How does the Buy a Bonus Feature (Feature Buy) work?

The Buy a Bonus Feature, gives the players the option to activate the free spins. Simply by buying these. This way, you don’t have to wrestle your way through the main game. Instead, you go straight for the kill!

Often this feature is also called the:

  • Buy Feature
  • Feature Drop
  • Bonus Feature Buy
  • Buy Free Spins Feature
  • Bonus Buy
  • Buy Pass

Lots of names, for the same feature: you buy the free spins.

Yeah, the “free” spins should perhaps have been called the “paid” spins…

The advantages are clear: no need to wait. The downside? There’s a price to pay.

But sometimes, you have to take that for granted. And who knows, you might get a massive payout! And you’re guaranteed to get lots of action.

top 10 slots bonus buy feature

No. 1: Money Train – Relax Gaming

Year: 2019
RTP main game: 96.20%
RTP bonus feature: 98.0%
Variance (volatility): high
Max win: 20.000x the bet
Cost Bonus Buy: 80x the bet

Money Train is a slot with tremendous contradictions. The main game is incredibly dull, but the free spins are fan-tas-tic!

What great news, that these can be purchased right away. This way, you skip the boring main game. And the RTP? That’s an excellent 98%.

The theme is about robbing a train in the Wild West—a train wagon with many cash prizes. But thanks to the several boosters, there are many ways to get filthy rich here.

Exciting till the very end and who knows, you might land a sky-high win. A warning’s in place here. It’s incredibly addictive!

No 2: White Rabbit – Big Time Gaming

Year: 2017
RTP main game: 97.24%
RTP bonus feature: 97.77%
Variance (volatility): medium to high
Max win: 20.000x the bet
Cost Bonus Buy: 100x the bet

Let the magic show begin. With the free spins. How convenient that you can buy them right away!

You get 15 free spins, and there are 5 reels with up to 7 symbols. However, if you spin a cupcake on a reel, the reel expands with one extra symbol. Up to a maximum of 12 symbols. Per reel!

If everything goes well, you end up with 5 reels with 12 symbols each. It is good for as many as 248,832 Megaways.

Yes, then it must “a piece of cake” to conjure up some fantastic wins.

Nr 3: Punk Rocker – Nolimit City

Year: 2020
RTP main game: 96.01%
RTP bonus feature: 96.44%
Variance (volatility): high
Max win: more than 15,000x the bet
Cost Bonus Buy: 80x or 238x the bet

Punk Rocker is one of CasinoHipster’s favourite slots of all time and provides insane thrills. Imagine yourself as an East Londoner punk. You run away from the cops. Besides squatting buildings, a large part of your life takes place in the London Underground.

With the free spins, you get plenty of fireworks thanks to the many boosters and features.

You have two options. The Anarchy Free Spins (cost 80x the bet) and The Civil War Free Spins (for 238x the stake).  The latter comes with heftier multipliers and simply more boosters and fireworks.

The wins aren’t too shabby, either. I have seen wins exceeding 2,000x the bet. Can you outsmart the cops? 

No. 4: Extra Chilli Megaways – Big Time Gaming

Year: 2018
RTP main game: 96.41%
RTP bonus feature: 96.82%
Variance (volatility): medium to high
Max win: 20.000x the bet
Cost Bonus Buy: 100x the bet

If you buy the free spins, you get 8, 12 or 16 free spins. It depends on the number of scatters.

What’s so exciting is that you can increase the number of free spins up to 24, with the Gamble feature.

It matters how many free spins you get to play with. As with many Megaways slots, your multiplier goes up by +1 after each winning combo. Yes, if you have more free spins, you have more chances to build a high multiplier.

In short, will you dare to go for the MAX?

Nr 5: Rick And Morty Megaways – Blueprint Gaming

Year: 2020
RTP main game: 96.55%
RTP bonus feature: 97.16%
Variance (volatility): medium to high
Max win: 50.000x the bet or €250K
Cost Bonus Buy: 150x the bet

This Blueprint Gaming slot was an instant hit, thanks to the three very different Free Spins bonus features, the attractive RTP, and, of course, the hilarious theme.

