100 Spins Test

This 100 Spin test was updated by Steve Madgwick on 07/12/2023

100 spins is not a Real Test

We give every slot a 100 spin test to see just what it can do, or not as the case can often be - 100 spins is no reflection of the likelihood of any other 100-spin session, as RTP's are set over many millions and probably billions of spins. So this 100 spin test is just for entertainment and insight purposes

Session RTP24.1%

Test Comments

A reskin of the classic pragmatic game which comes with the same volatility, on which this test fell on the wrong side as demonstrated by a very poor 24.1% RTP for the session, producing just 13 winning spins from the 100 played, with an average winning spin value of just 1.84x which alone was bolstered by a 10x win on the very first spin.

It is just Big Bass in another form, and nothing to get over excited about unless its your favourite game and you want to add a festive feel.

Game Data


Whether you're a newbie or a seasoned pro when it comes to the Big Bass slot games you've probably seen them around. This is the 12th game in this hugely popular franchise of games. This one comes with a Christmas theme to get you in the mood for the festive season.

Graphics, Music, and Sound Effects

The music is Christmas, Christmas, Christmas. Which is a dream for some and a nightmare for others, depending on which side of the fence you sit on. Personally, I love Christmas so bring on the cheesy tunes.  

Sound effects include the sound of a snow plough plus the traditional slot game sounds that are usually part of the Big Bass experience. 

The graphics are bright and cheery and include the usual Big Bass style fishing imagery with the addition of a few Christmas creatives sprinkled in.

Key Features

Right, now that I've covered the summary, intro, graphics, music, and sound effects, up next are the key game features.

At OLBG we create slot game reviews that include current info about essential features such as the theme, paylines, reels, bet range, and bonuses. I’ll finish off the review by talking about my play experience, first impressions and expert verdict.

Theme – Christmas

Deck the halls and all that - Christmas is just around the corner, so the Christmas 2023 slot games are ramping up. There is so much scope with a Christmas theme, take your pick from tinsel, trees, candy canes, Santa and stockings - the list is endless. In the background of this game, you'll see the usual Big Bass underwater scene complete with bubbles and weeds. This one randomly has candy canes, presents and fairy lights thrown in for a bit of seasonal good measure.  At the top of the screen, the scene is quite different with an iced-over lake and snow-topped alpine houses. The bonus round has the same view with the addition of the progress bar at the top of the screen.

On the reels - in order from highest first - you'll find a snow plough, fishing rod, dragonfly, tinsel-covered bait box and a selection of fish. After this are the standard A, K, Q, J & 10 symbols. 

The special symbols include the Fisherman Wild which is the Fisherman dressed up as Santa and the Money Symbol which is a selection of fish.


The Big Bass Christmas Bash game is made up of 5 reels and 3 rows to play with. 


There are 10 non-adjustable paylines where you can trigger wins.


Return to Player is most commonly referred to as RTP, you've probably seen this acronym on slots sites. It's a way of forecasting theoretically what percentage of a player's stakes will be returned to them over the long run. The higher the number the better and ideally the rate should be 96% or above. Big Bass Christmas Bash is a high rate at 96.71%.

This RTP figure is used as a default value by  Pragmatic Play so if you shop around you’ll discover several rates. To save you some time, we’ve uncovered a few at some of the popular UK online casinos and added them to the table below.

It's worth mentioning that RTP is just one consideration when deciding which site to play at. Other factors include payment options, game library, customer support and welcome bonuses and deals. Our casino reviews look at this info and much, much more.

Stake Range

The Big Bass Christmas Bash game has a wide bet range which starts at £0.10 and goes right up to £250.

Max Win

The max win amount for the Big Bass Christmas Bash slot game is 5,000x your stake.

Wild Shape

The Fisherman Wild Symbol represents the Wild shape of this game. He appears on all reels during the Free Spins round, He substitutes for all symbols apart from the Scatter Symbol. During the Free Spins feature, each Wild Symbol collects all the values from Money Symbols on the screen and are counted up at the end of the round. Every 4th Wild Symbol collected retriggers the feature, awards 10 more free spins and the multiplier for money symbols collection increases to 2x for first retrigger. And then 3x for second retrigger and 10x for the third retrigger.

Free Spins

To enter the Free Spins round you must land 3 or more Scatters. If you land 5 Scatters = 20 free spins, 4 Scatters = 15 Free Spins and 3 Scatters = 10 Free Spins. If you happen to land 2 Scatters in the base game there is a second hance for another one to be brought down in the reels by a random feature. If the scatter can move down one position a respin can be triggered. Alternatively a hook can pull the reels up to reveal another Scatter. 

Just before the Free Spins round starts 0-5 modifiers that apply to the subsequent round are randomly selected. The 5 modifiers are - more Fish Symbols, more Fisherman Wilds, more Dynamites, Hooks and Bazookas. Or you can start from level 2 which gives you a head start. Lastly, you can receive 2 extra free spins – you start with 2 free spins plus you receive 2 extra free spins on every retrigger.


Like most modern-day slot games, Big Bass Christmas Bash doesn't have a jackpot element. If jackpots are your thing you should visit our page with the best jackpot slot games.

Play Experience & First Impressions

The base game does what it says on the tin - it's pretty basic and looks like most Big Bass games just with an added Christmas element. The Money Symbol part of the game was fun. Here, the symbols showing a selection of fish have two uses, firstly it’s a paying symbol on the reel. Secondly, it’s also a Money Symbol. During each spin, the fish takes a random money value which you can win during the Free Spins feature. The values range between 2x – 5000x your stake. If you trigger a larger amount it can mean decent wins. 

I enjoyed the Free Spins round as it was straightforward to understand. You need at least 3 Scatters to trigger the bonus round, however, you get a second run at it if you only trigger 2.  Here, randomly there is a chance for another one to be brought down in the reels - either the scatter can move down one position or a respin can be triggered which was a cool functionality. And it's great when it randomly triggers when you're playing. The modifiers at the start of the round were also a great addition as you then know you're going to receive more of a certain symbol or function during play which adds to the excitement.

Expert Verdict

As mentioned in the summary section, this is the 12th game in the series so I wonder when this franchise is ever going to end? Like the TV series you enjoy but which ekes it out for way longer than it should, it feels like forever. Obviously, there must be umpteen amounts of fishing-themed slot game lovers out there on the planet. The last Big Bass game I reviewed was Big Bass Amazon Xtreme and before that, there was Big Bass Bonanza and Big Bass Splash which were all pretty similar and light-hearted. The RTP rate of 96.71% is impressive and is higher than most slots on the market and is certainly higher than its predecessors. 

The features were enjoyable but the imagery and story didn't feel that special, I guess it is just a reskin of previous games. This is the first Christmas slot game I'm reviewing for 2023 so it's fun to see a festive theme but maybe I'll feel differently in a couple of weeks' time. All in all, I'd say give it a go, I can't say that it has reeled me in but fans of the Big Bass games won't want to miss it.
