Mr. Jingle Bells is one of the slots you will find at Endorphina casinos. Itβs a holiday-themed slot machine with three reels that adds Christmas-inspired decorations and baubles to its reels and surrounding graphics. The setup is simple enough, with just 3×3 reels ready to spin, while winning combinations will form via 5 active paylines.
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 with medium volatility. Wins occur occasionally and are balanced. The game has an alternating course without extreme fluctuations, suitable for players looking for a compromise between risk and winning potential. More about volatility here.
Slot theme and symbols
While Mr. Bells continues to be the star of the slot, just like in Mr. Bells 40, weβre looking at a more Christmas-oriented design everywhere else, not a classic with fruits. There is a Christmas-inspired pattern and snowflakes in the background image, while on the reels, weβre once again getting a mix of holiday-related symbols. Card suit-shaped baubles, snowflakes, gift socks and a couple of classics are going to be found within the 8 regular symbols that can land.
Mr Jingle Bells theme and symbols
Itβs not a very complicated game. In fact, you donβt get any real features, with the exception of the gamble game that you can trigger after each win, and the feature that applies multipliers to wins coming from certain symbols, if they take over the screen. Other than that, youβre just trying to form winning combinations, with 3 matching symbols being required on one of the 5 lines for that to happen. The result is an Endorphina slot that has medium volatility, an RTP of 96.01%, and a top prize that appears to be capped at 750x.

Jingle Bells Bonus Game
The slotβs only real feature, this bonus game will trigger if you get a single type of Christmas toy (the card suit-inspired baubles) in all positions on its reels. If that happens, you trigger the Jingle Bells bonus game. You have to make a pick, where youβre trying to find Mr. Jingle Bell. Depending on the number of correct picks you make, this can lead to 2x, 4x, or 8x multipliers being applied to those wins. Since these symbols pay at most 8x for a combo, with multipliers, they can get to 64x. Compared to the top symbolβs payouts of 150x, itβs not even half. Nonetheless, itβs a feature thatβs appreciated, since it makes the more common paying symbols much more valuable in certain circumstances.
Risk Game (Gamble)
You can choose to trigger a gambling feature at the end of any winning spin. You risk your winnings for that round, for a chance to double the prize. Itβs a card game where you have to get a higher card than the dealer to win.

Our rating of the game
Mr. Jingle Bells
If you like simple gameplay and youβre not expecting the sort of slot that will make you rich, then Mr. Jingle Bells could be the right choice for you. Itβs particularly interesting at Christmas, when there are not that many very simple slots for people to check out. This one doesnβt have any real features, with the exception of a multiplier that only applies in certain situations. The medium volatility makes it accessible, and the RTP looks fine at 96.01%. I wouldβve liked a higher top prize than the 750x that can be claimed through five combinations of the top-paying symbol.
