This game proves you don’t have to endlessly dig underground to uncover a wealth of precious gems
The gold-mining themed slot offers impressive graphics and a fun premise, but make no mistake: the gameplay is at the heart of Bonanza's success.

With its 10,000x jackpot, Bonanza slot is available to play at Mr Green online casino on both desktop and mobile devices.

How to Play Bonanza slot online

The reels sit in front of a mine, with a stunning waterfall and a miner’s cabin surrounding it. You’ll need to prepare your carts, seeing as numerous Emeralds, Sapphires, Rubies, and Diamonds will land during each spin. So be prepared to dig, and dig deep.

There are a total of 15 symbols in the Bonanza slot: 10 standard symbols, 4 scatters, and 1 wild. As typical of slots, lower-value symbols are represented by standard playing cards. In a fashion that's also familiar with most slots, the first six symbols are 9, 10, J, Q, K, and A. In line with the mining theme, the diamond cut is the highest-paying symbol, with the next three resembling uncut green, blue, and red diamonds.

Scatters are shown as Golden Bars, and once you have three or more on the reels, they’ll activate the Free Spins round. The Wild is the Explosive, which substitutes for any symbol except Scatters. Any time a Wild is a part of a winning combination, it creates one hell of an explosion (warning: get your earplugs ready).

The six reels aside, there’s a horizontal reel that comes out of the mine on four carts that carry four extra symbols. All of these symbols can be included in winning combinations on the reels below them.

All winning symbols explode, which makes way for additional symbols to appear. This creates an opportunity for even more wins in that very same spin. The list of options and settings is pretty basic, limited to the Paytables, Stake, Autoplay, and Spin button.

Graphics and Sounds

The graphics are incredibly realistic and set the scene for an exciting Gold Rush adventure. Bonanza starts in a remote woodland area with an old cottage that features a stream running right next to it. That might sound like the slot offers a calming experience, but it would be a mistake to expect anything remotely calming in this game. As you progress on your journey, you’ll go deep underground to find treasure in the mines, where you won't find a moment's peace.

The developer clearly decided to invest their best resources in stunning graphics, which is one of the best features of the game. Both the background and symbols display impressive animation and beautiful colours designed to keep you entertained for an entire day’s play. You'll be wanting to play the next day too, as this kind of design entices you to play again and again.


For many players, the Megaways game engine is the most exciting aspect of the slot. After all, Megaways has changed the online slots industry, and Bonanza is one of the most popular Megaways slots around. The number of ways you can win changes with each spin of the reels. If symbols are covering all reels, there are up to 117,649 ways to win, which is pretty incredible.

The special top row is partly responsible for creating an enormous amount of winning combinations. It might seem somewhat difficult to get to grips with at first but essentially wins are awarded from left to right, with adjacent symbols paying out for all symbol sizes, as long as there are three or more matching symbols on a pay line. You can get away with just two symbols if it’s the purple diamond, as it’s the highest-value symbol.

In-game Bonus Features

Cascading Reels

The cascading reels are a well-known feature in many slots, but in Bonanza, it stands out based on their frequency. The mechanics ensure that winning combinations disappear to make way for additional symbols. In the event of another winning combination being formed, the feature repeats. This is a great way for wins to build up. Along with the Dual Reaction feature, where additional symbols roll in from carts and form winning combinations, there's some big win potential here.

Free Spins

Bonanza offers a truly impressive free spins feature. The aptly named G, O, L, and D symbols activate 12 free spins when they appear on the reels. Scatters in the top cart can reactivate at least five spins, with no limit on the number of times this can be reactivated. Not only that but each time you land a winning combination during free spins round, the multiplier with each win increases by one. This is also unlimited, so in theory, you can enjoy a constantly increasing multiplier, and with cascading reels, also build the multiplier. This can jump up a few spots on a single spin for a chance to land some pretty huge wins.

The only thing you need to do to be rewarded with free spins is to play. Once four scatters appear on the reels, you’ll receive 12 free spins. Each scatters will award you 5 additional spins. When activated, the reels and the background turn red, indicating something major is just around the corner.

How to win

With so many rocks heading your way, you’ll discover numerous precious stones, as you spin the enormous slot machine (we're talking more than five reels here). A six-figure payline count is realistic, and there’s even the possibility of seven rows of symbols. The carts add an additional symbol to each of the reels, which creates more variety to the potential winning combinations. Each winning combination explodes, after which the symbols drop in from above to present you with a fresh opportunity to play and win.

There are five purple gemstone symbols in the base game that provide a 50x stake. When the free spins feature is activated and multipliers are taken into account, however, that stake can increase significantly.
