Design, Theme and Visuals

bonanza megaways base game

With a mining theme, the Bonanza Megaways slot might not quite have the visual flair of some more modern Megaways titles but the design in this mining extravaganza is more than up to the job.

Released in December 2016, the up-tempo, Hillbilly-style soundtrack is a perfect fit for the theme and is a major factor of its popularity. A rocky mine is the setting.

On the reels are A to 9 royals which appear alongside 4 more rewarding gemstone symbols. The highest paying symbol is the purple gem. Land a combination of 6 purple stones on adjacent reels and you can look forward to a payout of 50 x your total bet.

The sticks of dynamite symbol is the wild. This can appear on the top window on the middle 4 reels. This replaces all the standard symbols when it makes up part of a winning combination. The scatter is slightly unusual. The letters that make up the word GOLD are all scatters. Land the whole word and you’ll trigger the Free Spins feature which we’ll look at in detailed below.

The Bonanza Megaways slot is played using a 6 reel machine and the Megaways engine. The number of symbols that appear on each reel changes with each spin. The more symbols on display, the more opportunities you’ll have to create a winning combination. If all the reels contain the maximum number of symbols, you’ll have 117,649 Megaways in play.

Winning combinations here are formed by landing 3 or more matching symbols or wilds on adjoining reels from left to right, starting from the leftmost reel. Symbols don’t necessarily have to be next to each other, anywhere on the reel will do.

You can try and mine a bumper payout here at bet levels that range from between .20 cents to $40 per spin. Use the arrows below the stake box to adjust your bet size. Click on the settings to open up the paytable. Payout amounts are shown as multiples of your total bet. It’s all nice and easy to follow.

You will also find an Auto function which allows up to 100 autospins. Then you can set loss and single win limits. Any trigger of the Free Spins feature will stop the autospins immediately.

The Bonanza Megaways RTP is 96% which is about average for an online slot game. The volatility here is in the medium to high range and ranked by developer Big Time Gaming as 3/5.

The maximum win is 12,000 x your total bet per spin. Whilst this can be won on any spin, including the base game, your chances increase during the free spins due to the unlimited win multiplier (more details below).

Bonus Features

With 3 bonus features, reaction wins and free spins with increasing multiplier are the key feature elements on offer in the Bonanza Megaways slot. Let’s dig a little deeper.

Reactions feature

Whenever you land a winning combination, the Reaction feature is triggered and a reaction takes place. The successful symbols are blasted off the reels and new symbols drop into the vacated positions and replace them. A new payout consideration then follows with the new positions in place.

If a new winning combination is formed, a new reaction follows and the process is repeated. This can lead to wave after wave of winners being created from a single spin. These reaction wins can be even more lucrative when you land them during the free spins as you’ll discover below.

Free Spins feature

This main extra, the Free Spins feature, in Bonanza Megaways activated by landing scatter symbols that spell out the word GOLD. You’ll then go on to play 12 free spins. If you’re lucky enough to land any more scatters on the triggering spin, each one adds another 5 free spins to your haul. If you were to land 6 scatters for example, you’d begin with 22 free spins.

The Reactions feature during the free spins are even more valuable than during the base game. The free spins begins with a standard 1x multiplier active. Each time you land a ‘reaction’ win, that multiplier increases by 1.

This is known as the Unlimited Win Multiplier feature. What makes this so potentially rewarding is that the multiplier does not reset following an unsuccessful spin or reaction. It can keep on rising throughout the free spins.

Hope to see trolleys of gold bars trundle onto the reels too as they can deliver retriggers with 5 or 10 more free spins being added to your current total. There’s no limit to the number of potential retriggers, nor the maximum size of the multiplier. Get on a roll here and some explosive action is possible.
