Bonanza Review

Last Update: 16.07.2022. Author: SlotCatalog.

Bonanza Megaways is a powerful, unusual and exciting slot from Big Time Gaming. It was first released in december 2016, and you’ll see from the get-go that you’re in for a very special ride here. It’s based on the Megaways game engine, and this means you can activate up to an astonishing 117 649 paylines. This alone should tell you that this is a must try slot, but there is plenty more at offer here also.

When you go mining for the big wins at Bonanza slot, you can place your bet anywhere between 20p and £500, and you have the possibility of winning up to 26 000 times your stake. This is a highly volatile slot, so don’t expect to win all the time. Bonanza is jam packed with exciting features, and we will discuss them all in this review.

Bonanza Slot Win Screen

Above the reels you’ll see an old fashioned mining cart that carries 4 symboles. This happens on every spin, and increases your winning opportunities. The whole mining theme is very well done, and the stone symbols explode to give room for new symbols on every spin. This is a must try gem of a slot, but you have to be prepared for some patience when it comes to the big wins.

Bonanza RTP, variance & technical data

Before we drill deeper into the essence of this slot, and reveal all the exciting features, we will sum up the technical data for you:

  • RTP: 96%
  • Volatility/Variance: High
  • Layout: 7x7x7x7x7x7
  • Paylines: Uptil 117649 (both ways win)
  • Bonus features: Free Spins, Multipliers, Multiway (+1024), Substitution of winning symbols and Wilds
  • Bets: 0.2 to 500

The RTP of Bonanza is 96%, which is more or less exactly the average that you’ll find on most online slots. Return to Player is, as you might be aware, a theoretical number indicating how much you can expect a given slot to pay out in the long run. This gives us a house edge of 4% for Bonanza slot, and you can’t really complain about that.

The volatility - or variance as it’s also called - is very high on this game, so expect some turbulence on your bankroll and prepare accordingly. Big wins will come, but you need a cool head, and some patience with this game. Once you hit that massive multiplier in the free spins game, it will all be worth your while.

Bonanza Megaways Review

Bonanza Megaways slot is literally a gold mine for players who can handle the high variance, and it’s a very innovative game from Big Time Gaming. The game is wildly popular in the UK, and many other countries too, and it’s without a doubt the best game to come from BTG, so far. This does not in any way reflect negatively on their other games, as this provider has a great catalog of games worth checking out.

The variety of game play seen on Bonanza is nothing short of amazing, and with up to 117 649 ways to win, you know you’re in for a wild ride. The setting is a nice and harmonious mountain valley, with the mining cart on top of the reels, and an idyllic water mill to the right of the reels. The mining cart “mines” new symbols every round, coming horizontally in on top to interact with the vertical reels.

The more symbols that land in position, the more interaction you'll see, and there is so much going on at every spin that you’ll never find time to bored with this game. There is even an unlimited multiplier that keeps growing for every consecutive win in the free spins bonus feature, and, in theory, you can even get unlimited free spins. Don’t worry if it all seems overwhelming, we’ll go through each feature in detail below.

Bonanza bonus features

The free spins feature is the big attraction, and the heart of this game. However, the cascading reels and disappearing symbols is also worth mentioning.

Cascading reels

Every symbol that is involved in a winning combination will explode, and leave room for new symbols to form new winning combinations. This goes on as long as you keep winning, and it also plays an important role in the free spins feature we’ll describe below.

Bonanza free spins

Since this is a mining game, what could be more suitable than triggering the free spins feature when you spell the word GOLD anywhere on the reels. You’ll be rewarded immediately with 12 free spins, and for every extra scatter you land, you’ll get an additional 5 free spins.

Once the free spins feature starts, you’re taken into the mine itself, and every time you get a consecutive win, the “eternal multiplier” is increased by a factor of one. Land some early wins, and the multiplier can really get going towards the end of the feature, and your winnings will be huge.

You can also win extra free spins while playing this feature, and this is done by getting bars of gold in the mining cart. 3 gold bars will give you 5 more free spins, and 4 bars will give you 10 new spins. There is no limit to how many extra free spins you can win, just like there is no limit on how high the multiplier can go.

How to play

For being a Megaways title, Bonanza does not come with all that many options you need to know about before you get started. Even so, we shall run through everything here, so you are sure not to miss out on anything potentially important.

The first thing you can check out is the paytable. This is not a dynamic paytable that changes according to your chosen bet level, but instead it displays how much you win times your total stake for each symbol. There are 4 premium symbols in the paytable, and they are all different colored gemstones. The most valuable symbol pays 50x your stake for 6 on a payline.

If you click on the options tab in the menu, you can turn on or off the sound of the game. Unfortunately, you cannot turn off only the music, and keep the sound effects, like so many other games allow you to do. You can also read all about the game features in the paytable section of the menu.

Bonanza Slot Free Spins

To get started with the game, you first need to choose your total stake between 20p and £20, and then you need to decide if you want to play manually or use the autoplay feature. You can choose between 5 and 100 autospins, and you can also set a loss limit and a single win limit which stops the feature in its tracks.

The train carts you see rolling in on top of the regular reels each carry a symbol. These symbols add an extra row to reels 2, 3, 4 and 5 for every spin. Each row can display between 2 and 7 symbols, and the cascading wins feature allows for more than one payout per spin. That’s pretty much it when it comes to how to play Bonanza Megaways slot, and we wish you the best of luck!

