Mr. Bells 40 is one of the newer slots designed by Endorphina, and yet it has the look of a classic, featuring fruit symbols and a main character shaped like a golden bell. It might look like yet another retro slot, but its game area is larger than expected based on its look, with 40 paylines offered via 5×4 reels.
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 high volatility slot. Wins are rare, but can be really big. The game has more pronounced fluctuations and can often go without hitting anything for a long time, suitable for players who like adrenaline, higher risk and work with a larger budget. More about volatility here.
Slot theme and symbols
Endorphinaβs slot machine was designed to look like pretty much any other classic, at least when it comes to the chosen symbols and the style of the graphics. All those fruits and other classic symbols look like they were copied straight out of a 20th-century land-based machine, using the same dated look as they did back then. The part that makes it look different comes from its lead character, a Mr. Bell character that wears a big moustache, and itβs a companion for you as you play this 5-reel slot machine.
Mr Bells 40 theme and symbols
Give the slotβs demo a try if youβre not sure about it. Expect high volatility, either way. While the long-term prospects are fine, based on the announced RTP of 96.06%, I wouldnβt expect most players to get excited over the 2,900x top jackpot thatβs available in this game. It brings a mix of old graphics and some modern features, which some players might appreciate.

WILD symbol
One of the noteworthy symbols that you will find in Mr. Bells 40, the wild takes the form of the Red Seven. Itβs a symbol that may come in both regular and stacked variants, so there are times when it may cover an entire reel. Mostly, you get to use it as a substitute symbol, replacing regular symbols in winning combinations where theyβre needed. There is also the possibility to have 3 to 5 wilds form their own combo, and at that point, they pay the most out of all symbols that can form combinations.
Star Scatter symbol
The Star symbol is the scatter that shows up just to get you paid extremely well. It doesnβt trigger any features, but it doesnβt have to. Having 3, 4, or 5 Star scatters on the reels results in a win of 50x, 200x, or 1,000x the stake, respectively.
Bell Scatter symbol
The other special symbol, the Bell, acts as a scatter that has to land 6+ times to trigger a feature. The additional Bells required to get there may also come via the Lucky Time feature.
Bell Bonus Game
If you get the needed 6+ Bell scatters anywhere on the reels, you trigger the Bell Bonus Game. It consists of 3 respins/attempts, where you get the triggering Bells sticky, and you try to get more. The number of attempts resets when you get new bonus symbols to land. Each Bell will pay a regular prize (1x to 50x) or a jackpot (ranging from 10x to the 750x Ultra Jackpot). Get all 20 Bell symbols on the slotβs 5×4 reels, and the prizes paid by them will triple in value (3x multiplier is applied).
Risk Game (Gamble)
Winning spins will bring with them the option for you to either collect your winnings or gamble for a chance to double them. Itβs a Risk Game that involves a card game with the dealer. Whoever gets the higher card wins.

Our rating of the game
Mr. Bells 40
There is little to make Mr. Bells 40 a slot worth checking out these days, especially with the huge number of other slots that had the same idea: using retro graphics and a modern bonus game. The combination has been done before, plenty of times in fact, so itβs up to the slotβs high volatility, 2900x jackpot, and 96.06% RTP, to make it a favourite. As you can see, it doesnβt look like a very good combination.

How do we rate slot machines?
We evaluate slot machines based on multiple criteria, from which we make our final verdict.
Has a Hold & Win-inspired bonus game, with respins and plenty of opportunities to claim decent prizes.
Has a wild symbol that can land stacked, and it will also form the gameβs highest value combinations.
Its Star Scatter will pay up to 1,000x the stake, just by landing five times on as many reels.
Its RTP is expected to be 96.06% long-term, which is good enough for a slot.
Having Mr. Bell as a main character makes the very common fruit theme stand out.
Cons
Fruit-themed and other classic symbols, which you can get from a lot of older slots.
Highly volatile gameplay, so a lot of gaming sessions will result in a big loss.
It pays at most 2,900x the stake, which is a low return in a game with increased risk.
Dated graphics, so pretty much as expected in the fruit category.
