you’re out of spins, all the dropped multipliers are added together and multiplied by the bet.
Summary
There are plenty of online casinos that feature bonus buy games in 2025, but the choice of whether to get involved in such is totally up to you.
Bonus buy slots can be a great way to speed up the gaming process and avoid having to wait around for extras to appear naturally. It makes things more fascinating and can give players even more chances to win big.
However, although free slot games with free spins sound very alluring, it’s worth noting that uncontrolled play leads to a quick waste of your bankroll and can even lead to gambling addiction in some cases. To avoid wasting money, players can take advantage of the demo mode, where they can test out the buy bonus before spending their own money.
But don’t let that put you off; playing bonus buy slots can be pretty profitable. Choose a reasonable price within 100 times the size of the bet if you want your best chance of winning big.
