Before you go mining for treasure, you should set your bets, and here’s how you can do it:

  • Stake will help you adjust coins size which is essentially makes your total bet.
  • Play will set the reels spinning once you decide on the amount you wish to bet
  • Autoplay is used to set the reels into the automatic motion series for the preset number of times which you choose. 

Slot Features

Now, let’s see what Bonanza slot has to offer to all of us should we decide to take these reels for a spin. This is not a slot which would actually fall under the category of action packed slots, but it still can offer entertainment which will keep you occupied for hours.

The Wild symbol in this game is represented as the dynamite, and it can substitute for any other symbol except for the Scatters. 

Each Mine Cart adds a symbol to the reel and it is set above for reels 2, 3, 4 and 5. Every winning symbol that is a part of reaction and is replaced by symbols coming from above on the reels and from the right in the carts.

During Free Spins you can win an unlimited multiplier which increases after every reaction you create. Free Spin scatters appear only in carts, 3 scatters add 5 extra free spins, 4 scatters add additional 10 extra spins.

Cascade Wins, some nice designs of slots. graphically nice, many different gamble amounts not much more I can list. Good name for the machines?...……..


Where to start, please DO NOT PLAY THESE SLOTS, Why should you listen to me? I have put over 10k into these rubbish machines, you do not win, they take , take and take and the worst thing is, in the industry its the hardest to hit the bonus, so many times I have hit the bonus i.e. tonight of this review and got £4 yes you read it right £4.
Playing this evening the bonuses are useless. You may think this is a rage review but I have been playing these slots for months and pumping money after money in to get nothing! DO NOT PLAY slots from this scam company, read up about them first and stop the stealing your money, unless people stop using these machines they will continue to steal your money. Do not believe this rubbish about them being volatile its made up to lull you into a false security. Take it from a seasoned gambler otherwise you will lose your money.

Like most who got the Bonanza bug, I have a love/hate relationship with this slot by BTG. The first time I ever tried it, I had a balance of a little under $10, I set the bet size to $0.20, tossed it on auto play for 50 round and went to check on dinner. When I returned the game was loaded up on the bonus round and by the time the round was finished I had won a little over 800x my bet which left me with more that 15x my starting balance. Certainly a balance changer, after reviewing the games paytables and discovering that my bonus round wasn't even close to the maximum payout possible it's safe to assume that I kept spinning and trying to achieve higher and higher rewards.

While I did manage to experience the highs brought on by seeing some truly exceptional bonus rounds and massive returns when compared to betsize, I've yet to see anywhere close to the maximum payout of 10,000x betsize, my highest win still remains under 1500x on this game. 1500x is certainly nothing to complain about, but still a far cry from the maximum possible "HUGE HIT" seen in the paytables or in random screenshots posted on various player forums.


Then of course there is the lows to discuss. The 2000-3000 spins without seeing the letters line up to spell gold and bring the player the long overdue bonus round. Sadly when facing such a drought, and hitting that spin button again and again tempting fate and counting the amount of dead spins it takes to finally bring a reward in the form of a massive win in the bonus round, the player is instead left cursing the gods of chance as they see the final result of the long awaited bonus. Yes, not only can the game go thousands and thousands of spins before delivering a bonus round, it can then add insult to injury by paying a soul crushing five times, 3times or to the very unfortunate 1x bet size as a reward for the players persistence and dedication in their hunt for GOLD.

It's player beware when chasing gold in Bonanza, because this game is the epitome of feast or famine.

I've mentioned in this forum about NetEnt sped up some of their games and it felt a bit rushed, it's like having dinner at a restaurant, courses served quickly and the check shoved in front of your face. Playing slots is not only about winning, you have to enjoy it, that's why I don't like fast paced games but there's only 1 games provider that I don't mind their games being fast paced; Big Time Gaming. To be honest, I think their games are designed to be fast paced and therefore the gameplay might feel naturally.

I was introduced to BTG somewhere between late 2015 and early 2016, Gold was the first BTG game I played but back then, I didn't know that Gold was BTG game because I was playing it at a Microgaming casino, so I guess Big Time Gaming has been active for quite some time then. Later on BTG became more popular and more games were released, Dragon Born was my favorite but then came Bonanza. This game has caught my attention for at least a week. First time, beginners luck, I won over €400 with only €0,40 bet. I was stunned and became 'addicted' to it but I was cured after several bad runs. This was literally game of the week or lets just say this was a week game for me.

Bonanza is almost a perfect game, stunning graphics, fluent gameplay, awesome sounds and tracks but aside that, almost unlimited paylines, unlimited multiplier but the most inportant thing why many players love this game is the potential of huge payouts. Most of us might know Thunderkick latest release Pink Elephants that has a max payout of 8600 times bet, I believe Bonanza can top that, haven't seen it yet but I know it's possible.

I have hunted for the ultra win on this game and only managed to hit 2 of them but I will catch the biggest ever some of these days hehehe. So far, the biggest win was over 1600 times bet in the base game, I strongly believe this could also be won in the bonus feature with an active multiplier.

Bonanza is a highly recommended BTG game, in fact, I think this is the game that will become a classic in the future.
