Bonanza Free Spins: Best USA Bonus Offers

Big Time Gaming is one of the biggest names in online casino gaming - and the much-celebrated inventor of the popular Megaways progressive jackpot.

Bonanza, a six-reel slot that has been on the market since 2016, is one of the many games on the market today that's based around mining for gems and other treasures. It's also the subject of today's review, in which, we will examine everything that this interesting title has to offer.

The main goal of this Bonanza review is to introduce you to all the free spins offers that we can find to use on Bonanza. We'll also list the casino operators that support the best Bonanza deals, whether that's a deposit bonus or something a little more unusual.

As more and more casinos take advantage of the internet's enormous reach, the number of these sites that reward their players - new and old - with bonuses and free spins should begin to increase, too. So, let's start digging.

The Bonanza Slot

You're not going to find a better repository of casino reviews and free spins offered online than right here.

CasinoSmash has many years' worth of experience in the industry, as well as a staff background that includes some of the biggest names in real-money gambling. Think Oddschecker, WhoScored, and respected companies like that. Our first duty is, of course, to our readers, their bankrolls, and their expectations for a fun casino experience.

Perhaps Bonanza isn't as well-known as some of the other games we've reviewed so far, such as Dead or Alive, Starburst, and Blood Suckers.

However, any casino that wants to make its catalog of games stand out is likely to feature a vast expanse of slots titles that vary in theme, popularity, and difficulty. Bonanza's relatively low profile has no impact on its fun factor: its beautiful, fantasy-style graphics are supported by plenty of great features.

To discover our unbiased opinion about Bonanza, keep reading. As a brief introduction, though, Bonanza uses the Megaways feature, as well as Big Time Gaming's "world-first innovation" DUELREACTION, which is a novel take on the cascading reels gimmick that's so popular with modern developers. Oddly enough, it's also Twitch-ready, an obvious boon for casino streamers.

Online Slot Info Sheet

Need a quick rundown of Big Time Gaming's Bonanza? Here's all the important information laid out in an easy-to-digest format. The vast majority of these elements will remain the same from one online casino to the next. Of course, if a website doesn't offer a mobile app, you're unlikely to find Bonanza playable on the go.

Game Theme

Mining has long served as the perfect setting for slots games. Prospecting for gold is a bit of a metaphor for casino gaming, after all.

However, while this game is full of stone, old shacks, and shiny jewels, the game provider actually describes it as a Wild West slot with theme-adherent reels. This marks it out as a bit of an outlier in the developer's wider games collection, as Bonanza is the only title inspired by the Wild West.

Bonanza's soundtrack reinforces this setting by including the slide guitars of dusty, Deep South homesteads.

It's a welcome alternative to the sometimes forgettable ambiance of other casino slots but, as it only plays when the reels spin, it can feel a little intrusive during long play sessions.

Fortunately, there are several tracks on the playlist, including something that sounds like She'll Be Coming 'round the Mountain when She Comes (yee-haw).

As mentioned, Bonanza's major claim to fame comes from the fact that it's built on the Megaways engine. This means that there can be up to 117,649 different ways to win, depending on what symbols the reels throw up.

The DUELREACTION mechanic is an advancement on Megaways, allowing the reels to change horizontally, as well as vertically.

How to Play the Bonanza Slot

It's easy to get overwhelmed by the promise of special features, bonus rounds, free spins, and brand new inventions but, let's be honest, the vast majority of online slots all begin the same way - by hitting the spin button in the middle-bottom of the interface.

Well, here's a surprise for you. In Bonanza, that essential bit of the game lies in the bottom right, along with the auto-spin function.

The players' only other objective is to match up winning combinations of symbols, the appearance and value of which we'll come to next in this review.

Base Game Symbols

As far as the basic symbols are concerned, there's nothing too exciting about Bonanza's visual design. Yes, everybody likes virtual gemstones but many of the stops on the game board are from decks of playing cards.

So, you'll be playing with 9, 10, J, Q, K, and A, and four other symbols in the form of colored jewels, namely, emerald (green), sapphire (blue), ruby (red), and a diamond (also blue).

