Buying the bonus round in slots: what you pay and what you get
Bonus buy is a button inside a slot that starts the free spins straight away instead of waiting for scatters. You pay a fixed price, usually 100 times your bet, and the bonus begins in the same round. It is not a shortcut to winning; it is a way of paying for entry into the most volatile part of the game. Below: how the price works, what the RTP of a bought bonus means, how buying differs from a normal spin, and which of our slots offer it.

How bonus buy works
In normal play, free spins start when enough scatters or bonus symbols land. That does not happen often: in our bonus slots the feature arrives rarely and dry spells can be long. The buy button removes the waiting. You confirm the price and the slot opens the bonus mode at once, in the same round.
The maths inside the bonus does not change. Buying does not make free spins more generous; it only changes when you enter and what the entry costs. Most free spins in these slots pay nothing, and one to three spins usually carry the whole bonus, so a bought bonus is just as uneven as one that triggers naturally.
What a bonus costs, with examples
The price is a multiple of your bet. Most often it is 100x; a few games use 120x or 125x. With a $0.50 bet the bonus costs $50, with a $2 bet it costs $200, and at the $100 maximum bet one purchase costs $10,000. The price is shown on the button itself before you confirm, so check both the stake and the total.
A useful habit is to compare the bonus price with your bankroll, not with a single spin. One purchase at 100x burns as much as a hundred ordinary spins, and the outcome is decided in a handful of bonus spins.
The RTP of a bought bonus
Our design target is that a bought bonus returns roughly the same RTP as the game itself, within about half a percentage point. Buying should not be noticeably better or worse than playing normally. But RTP is an average over a very long run. In a single purchase you will usually get back far less than the price, and in rare cases far more.
The Theoretical RTP of each slot is printed in its info panel, and that figure is the one that counts, because the operator sets RTP per game. For the basics, read the RTP guide, and for the spread of results see the piece on volatility.
Ante: the other way to speed up the bonus
Some slots offer Ante: a higher chance of the bonus in exchange for a more expensive spin. Storm Titan Kaelos has it. It is not a purchase. The bonus is not guaranteed; you simply come closer to it more often and pay more for each spin. If you play with Ante on, count the real cost of a spin, not the number on the bet selector.
Our slots to check for a buy button
Storm Titan Kaelos: a 6x5 grid that pays for 8 or more matching symbols anywhere, with multiplier orbs that add up in the bonus. It has both Ante and a buy option.
Fallas: 6x6 blasts and a cell multiplier ladder from x1 to x12 in the bonus. Bonus buy is listed on the game card.
Jade Dials: dial wheels add up to one multiplier that is kept for the whole bonus, up to x189. A bonus built on an accumulating multiplier leans heavily on luck, so the purchase price carries real risk.
Troika Trail: a walking wild and a bonus ladder of x1, x3, x4, x6 and x18. If the button is there, the price is visible before you confirm.
Golden Bananas: the top win here is x10000, the highest among our bonus slots, which means very long gaps between big outcomes.
What to check in the info panel before buying
Open the rules and look at three things:
- The slot's Theoretical RTP, which applies to normal play and to a bought bonus alike.
- Max win per round, shown as a multiple of the bet: up to x5000 for our bonus slots, x10000 for Golden Bananas.
- The bonus price on the button: convert it to dollars and compare it with what you are ready to lose in one go.
Wagering and bonus buys
While a bonus is active, bonus buys do not count toward wagering and are played with real money only. The details are in the wagering guide. Buying a bonus round to clear the terms faster does not work. For a longer walk-through see the bonus buy guide. You must be 18+; play responsibly.
Frequently asked questions
Does bonus buy raise my chance of winning?
No. Buying changes the moment you enter the bonus and its price, not the maths inside it. The designed RTP of a bought bonus is close to the game's RTP, so over a long run you still get back less than you stake.
How much does a slot bonus cost?
Usually 100 times the bet, and 120x or 125x in a few games. The exact price is on the button before you confirm. With a $1 bet, a 100x purchase costs $100.
Can I buy a bonus in demo mode?
A guest plays slots in demo only, with a $10,000 demo balance that can be topped up for free. The buy button there is for learning the mechanic; it does not involve real amounts or real payouts.
Does a bought bonus count toward wagering?
No. While a bonus is active, bonus buys, instant games and provider games do not count. Only slot bets paid with bonus money are counted.
What is Ante and how is it different from buying?
Ante is a more expensive spin with a higher chance to trigger the bonus. The bonus is not guaranteed. A purchase starts it at once for a fixed price. Storm Titan Kaelos is one slot with Ante.
Which RTP figure is the right one for a slot?
The one printed in the game's own info panel as Theoretical RTP. The operator sets it per slot, so trust the number inside the game rather than general claims.
