Slot machine details and review Hell Hot 40
Hell Hot 40, one of the fruit-themed slots from Endorphina, is available here in one of three versions (with either 5×3 or 5×4 reels, and with 20, 40, or 100 paylines). This particular version offers us 5×4 reels, and there are 40 active paylines present. This is a fruit-themed online slot that has a bit of a hell theme going on, seen in the fire that pops out in various places.
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
Visually, itβs the sort of look that you would find in much older games, which is very common to see in fruit-themed slots. As such, none of the symbols landing on its reels will surprise you. The backdrop is hell itself, but you donβt see much of that side in its symbols, with one or two exceptions. Only 6 regular symbols are present, so compared to other slots from Endorphina, itβs not that crowded, and forming combinations should be easier.
Hell Hot 40 theme and symbols
Hell Hot 40 comes with a cute top prize, worth 666x the stake, which is perfectly aligned with the hell side of its theme. On the other hand, itβs not taking it too hard on the player, keeping the volatility Low. Its RTP is also OK, being at 96.04%, so itβs considered a fair game, all things considered. Its mechanics are simple, with regular combinations of 3 to 5 symbols available, along with a couple of basic feature symbols.

WILD symbol
The Wild is one of two big symbols that have additional roles to play. Itβs a substitute symbol, usable in combination with regular symbols, helping you form more winning combinations. It will not replace scatter symbols, but it works with all other symbols. Furthermore, get 3 to 5 wilds on the same line, and they can form their own combination, the highest value in the game. The fact that it lands stacked helps it as well, since it can take 1 to 4 positions on a reel.
Scatter symbol
Another way to get paid very well is through the scatter symbol, the one featuring the Gold Star. This is a symbol that can land anywhere on the reels, as long as you have 3, 4, or 5 of them. The result would be a prize worth 5x, 20x, or 500x the stake.
Risk Game (Gamble)
The option to gamble winnings is always there in Endorphina slots, and the Risk Game is present here as well. You play a game of cards against the dealer, the aim being to double your winnings. Of course, you can also lose the roundβs winnings.

Our rating of the game
Hell Hot 40
Itβs one of three slots available with this name, so you can check out different versions of it, with 20, 40, or 100 lines. The one weβre looking at here is the middle-of-the-road option, with a decent number of lines, the same low volatility, and the 666x top prize that looks appropriate for this particular theme. At 96.04%, its RTP is at a good level, and the slot is considered fair. Itβs a good one to play casually or if youβre a beginner.

How do we rate slot machines?
We evaluate slot machines based on multiple criteria, from which we make our final verdict.
Stacked wild symbols are present, and they can pay directly or act as substitutes for others.
Scatter symbols will land and pay as much as 500x the stake if there are enough of them around.
There is a 96.04% RTP that you can go after, which is a fair amount in the long-term term.
Low volatility is good news if youβre a beginner or someone who doesnβt expect a life-changing top prize.
666x the stake is fine for a slotβs top jackpot, and here itβs especially appropriate with the Hell theme.
Cons
You get the same fruit-themed design as everywhere else, and the fire element is also common.
Dated graphics, similar to those found in land-based machines, so it goes for the nostalgia factor.
Short list of features, and basic ones at that, so you donβt get bonus games or free spins here.
