Big Time Gaming's Bonanza online slot is a Megaways game that offers you over 100,000 winning ways.

It features the Duelreation cascading reel system that allows the reels to cascade in both directions, which works really well with the Megaways feature.

It is a popular game amongst online slots players around the world thanks to its unique format and bonus features.

Graphics and Theme

The game has a Wild West / Gold Mining / Jewels theme. The fast pace of te game and foot-tapping music work really well with the themes and graphics are beautifully presented.  

When you enter the game, you'll be whisked off to a beautiful Western mountain landscape, where the mining takes place.

With green grass and a rocky environment, it's filled with flowers and character. There's a wood cabin to the side of the screen, and an animated water wheel running constantly. The perfect setting for a classic online slot.

How To Play Bonanza Slot

Quick guide to help you get started:

  1. Click the list menu to check out the paytable and select your sound preferences
  2. Adjust your total bet using the < & > buttons
  3. Fix a session budget, hit the spin button

Upon first glance, BTG's Bonanza slot seems a pretty complex slot. After all, it has six reels rather than five, and there is a different number of symbols on the reels every spin. However, you'll be pleased to know that playing Bonanza is quite simple.

Each reel can show between 2 symbols and 7 symbols, and there's a set of small reels along the top of the screen. Since each reel shows a different number of symbols, the total number of winning ways varies with each spin.

This is how the Megaways mechanic works, and you'll see it in plenty of Big Time Gaming slots.

Bonanza Game Payouts

To hit a winning combination while playing the slot Bonanza, you have to land three or more matching symbols on adjacent paylines. This differs from payline-based games, as if offers up more winning potential overall.

Overall Review

Big Time Gaming's Bonanza is filled with adventure from start to finish. The concept is unique and entertaining, and the music gives the game a light-hearted feel. 

There's a reason why Bonanza has prevailed as one of the most popular Megaways games of all time. Even as dozens of new Megaways slots are released, Bonanza maintains its position at the top of many slot fans' to-play list.

This is because Bonanza originated all of the features that players have come to associate with Megaways slots. The cascading reels paired with free spins that feature increasing multipliers set the standard. Even though there are now dozens of slots that come with this same format, most players prefer the original.

The graphics look real, and it takes you to a charming place with the animations being a bonus we welcome. The underground feature is the best by far.