The 200 Spins Bonanza Megaways Experience

The time has come for us to report how our test run went on this volatile game, and we knew exactly what we were getting ourselves into before we got started. We expected plenty of dead spins, and it took us around 20 spins to even get a minor 1.5x win. Mining is a tough business, and that is certainly reflected well in this game.

Between all the dead spins we had some decent 12x, 16x and similar wins, and this was due to the cascading feature which basically helped us break even over the first 100 spins. We found the delay between the symbols exploding and the symbols dropping down to be a bit annoying after a while, and wished Big Time Gaming had included a fast spin option.

Things took an exciting turn around our 150th spin, as we - by some miracle - managed to spell out “g-o-l-d” on the first 4 reels. It certainly felt like we had finally struck gold, and the setting shifted dramatically from day to night. The soundtrack also changed dramatically, and we received our 12 free spins and some info about what to expect.

Our pulse immediately went up, as there is no telling what can happen when you’re playing with an unlimited progressive win multiplier that does not reset between spins. Unfortunately, this was not really our lucky day, as we only managed to get the multiplier up to 6x. In the end, we landed a total win of 24.9x, which was a bit of a downer.

That’s how it is with highly volatile games however, so we cannot really complain. The rest of the 200 spins played out pretty much as before, and we ended up more or less breaking even in the end. Keep in mind that this is our highly subjective experience and first impression of Bonanza, and you might have a lot more beginners luck with this game than we did.

Bonanza jackpot (max win)

There is no progressive jackpot to be won at Bonanza Megaways slot, but you can certainly take home some serious cash from this game. Win up to 26 000 times your stake. It all depends on how successful you are in the free spins game, and how high your multiplier goes.

Bonanza Megaways mobile & tablet

Bonanza slot is available to play on any mobile device or tablet, and this is certainly a game worth having in your pocket. Play using Android, iPhone, iPad, or any other device you might have. Windows and Blackberry works fine too. It’s a great slot for handheld devices, and you’ll be sure to have tons of fun wherever you take it.

SlotCatalog verdict

Bonanza is a dynamite slot that everyone should give a chance. The Megaways engine offers plenty of action as usual, and the design of this slot is something we’ve hardly seen before. The heart and soul of the game is the free spins feature, but the cascading reels feature makes for plenty of fun playing the normal game modus too.

The high volatility can probably scare some people off, but you can always adjust your bet level accordingly. The potential for huge wins is always there, not least with the eternal multiplier and eternal free spins feature. Whenever you trigger the free spins, and are taken down into the mine, the rush of adrenaline will be well worth the wait. Who knows just how much you’ll win this time.


  • 117 649 ways to win

Kanske den bästa slots som gjorts hittils! Älskar denna Slot!. Hot Chili är inte dum den heller men oftast gamblar men ju med Free-spinsen och alltid lika surt när man går bust...

Johan** 2021-03-19 09:54

Does anyone know who has done the math to Bonanza?

parsi** 2021-03-19 11:32

Unfortunately very often people in the gaming industry are not willing to disclose the people behind the game. Contact us in case you want to get more info about Magaways mechanic creators or about the Bonanza slot itself.

Lars.** 2021-10-15 17:06

Great game. The original Magaways game is still the best in my opinion. Love the storyline of Monopoly Megaways but winnings have been slim there

Erik.** 2021-12-30 10:12

Is it just me or did this game start to pay out lot less? Probably have 3000 spins without triggering the "Gold" feature.. Any RTP changes you are aware of SlotCatalog?

parsi** 2021-12-30 12:50

Bonanza SlotRank Calculation

SlotRank - is the rank of the game popularity in the specific market. We are calculating SlotRank based on the gathered data from the online casinos. Daily our crawling system scans thousands of casino sites. From each casino sites we are getting list of games, lobbies screenshot, and list of games in the lobby. Important parameter of games popularity is average games position in the casinos lobby. To calculate Average position in the casinos lobby (APL) for Bonanza, we are using formula:

APL i = (450i + (282i - 23i) * 151 i) / 282i = 140.28

282 - quantity of valuable casinos with high weight in the United Kingdom. (Each casino gets weight. Casino weight is relevant to estimation of Internet traffic)
450 - Summa of positions in the casinos lobby
23 - Quantity of casinos that put game into the lobby
151 - We put size of casino lobby as 150 games. 151 - means that game is not in the lobby.

For the SlotRank calculation we are using SlotRank Value (SRV) parameter. SRV is sum of points that game gets for positions in the casinos lobby + points for presence in casinos + very minor value for game release date.

SRV i = 704.930i + (13.279 / 5000)i + ((0.1 * 17142)i / (5000 * 36500)i) = 330.334

SlotRank - is position in the game list sorted by SlotRank Value. Points that Bonanza gets for positioning in lobby:
704.930 = SUM ((151- Lobby Position)* CRV)
CRV (Casino Rank Value). CRV - is casino weight coefficient from 0.1 to 1 that gets each casino according to their traffic estimation.
Lobby Position - position in the casino lobby. We are measuring position for TOP 150 games. Highest position means that game placed on top left position in the casino lobby.
Maximum possible quantity of points gets game that top positions in casinos with higher CRV.