The value of each of these symbols varies with the number that appears on the game board. For instance, with a 0.10 wager, a green gem is worth multiples of 25. This is expressed as 0.25, 0.50, 0.75, and 2.00 for 3, 4, 5, and 6 jewels, respectively. As you might have worked out by now, the 9 is the lowest value stop, at 0.10 for 3 gems, while the diamond is worth between 5.00 and 50.00.

Bonus Symbols and Features

In keeping with the overall theme, Bonanza's Wild card is a stick of dynamite, while letters that spell out the word GOLD are the slot's scatter symbols. These are involved in triggering the Bonanza free spins feature. Big Time Gaming has also added an Unlimited Win feature. Let's break all that down.

Wild symbols in Bonanza act like any other Wild symbol at online casinos, helping players create winning lines by substituting for any other picture or number.

Scatters, on the other hand, provides 12 free spins when GOLD is spelled out across the reels. During the free spins round that follows, the reels can expand from 5x3 to 6x4, while an additional scatter symbol (+5) increases the number of possible free spins that the player can collect.

As far as Unlimited Wins is concerned, this is a feature of the main game, rather than a bonus round. When payouts are made, the symbols involved explode, revealing new pictures and increasing the active multiplier.

Volatility Level and RTP

The Bonanza slot has an average Return to Player value of 96.00%. This means that, over millions of theoretical spins, players can expect to have 0.96c returned from a wager of $1.

Volatility in Bonanza, a term that describes how much and how often a game pays out, is high. Note that some reviewers seem to disagree with the latter, suggesting medium-high volatility, instead.

Bonanza Megaways vs Bonanza Megapays: What Changes?

Here is where the influence of the innovative game developers is felt the strongest. Bonanza, like fellow BTG slots Who Wants to Be a Millionaire? Kingmaker, Lucky Streak, and Gold are split up into a number of different packages, in this case: two. These are Bonanza Megaways and Bonanza Megapays.

What's the difference? Other than rhyming, Megapays is another plug-and-play slots feature that offers a huge jackpot among other bonuses and promotions. In addition, Bonanza Megapays is backed by a community-derived progressive prize of up to x3,000,000. Most significantly, this jackpot can be won with a minimum bet.

Bonanza Megaways, in comparison, is a reel randomizer. This means that the number and type of symbols that can appear on a reel change with each spin.

What US Casinos Offer Bonanza Slots?

As a quick primer, here are the top casinos that carry Big Time Gaming's Bonanza slot in the United States:

Of these, it's easy to recommend Harrah's casino as the best place to play Bonanza, simply because of its association with Caesar's and its Rewards loyalty scheme.

Winner of USA Today's Best Players' Club award, Caesar's Rewards is a mixture of online and offline perks, fuelled by points that can be earned from slots, video poker, blackjack, and other casino games. In general, points are accrued at a rate of 1 point per $10 spent on slots, though this increases to a maximum of $50/point in blackjack.

Unfortunately, Bonanza Megapays doesn't seem to be present at any of the online casinos we visited, which is a shame. As Bonanza is still the only Big Time Gaming slot to feature this mechanic, though, there's a strong chance that the game's rollout to US operators hasn't yet begun, meaning that it could be only a matter of time before Megapays makes an appearance on these shores.

While not plentiful, Harrah's has a number of unique promotions available to visitors, whether new or returning. These include giveaways on games by particular developers, such as NetEnt, daily jackpots, and a welcome bonus. Of course, as a brick-and-mortar casino, too, it can be a little difficult to find the correct website amid all the company's other properties.

If you bonus are all that matters to you, this guide on how to get 100 free spins on Book of Dead is a precious resource where you find some other incredible offers for players in the United States.

Can I play Bonanza at Online Casinos for Free?

Harrah's does offer a $10 no deposit free spins bonus when new players sign-up for an account. However, withdrawals are covered by wagering requirements and a seven-day usage limit.

The conditions of the offer are buried in the site's terms and conditions, which makes the promotion seem a little undesirable to newcomers.

Casinos like Harrah's can only accept players from certain states, such as New Jersey, but demo plays and other Bonanza free spins are available (or not) on a site-by-site basis. Don't be discouraged if the first casino you stumble across doesn't seem to have the Bonanza slot on its website.
