What are the best paying slots with a Buy a Bonus Feature?

Buy Bonus Feature slots are emerging rapidly and these usually have high RTP’s

Slots with the Buy a Bonus feature (or Bonus Buy Feature slots) are becoming incredibly popular. In 2019-2020 we saw over 100 of these slots.

Take, for example, Nolimit City, Relax Gaming, Pragmatic Play or Netent.

  • Nolimit City did not release one single slot with a Bonus Buy Feature until 2020 when released 14 in total!
  • The same for Relax Gaming. Only 1 in 2019 but 8 in 2020.
  • Netent started in 2020. Now the incredibly popular Dead or Alive 2 comes with the Buy feature.
  • Pragmatic Play released 10 Bonus Buy slots and 8 of these in 2020.

Big Time Gaming was the first provider to introduce this with White Rabbit Buy a Bonus Feature. Another brilliant idea from this Australian slot provider, who also invented the famous Megaways mechanic!

Many players love slots with such a feature. The main advantage is that you access the free spins straight away, without the need to “struggle” in the main game. If you’re impatient, it works perfectly.

Another advantage is the higher Return to Player.

The RTP of Feature Buy slots, compared to the RTP of the main game

Below we have the RTP’s of all Feature Buy slots of 22 providers.

The blue dots are the RTP’s of the main game (base game) of these slots and the red dots are the same slots’ RTP’s if you opt for the Feature Buy.

The Feature Buy’s RTP’s are way more attractive than the RTP’s of the main game. Online Casino’s like players to increase the stakes and offering more attractive payout percentages is an effective way to incentivise players.

Besides, there’s a lot of competition. Would you, as a player, not be more interested in playing a slot with an RTP of 98% rather than 96%?

The Buy a Bonus Feature slots with the highest RTP

Below, the top 20 list. I looked at all Buy Bonus Feature slots up to December 2020.

FEATURE BONUS BUY – best paying slots Provider Year RTP  Bonus Buy /Main Game
1. Morgana Megaways iSoftBet 2017 98.06% / 95.98%

17. Ted Megaways Blueprint 2019 97.00% / 96.03%
18. Western Gold Megaways iSoftBet 2020 97.00% / 95.98%
19. Euphoria iSoftBet 2020 96.97% / 95.99%
20. Big Cat King Megaways Blueprint 2020 96.91% / 96.50%


You see, many of the slots have an RTP topping 97%. There are actually some slots with a Return to Player of 98%.

Money Train 2 and Money Train, a couple of fantastic Relax Gaming slots, have an RTP of 98% if you choose to play the Buy a Bonus Feature. In the main game, these percentages are 96.4% and 96.2% respectively. It matters!

Kalamba slots are not on the list. Kalamba released 31 slots with a Buy a Bonus Feature and some 10 of these have RTP’s ranging from 97.5% and 98%. You need to be careful, though, as it only applies for the highest bet level (if you increase the stake to the highest level).

Why a higher RTP matters a lot

The higher the RTP, the better it is for you. If, for example, the RTP is 96% you’ll lose $€4 after every $€100 you wager. But would the RTP be 97%, you would “only” lose $€3 after every $€100 you wager.

You can argue that the 1% difference is not so significant. But it matters. For example, you could have a starting balance of $€100, but your total wager during a session may be $€500. Don’t forget you often stake your winnings, as well.

  • If the RTP is 96%, your expected loss is: $€500 x 4% = $€ 20
  • If the RTP is 97%, your expected loss is: $€500 x 3% = $€ 15

You can see that the difference is already more substantial. And it becomes larger and larger once you start to wager higher amounts.

The RTP has nothing to do with the volatility (or variance) of the slot. Variance says something about the variation of the sizes of wins. High volatility slots pay more top prizes (but less often).

Low variance slots pay out smaller prizes, albeit it more often. 


Conclusions – Slots with a Buy a Bonus Feature usually have attractive payout percentages

There are more than enough Buy Bonus Feature slots with attractive RTP’s. It pays off looking for those with an RTP of 97% or more.

There is plenty of choices, and that will increase going forwards. I saw over 80 slots in 2020, and I expect to see at least another 100 of these in 2021.

What about the best paying slots by other providers?

Do you prefer to mix it up a little, from time to time? We all do.

Sometimes you feel like playing a Megaways slot, and other days you might want to have a go and play some Netent or Play’n GO slots.

And don’t you want to know which ones have the higher RTP and which ones don’t?  If you do, please check:
