Bonanza Slot Machine Graphics & Sound

Bonanza is definitely an accurate name for this slot game with its rural and mining theme. The background transports you to a charming woodland forest with its green grass encompassing the rocky environment. This wonderful scene features a wooden cottage at the left side of the screen and a constantly flowing water wheel to the right where you have all the options you can select to play, change the betting options and view the menu. The reels resemble stone boulders which move with every spin and at the top there is moving cart like something out of the Stone Age featuring some of the symbols found on the 6 reels. This aesthetically pleasing 3D slot has great graphics and has a soothing background score featuring banjos with a faint hint of the Bonanza TV show’s hit theme song. The sound effects certainly compliment the gold mine backdrop.

Bonanza Slot RTP & Variance

With Slot Bonanza’s abundant megaways to win, you are sure to dig up some gold. In a single spin, you can get a maximum payout of 10,000 times your chosen bet. The free spins are certainly rewarding because of the Unlimited Win Multiplier and what’s more, the Return To Player is at 96% which is pretty high. To avoid disappointment, keep in mind that this slot game is a medium volatility one which means, you can sometimes generate small wins or win big a little less often.

Bonanza Slot Bonuses & Symbols

Bonanza slot has a generous variety of colourful symbols. There are the low value symbols which are common in many slots, these being 9, 10, J, Q, K all ranging in payouts between getting 3 and 6 of the same symbols. Their value starts from 0.1 and reaches 1.75 as the highest. The next batch of symbols are the A and other precious gemstones which are Emerald, Sapphire and Ruby. The symbol with the highest value is the diamond which can reward you up to 50 when getting a combination of 6 of them.

The special symbols in this online video slot are the Scatter and Wild. The Wild symbol is a pack of burning red hot dynamite that can replace all symbols except for the scatter. The Scatter symbol is represented as gold bars with the letters of the world GOLD written on them. Whenever your reel lands on all four symbols, this can trigger a free spins round which changes the background to resemble the interior of a mine as the background changes to red and orange, and the reels are now black rocks. When you get the scatter symbols, this triggers up to 12 free spins which are automatically spun.

The carts feature shows a mix of the game’s symbols which can create more frequent wins as well as bigger payouts. Another great feature of the megaways is that if there is a win in the reels, the symbols explode to give way to the new set of symbols. This can happen on both the six reels, as well as on the carts which can create more opportunities for multiple wins at one go. When signing up with an online casino, a welcome bonus is usually included and sometimes there is an allocated number of free spins too. However, you should get a bonus which offers 100% and generous match bonuses when depositing as well as remember to be cautious about the wagering requirements to claim any bonus.
