How to Play Bonanza Slot Online

Set in an American mining village, this cartoon style slot has pretty graphics. Simplistic, but less is more when it comes to the presentation of BONANZA slot game. The narrative takes place in locations relevant to a mining village. This includes grassy hills, flowery boulders, mining tunnels and the prospector's hut. To start playing the game on Easy Slots Casino, it is important to first understand its underlying mechanisms:

  1. The 6-reel slot uses the Megaways mechanism system, allowing the reels to feature 2 to 7 symbols; this number adjusts according to the rows, which randomly expand from 2 – 7. As a result, the number of winning ways varies greatly, with a maximum of 117,649 on each spin.
  2. To start the Bonanza slot game, players must first set their stakes per spin, which range from £0.20 - £20. This range is amongst the most generous compared to other Megaways slots that offer up to £10 per spin value.
  3. After you hit the spin button, or employ the Autoplay function, you can land winning combinations by landing 3 identical symbols on adjacent reels. When this happens, the winning symbols will explode from the reels, to be instantlyreplaced by new symbols from the skies of the Bonanza reels. This will continue until there are no more winning combinations available.

The above is the gameplay process of Bonanza in a nutshell. There are instances where you can land wins with 2 adjacent high paying symbols, or even less when the wilds come into place. More on that below.

Bonanza Free Spins & Bonus Features

One thing is for sure. Bonanza wouldn’t be the hit that it is in 2021, if it weren’t for the explosive gaming experience that the combination of its bonus features provide.

Wild Symbols

Above the game grid, there is an extra row with four slots. This is the only area that the Bonanza wild symbols can land, both during the base and the bonus game. The wild in Bonanza slot is the dynamite sticks, which can replace all other symbols, other than the scatter symbol. This transformation will help form winning combinations.

Reactions feature

First off, it is important to state that not all Megaways slot games employ the cascading reels feature that we touched upon in the Bonanza gameplay part. Named ‘Reactions Feature’, this is the mechanic responsible for the vanishing of winning symbols from Bonanza reels. As a result, players can continue winning at Bonanza without paying for a new spin. Further, the Megaways element means that if you land a winning combination at a spin with over 50,000 winning ways, there could come follow-up wins with spectacularly large sums.

Unlimited Free Spins feature

If you have ever played Bonanza before, you must have noticed the G, O, L, D letters; these are the scatter symbols, and if you land all 4 of them on the reels, the ‘Free Spins Feature’ will be triggered.

Once activated, you will be awarded 12 free spins, up to 22 free spins for 6 scatters! During your free spins, exploding reels become active and a multiplier is applied to any wins.

Further, the bars of gold will also give you 5 free spins when you land 3 so keep an eye out for these. 

Unlimited Multiplier feature

During the free spins feature of Bonanza, a single multiplier value is applied to all wins. After each explosive reaction, the multiplier value is increasing by 1x up to an unlimited number. Thanks to the multiplier of Bonanza slots, there are great chances to land the maximum win of the game during any free spin – capped at 12,000x your bet level.

Bonanza Slots Game Theme & Symbols

Bonanza slot game offers its players stunning visual compositions. The game is set in an American mining village in the late nineteenth century. The pretty and simplistic illustrations mind us of retro computer games. The locations presented are homely and warm. It made us eager to keep returning to this fun online slot casino game, again and again. We recommend playing this game with two kinds of eyewear.

Firstly, protective goggles, to stop any bits of rock going into your eyes as you spin the Bonanza reels. Secondly, shades to protect your eyes from the bright glimmer of the flawless gems! These gems are designed beautifully, with deep, bold colours of red, blue and green. The coins within the game are also designed to fit the mining theme. These are classical gold, silver and bronze styles of coins. They have an authentic nineteenth-century American design, that is extremely visually appealing.

Symbols on the Bonanza game reels include the lower paying playing card symbols (9, 10, J, Q, K, A). These playing card symbols can pay anything from 0.1 to 1.75 times your current stake for landing 3 to 6 of the same symbol. The diamond, red ruby, blue sapphire and green emeralds are the higher paying symbols. We love the illustrations of these precious gems. They glistened so beautifully we could not help but try to grab them through our device's screen.

The diamond is the highest paying symbol in Bonanza slots, and it will award players with 50 times their current bet level. This is achieved when the player lands 6 diamonds on the reels. At the top of the reels, there are symbols displaying the four additional paying symbols. On every spin, these are added to the reels directly below. This gives you an even higher chance of scoring a winning combination as you play Bonanza Slots.
