Bonanza slot is the first game to put Big Time Gaming and its Megaways engine on the map. The game was released just before Christmas in 2016, becoming an instant hit.
To those new to Megaways best online slots, this mechanic works as each reel shows a random number of symbol positions after every spin. For instance, the third reel can have anywhere between two and seven symbols.
It doesn't feature traditional paylines, as it's enough to only have matching symbols on subsequent reels, starting from the leftmost reel. This results in the Bonanza slot machine having 117,649 ways to win.
The game has six vertical and one horizontal reel. If you win, the winning symbols disappear, being replaced by new ones falling from above. Bonanza features great graphics for the time and has a catchy tune playing while the reels are spinning. Apart from an exciting base game, you can unlock the free spins round with an unlimited multiplier.
The Bonanza slot has a mining theme. The most valuable symbols in the game are differently colored gems and diamonds, the symbols on the horizontal reel are shown in mining carts, and symbol positions are actually rocks that explode once winning combinations are formed. The background shows a waterfall and a rocky terrain with the miner's house sitting in the corner.
There isn't much to say about Bonanza's storyline since there really isn't one. You won't see any characters or human figures. It's all just about mining for valuables.
Bonanza Graphics and Sound
This online slot's graphics are relatively solid, considering the game came out in 2016. The waterfall flowing behind the reels makes you feel as if the environment is alive, and watching the symbols explode every time there's a win is pretty fun, regardless of how many times you've seen it. The symbols are well drawn and distinct from each other.
The sound effects are also crisp and realistic. Catchy and adventurous banjo music plays only when spinning the reels, giving you the incentive to keep playing.
How to Play Bonanza
Bonanza is an easy game to master. But before playing Bonanza for real money, you must create an account on a casino site that carries this slot. You don't need to go anywhere to do that, as our team here at CasinoSmash has listed some trusted online casinos that feature Bonanza and other slot games.
Once you choose your casino, create an account, deposit, and claim the welcome bonus, you can load the game and start playing. All you must do before initiating the first spin is set your wager. Use the arrow button under the Stake tab to set your bet anywhere between $0.20 and $20. After you've set everything up, press the play button and start enjoying the game.
The Bonanza slot also has an autoplay feature that lets you kick back and relax while the spin plays through automatically. You can set anywhere between 5 and 100 automated spins. If you want to learn more about the game, you can access the menu by clicking the icon with the three lines. This is where you can toggle sound on and off and read about the game's rules.
Bonanza Features and Gameplay
Like many other Big Time Gaming slots, Bonanza uses the Megaways engine. As mentioned, Megaways work in a way that each spin spawns a random number of symbol positions on each reel. Since there are no traditional paylines, the Bonanza slot triggers a win if the symbols appear on adjacent reels from left to right, regardless of their position on those reels.
Each of the six reels in the Bonanza slot can feature between two and six symbol positions, but since there is an additional symbol above reels two through five via the horizontal reel, those reels can have a total of seven symbol positions.
Because of the random number of symbol positions, there's also a random number of ways to win on each spin. If all reels feature a maximum number of symbol positions, you can play with 117,649 ways to win.
Three symbols of the same kind must appear on the first three reels for a win to trigger, except for the most valuable symbol, the diamond, which can trigger a win even when showing on just two reels.
The cascading reels mechanic is in play on every spin, meaning that once you win, the winning symbols are destroyed and replaced by new ones falling from above. Symbols on the horizontal reel that become part of the reaction are replaced by new symbols from the right. This goes on until there are no more new wins.
The Bonanza slot has 12 symbols, including low-tier card mark symbols 9, 10, J, Q, K, and A, mid-tier green, blue, and red gem, and the high-tier diamond. Dynamite acts as the wild symbol and replaces all other symbols except scatter symbols. Scatters are shown as letters G, O, L, and D, and you must get all four to trigger the bonus game.
Bonanza is considered a high-volatility game. This implies that there's a big disparity between big and small wins and that massive wins are rare. Casual players can bet as low as 20 cents, while those seeking more risk can wager up to $20 per spin. The game's RTP is measured at 96.00%.
Bonanza Bonuses and Free Spins
The Bonanza online slot has only a single bonus game which is a free spins feature. To unlock the free spins, you must get four scatter symbols to appear during a single spin. Each scatter symbol is one letter, and once you get all four, they will spell G-O-L-D (the letters don't need to appear in consecutive order).
This unlocks the bonus round that initially starts with 12 free spins. The free spin scatters (gold bars) can appear during the round, but only in carts on the upper horizontal reel. Three and four carts filled with gold bars will award five or ten more free spins, respectively.
Once the round starts, the scenery changes. Instead of being outside, you are now inside the mine, with red and black mineral-filled rocks dominating the layout. The free spins round works similarly to the base game, but with one major difference — every consecutive winning combination now adds 1x to the unlimited multiplier counter.
In other words, if you got one win, the next one will count as double, the third win will come with a 3x multiplier, and so forth. The multipliers increase all the way to the end of the round.
Where Can I Play Bonanza?

The Bonanza slot machine is the game that popularized the Megaways mechanic and the main reason why there are now loads of slot titles featuring this engine. With six reels that constantly show a different number of symbols, you never know how many ways to win you're going to get the next time you press the spin button.
Getting big wins is rare, and so is unlocking the free spins feature, but once you get there, it will all be worth it. Twelve free spins are more than enough to get a huge payout, especially as you'll be helped by unlimited multipliers that increase after every consecutive win.
Other Popular Slots
We can all agree that the Bonanza slot is one of the best slot games in the world right now. However, it's far from being the only slot you should try playing online. For instance, you can't go wrong with Starburst, a simple 5x3 slot with a calming atmosphere ideal for novice players.
Immortal Romance is another classic many US players enjoy, and you just can't ignore the fact that it’s a high RTP slot at 96.86%. If you're all about adventurous slots and getting lost in the jungles of Latin America, NetEnt's Gonzo's Quest is the way to go.
Lastly, if you really like the Bonanza slot and its Megaways mechanic, you should look for some other Megaways slots and slots with cascading reels. Our recommended online casino operators should have plenty of those.
