Bonanza is a lively slot set by a lush and rocky mountainside, full of precious gemstones and heaps of gold waiting to be unearthed! Upon release, Bonanza was one of the first casino slots games to introduce the Megaways concept to the iGaming industry. It was instrumental in propelling its developers, Big Time Gaming, to big-time success. Overall, this cheery slot packs a punch full of intriguing features and slot mechanics together with an RTP of 95,98% - let’s take a closer look!

About the Bonanza Slot

Surrounded by flourishing greenery and dozens of colourful daisies, there sits an exposed gold mine, the backdrop of the reels. On the left is a cosy wooden hut, radiating with the inviting warmth of light from within. On the right is a robust watermill, harnessing the power of the waterfall cascading over it. An appropriate scenery, given that Bonanza was also an early adopter of cascading reels!

Bonanza has six reels and a fluctuating number of rows, with one additional row placed above the reels. The latter functions as a tunnel for Carts, which haul precious symbols, Wilds and Scatters, across four of the reels. The slot features 10 paying symbols and a whopping 117649 paylines, the unprecedented Megaways to win! On top of that, you can look forward to the Wild, Scatter, and the elusive bars of G-O-L-D!

The gameplay of Bonanza is accompanied by a brisk western tune, creating an atmosphere reminiscent of the 19th century California Gold Rush. Every explosive win is followed by raining coins of gold and the ever pleasant Ka-ching! The upbeat sound effects build suspense with every spin; pressing the “Play” button feels like pulling a lever to bring up the treasure-laden carts, you will find yourself eagerly awaiting the outcome of the next roll!

The graphics and animations of the Bonanza online casino slot are quite distinct and captivating, particularly in the background scenery. The artists behind this title were very attentive and took great care of every element of the landscape. From the serene waterfall to the delicate flowers and shrubbery - each bit is detailed and aesthetically pleasing. Some of the animations, particularly the rocky reels, can feel clunky in comparison to the smooth flowing water just outside. In a way, such a stark contrast genuinely captures the underlying ambience of the era. Bonanza has a lot to offer, take a glance at the rules below to familiarise with the inner workings of this intricate title.


At first glance, Bonanza may strike you as somewhat complicated, but at the core, the mechanics are similar to many of the blockbuster online casino games. The Bonanza online casino slot is available both on desktop and mobile platforms of EnergyCasino.


Bonanza features a familiar set of 10 symbols: 9, 10, J, Q, K, A, and four lustrous gemstones in green, blue, red, and purple. Winning combinations can be triggered in groups of three to six, except for the most valuable symbol of the game, the purple jewel, which counts in groups of two to six. Additionally, Bonanza has Wild and Scatter symbols.

Dynamic Rows and Cascading Reels

The Bonanza online slot has six fixed reels, but the number of rows in the reels changes with every spin. Each reel can display anywhere from two to seven symbols. The reels of Bonanza are cascading, meaning that each time you hit a winning combination, all symbols of that combo will disappear from the reel (including all duplicates on reels affected by the winning sequence), and new symbols from above will replace the missing ones, like a chain reaction! This will continue until no winning lines are available.


Mining Carts are one of the unique features of Bonanza, they take up an entire additional horizontal row above the reels, and stretch over the four central reels (reels two, three, four, and five). All symbols that arrive inside the carts adhere to the same paytable; they can help in activating some of the paylines! Some symbols, like the Wild or Scatters during a Free Spin round, can only appear in carts. Each spin will prompt new carts to arrive, and if a cart symbol is part of a winning combo, it will be replaced from right to left by the following carts.


A detailed payout table can be found in the “Settings” menu, on the bottom left of the user interface. The minimum stake is €.20, and the max is €20.00. If you’re lucky enough to hit a combo of six purple gemstones, you’ll be rewarded with 50x your wager! Winning sequences, except Scatter combos, are attributed from left to right. There are a total of 117649 possible paylines.


The Wild of Bonanza is quite appropriate for the gold rush ambience - three lit sticks of dynamite. The Wild can only arrive inside one of the carts in the topmost row and will replace any other symbol in the game, except Scatters.


The Scatter symbols in Bonanza are gold bars that occasionally drop down onto the reels. Each bar is labelled with a G, O, L, D, or +5. If you are lucky enough to land on all four GOLD bars, you will be rewarded with 12 Free Spins. Any additional Scatter on the same spin will award five extra Free Spins. Scatter symbols can land on any reel and do not have to fill the leftmost reel in order to count.

Free Spins Bonus Game

If you are one of the lucky players who hit all four G-O-L-D bars at once, you will get 12 Free Spins and will proceed to the Free Spins Bonus Game. The last bet you placed will be used as the baseline amount for the 12 spins. During this round, there is a special unlimited multiplier active. The multiplier starts at one and will be increased by one for every winning combo. The multiplier does not reset on losing spins. In this mode, the carts can carry special Scatter symbols. These Scatters are depicted as a stack of gold bars, and can only be found in the carts. Landing on three of these Scatters will add five more Free Spins. Four Scatters will award an additional 10 Free Spins. Your winnings will be displayed on the bottom right for the duration of the round, and the total amount will be credited to your account when the round concludes.

Slot Bonanza Jackpot

Bonanza has a chance to be very rewarding, with up to 117649 Megaways to win, but there is no progressive jackpot. There are no multipliers present outside of the Free Spins round, and all winnings during the regular game mode adhere to the paytable.
