Slot machine details and review Inner Fire Bonus Buy
Released by Evoplay, Inner Fire Bonus Buy is a slot machine that was inspired by the classic fruit genre. Visually, it looks like a land-based machine, a slot with 5 reels that will deliver various classic symbols, ranging from fruits to sevens. The game area has 5×3 reels, always ready to spin together, while 10 active lines are present within, and can host winning combinations.
Every slot machine must be developed by a company that invented, designed and put it into operation. Many players eventually find that they only enjoy playing on machines from specific software provider, so they narrow down their selection by preferred brand.
A slot machine with low volatility. Wins occur frequently, but are usually small. The game has a smoother course without large fluctuations, suitable for players who do not like risk and work with a smaller budget. More about volatility here.
Slot theme and symbols
This fruit-themed classic slot will give you a mix of symbols, ranging from cherries to Sevens on fire. You get retro-style graphics in this case, so itβs not a modern version of those very popular old symbols. There isnβt much of a background image, either, just a dark red color that works well in connection with the golden rim of the slot machine. Out of the 10 symbols landing inside, 8 are regular ones, with which you form combinations.
Inner Fire Bonus Buy theme and symbols
Inner Fire Bonus Buy is described by Evoplay as a slot with Low to High volatility. Itβs likely a Low volatility but on the higher side. What I enjoy seeing here is the big top prize, going up to 10,148x the stake, which works great with the high hit rate of 43% (percentage of winning spins, on average). The RTP is also OK, at the 96% level thatβs been announced.

Scatter Symbol
WILD symbol
A Crown Wild can appear on all reels, and players will be able to use it as part of new combinations. Itβs a substitute symbol that works together with regular symbols to get you new wins, and itβs also capable of paying directly (if 3 to 5 wilds appear on the same line, left to right). Wilds canβt replace any of the feature symbols.
Silver symbol
These are silver-colored Dollar Sign symbols, which will act as scatters and pay when there are 3 or more present at the same time. The prize ladder starts from 1x for 3 Silver symbols, and goes up to 2,000x the stake if there are 9 Silver symbols.
Gold symbol
There is an even better version, the Gold symbol, but this one can land only once per reel and only during paid spins. The only way to take advantage of it is to get it to appear 5 times anywhere on the reels. If this happens, you get paid a Legendary prize, worth 5,000x the stake.
Scatter symbol
You will be able to use special scatter symbols, featuring the Free Spins logo, whenever they land on the reels 2-4. These are available both during paid and free spins.
Free Spins
If you manage to get three scatter symbols on the reels at the same time, you will trigger 10 free spins. These spins are played with doubled prizes, and this even applies to the Fire prizes, as Silver symbols now pay up to 4,000x. This feature can be retriggered if you get another 3 scatters.
Bonus Buy
For those who are impatient and donβt want to wait around for that 1 in 97 spins chance to trigger the free spins, there is the option to get access to it immediately. The price of this feature is 30x the roundβs stake, and if you use it, you get 10 free spins to begin immediately.

Our rating of the game
Inner Fire Bonus Buy
Inner Fire Bonus Buy gives you plenty of modern features to explore, has excellent prizes that can pay even during its paid spins, and it has a high hit rate thatβs coupled with a lower volatility rating and a chance to claim big prizes. It sounds great, on paper, with those wins of up to 10,148x the stake providing you with all the motivation you need to check it out. About the only downside I see with it is the classic theme and land machine-style view of the game area, for those players who donβt enjoy it.

How do we rate slot machines?
We evaluate slot machines based on multiple criteria, from which we make our final verdict.
Its Gold symbols can pay a 5,000x prize during the slotβs paid spins.
Silver symbols that pay as much as 2,000x during paid spins, and up to 4,000x during free spins.
A free spins feature where all types of prizes are doubled in value, even Fire Prizes.
Wild symbols are used both as replacements and to form their own high-value combinations.
You get the option to use the Bonus Buy, which is not that expensive (30x the stake).
There is relatively low volatility, and yet the game will pay over 10,000x the stake.
A 96% RTP is also mentioned, and itβs a good long-term return for any slot machine.
Cons
Itβs the same classic mix of symbols in a land-based machine form, which you can get everywhere.
You get only 10 active lines via the 5x3 reels, which spin each round.
It is a dated design, typical for this kind of theme, but which some players may not like if theyβre more into modern graphics.