Here, you’ve got the:

  • Pickle Rick Free Spins (mainly multipliers)
  • Federation Wild Spins (mainly extra wilds)
  • Vindicator Free Spins (cash prizes)

By spinning the Bonus Wheel, you’ll find out which of the three free spins bonuses you get and with how many free spins (5, 10, 15 or 20 free spins).

All three bonus features provide tremendous fun. Wins can be as high as several thousands of times the bet!

No 6: Hellcatraz – Relax Gaming

Year: 2020
RTP main game: 96.46%
RTP bonus feature: 96.83%
Variance (volatility): extremely high
Max win: 50,000x the bet
Cost Bonus Buy: 200x the bet

Hellcatraz is a stunning Relax Gaming slot, based on the famous island and prison (in the last century), Alcatraz.

The idea is to crack a golden safe and escape afterwards. You need to outsmart cops, guards and sharks. It reminds me of the famous film Escape from Alcatraz.

This slot is extremely volatile, and the max win is an astonishing 50,000x the bet!

You can get the free spins by collecting points. Luckily you can also buy these. A combination of collecting and buying (at a reduced fee) is also possible.

No 7: Deadwood – Nolimit City

Year: 2020
RTP main game: 96.03%
RTP bonus feature: 96.11%
Variance (volatility): extremely high
Max win: almost 14,000x the bet
Cost Bonus Buy: 71x or 750x the bet

Deadwood is an incredibly brutal Wild West slot, where the wins can be astonishingly high. I’ve seen several wins above 5,000x. And this slot has been released, only a couple of months ago!

But what else would you expect? You need to pay a more than hefty 750x the bet to get access to the free spins bonus that has the most significant potential.

If you do, you’re talking about the Shoot Out Free Spins, which gets you nudging wilds with multipliers and multiple symbols changing into wilds.

No. 8: Fat Santa – Push Gaming

Year: 2018
RTP main game: 96.45%
RTP bonus feature: 96.45%
Variance (volatility): high
Max win: more than 6,000x the bet
Cost Bonus Buy: 80x the bet

Fat Santa is a lovely Push Gaming slot where Santa Claus is calling the shots. The more biscuits he nibbles, the more generous he becomes with prizes.

With the free spins, he whirls through the screen like a kind of “walking” wild.

But if he eats five cookies, he becomes a symbol of 2×2. After again another five cookies, he becomes 3×3 in size. Then he’s already a colossal walking wild.

But he can even become bigger, and eventually, become 5×5 in size! Yeah, with a wild of 4×4 or even 5×5 size, it is going to be a fantastic Christmas party!

No 9: Serengeti Kings – Netent

Year: 2020
RTP main game: 96.20%
RTP bonus feature: 96.70%
Variance (volatility): high
Max win: unknown but likely around 2,000x – 3,000x the bet
Cost Bonus Buy: 59x or 84x or 243x the bet

Serengeti Kings is, up to this day, the only Netent slot with a Buy a Bonus feature.

Serengeti is a jungle slot in the beautiful African Serengeti forest with stunning landscapes and savannas.

The idea is to collect as many lions and panther symbols as possible. The more you collect, the more these symbols help you. These can transform into Wilds, and if all goes well,  you also get extra multipliers.

It can be a fantastic jungle experience.

Nr 10: Montezuma Megaways – WMS

Year: 2019
RTP main game: 96.05%
RTP bonus feature: 96.19%
Variance (volatility): high
Max win: €250K
Cost Bonus Buy: 85x the bet

Montezuma Megaways takes us to the gorgeous Mexican Jungle and is a high variance slot with a beautifully executed Aztec theme.

It’s also a Megaways slot, and one of the better ones, at that – breathtaking and exciting.

Through the Montezuma Respin Wheel, you can win multipliers up to an insane 100x.

Yes, if you spin a few combos afterwards, you can simply add two zeros behind your wins. It can get crazy here.
