Best Buy Bonus Game Slots (Highest RTP, Free Play): Guide + Full List

Full list of slots with buy bonus game feature
By Bonus game in this context I mean both: Bonus game as a separate round of the slot game and Free spins round. So to say, when you see an online slot offering to buy a bonus game, it might be either of them, not only Bonus game in the traditional sense.
Also there is no naming convention across the board of software providers when it comes to buying a bonus game. As a result, it can be called differently: “Feature drop” (Big time gaming), “High roller bets” (Isoftbet), “Big bet” (SG games). Though the majority of software providers call it pretty much straightforward: “Buy bonus”, “Buy feature” or “Buy free spins” (Relax gaming, NetEnt, Microgaming, Pragmatic, Blueprint).
How Buy bonus game feature works
In online slots with bonus features (Bonus game and Free spins), there is always some probability to trigger it. Normally probability to hit a Bonus game is somewhere around 1-2% per each spin you make.
Buying a Bonus game, you overcome the waiting part. This is the whole point of buying a bonus game, because in the real world 1-2% to trigger a Bonus game is only theoretical numbers. In reality, you can trigger a Bonus game within the first 10 spins or even 300 spin might not be enough.
So with the Buy bonus game you don’t have to rely on luck anymore. Just pay the “theoretical price” of the Bonus game and get it right away.

Buy bonus game and RTP
It is not uncommon to have a bit higher RTP if a player has chozen to buy a bonus game. Usually, it is only 0.1-0.2% higher than RTP in regular game mode so that it doesn't make a big difference. Anyway, higher RTP is always better, no doubt about that, but should not be chased at any cost, since it is not too much higher.
Types of buy bonus game feature
Depending on what bonus feature you buy:
bonus game as a separate round
free spins round is the most popular
multiplier can be offered on top of free spins
some combination of three of them (here we are only limited by imagination of slot producers)
Depending on what choices you have:
only one option offered
different types can be bought, so a player has to make some choice (for example, you can choose how much of free spins you would like to buy: 8, 10 or 12. The price is going to differ accordingly)
In terms of price of buy bonus game:
standard price of bonus game (x50-x100 times is what you can expect as a rule of thumb)
extremely volatile offers (here we may have numbers that go far beyond x100, for example, x750 in Deadwood slot)
Should players buy a bonus game?
From the very beginning I would like to remind you that buying a bonus game does not allow us to overcome the eternal gambling limitation that “the house always wins”. In other words, whether you buy a bonus game or not, you are still going to lose money in the long run. Though to the credit of the buy bonus game feature, it sometimes makes RTP a little bit higher for players.
Anyway, let’s take a look at pros and cons so that you can better judge how suitable the buy bonus game is for your needs.
Arguments for buying a bonus game:
Sometimes a bit better RTP than in normal game mode
You predictably get a bonus game for fixed price so that luck does not play any role (though it still does during the bonus game itself)
Arguments against buying a bonus game:
The Buy bonus game smooths volatility level (why high volatility is actually good for players)
Bonus game does not guarantee a big win, and you can easily end up without any significant winning
The buy bonus game is arguably more addictive than playing in regular mode
Buy bonus game and responsible gambling
The UK gambling commission certainly feels that the buy bonus game feature may be harmful for casino players. That’s why they have basically banned the buy bonus game feature in their jurisdiction.
source: Remote gambling and software technical standards (http://www.gamblingcommission.gov.uk/PDF/Remote-gambling-and-software-technical-standards.pdf)
I would rather agree with the UKGC, because the buy bonus game involves us in much higher stakes than we normally would play. So keep in mind that it can be addictive. On the other hand, I don’t agree that software providers deliberately design the buy bonus game to get us hooked up. In my opinion, it brings much more fun to the table, and this is the main reason why this feature was introduced.
Can I buy bonus game in progressive slots
You can do it in some progressive slots (for example, Dark vortex). However, by buying a bonus game, you do not affect chances to trigger the progressive jackpot. So these two features co-exist independently.
If we are talking about a separate bonus game (only during which you can hit a progressive jackpot, like it is done in Mega Moolah), there is no way to buy it. It must be triggered on a pure random basis.
Conclusion
The buy bonus game feature definitely makes gambling experience more diverse and interesting. That’s why we are going to see more and more slots with this feature as software providers are getting very positive feedback from players.
