Three reasons we had to write this WinBonanza review
We’re always looking for new sweepstakes casinos to review, but we were especially excited to test WinBonanza. Here’s why:
1. Generous free welcome package
The WinBonanza bonus that every new player can claim when registering with our link includes up to 50,000 Gold Coins and 5 Sweeps Coins. There’s no better way to get started at this sweepstakes casino in our opinion. But to claim the full bonus, you’ll need to complete a series of tasks. Here’s what is required:
-
Create an account and verify your email
-
Confirm your telephone number
-
Allow email updates
-
Allow text updates
-
Claim your first daily login bonus
As you complete each of these five requirements, you’ll receive 10,000 Gold Coins and 1 free Sweeps Coin per task. The bonus also provides 20 free spins to use on Devil’s Bonanza Twins by Jili, which is one of the site’s most popular sweepstakes slot games.
2. WinBonanza has multiple sister sites
Before starting this WinBonanza review, we scrolled to the website footer to see what information was available. It was here that we found WinBonanza is a sister site of Zula Casino, Sportzino, Yay! Casino, Fortune Coins, American Luck, and Luck Party. We’ve reviewed many of these sweepstakes casinos before, with each brand providing an impressive user experience.
3. Trusted software providers
This sweepstakes casino includes more than 500 casino-style games from software providers like Jili, Relax Gaming, Mascot Gaming, Booming Games, Edge Labs, and more. You may notice some of these providers from our recent Elevyn review, and that’s because they’re some of the industry’s best. Not only do they ensure high production standards, but you can also expect certified RNGs (Random Number Generators) to ensure fairness.
What are the differences between Gold Coins and Sweeps Coins?
You will have noticed we’ve mentioned Gold Coins and Sweeps Coins already during this WinBonanza review. They’re at the heart of this sweepstakes casino since they can be used to play casino-style games. Here’s a quick summary of the differences:
- Gold Coins can be obtained via promotions or voluntary GC purchases. They can be used to play casino-style games in standard mode, but have no monetary value or use beyond gameplay.
- Sweeps Coins must be obtained exclusively via promotions. They are used to play casino-style games in sweepstakes mode, where SC winnings are redeemable for prizes.
Sound familiar? That’s because it’s an identical setup to what we noted in the Spinsly review and at many other sweepstakes casinos. Just keep in mind there are several requirements of SC redemptions, including ID verification, playthroughs, and minimum redemption thresholds.
Is WinBonanza legit? Here’s how we know this brand is safe
WinBonanza is a legitimate sweepstakes casino site available in 35 US states, provided you are at least 18 years old. The brand is also owned by SGSE LLC, an American company headquartered in Delaware with a long track record of popular sweepstakes casinos. There’s even mandatory KYC (Know Your Customer), so everything is done above board here.
The advanced SSL encryption software used by the site also gave us a lot of confidence while creating this WinBonanza review. It was also encouraging to see player control tools such as GC purchase limits and timeouts.
Why we loved the sweepstakes slot collection at WinBonanza Casino
One thing we noticed with this sweepstakes casino is that slot games are the dominant category, similar to the Sweepolis review. These casino-style games can be played on any modern device, including computers, tablets, and mobile phones. And with over 500 titles on offer, you’ll have plenty to keep you entertained.
Naturally, since the game library is so large, you can expect a variety of themes and features. For instance, games like Diamond Hits and Joker’s Fortune are perfect if you love classic sweepstakes slots with traditional fruit machine symbols. If you prefer a more modern approach to gaming, then check out hold & win slots like Aztec Fire 2, Coin Tornado, or Diamonds of Liberty.
Exclusive sweepstakes slot: Riot Feral Riches
We noticed there were a few sweepstakes slot games labelled with an ‘Exclusive’ banner, which was great to see. Exclusive titles are important, as they ensure there’s something new for even the most experienced of sweepstakes casino players to experience. Our favorite exclusive slot throughout this WinBonanza Casino review had to be Riot Feral Riches by Mascot Gaming.
This sweepstakes slot featured a 5-reel, 3-row layout with high volatility, a max win of 2,500x, and a competitive RTP (Return to Player) of 96.16%. The game wasn’t lacking in engaging gameplay features either. When spinning these reels, you can expect free spins, a hold-and-win bonus feature, plus four jackpot prizes, including Mini, Minor, Major, and Grand.
Simple navigation and unique game categories
If you thought the Amazon Jackpots review did a good job of showcasing a brand with efficient navigation, WinBonanza takes things to a new level. Of course, the website’s main navigation menu provides clear access to core pages such as promotions, games, support, and account management. But it’s the games lobby where things get really interesting.
In the lobby, we found unique filters such as “Bonanza’s Picks” and “Provider of the Week”. You don’t see this too often at competing sites, so it’s certainly something different. At the time of writing, the provider of the week category showcased the top games from Kalamba, but this is updated with a new provider every 7 days.
How well does WinBonanza work on mobile?
If you’re someone who prefers to play sweepstakes casinos on mobile, then all of the same navigational features and benefits can be found on your smartphone. We tested the mobile performance extensively in this WinBonanza review and found zero red flags. Games load quickly, play smoothly, and every touch target is responsive. Sure, there might not be a native app, but you can also save a link to the WinBonanza homepage on your phone’s home screen to mirror the one-tap access of an app.
Why are payments relevant to the WinBonanza sweepstakes casino?
Now, we know what you’re thinking: why are payment methods needed at WinBonanza when sweepstakes casinos are free to play? Well, there are two main reasons, including voluntary Gold Coin purchases and Sweeps Coin redemptions. Let’s take a closer look at each:
💰 Voluntary Gold Coin purchases
Gold Coin purchases are not required to play at WinBonanza since there’s such a fantastic list of free promotions. But there’s no denying it’s an easy way to increase your balance, especially as a new player since an additional welcome bonus is available. You can pick from the following three boosted GC bundles:
- 250,000 GC for $2.99, plus 10 free SC
- 950,000 GC for $9.99, plus 25 free SC
- 1,500,000 GC for $14.99, plus 37 free SC
If you choose to make your first voluntary Gold Coins purchase, you can make the payment using Visa or Mastercard. With either payment method, you can expect instant, fee-free transactions.
🏆 Redeeming Sweeps Coins for prizes
Before you can even access WinBonanza redemptions, you must have an ID-verified account. The review process typically takes between 3 and 7 business days, so we recommend submitting copies of the required documents immediately after registration to avoid delays. After verification, you must accumulate at least 50 Sweeps Coins that have been played twice each to request a cash prize.
You can have this processed via an ACH bank transfer, typically within 3–10 business days.
Can you count on the WinBonanza support services?
The support services that we found in this WinBonanza review include a dedicated help center with FAQs, email support, and a ticketing system. Honestly, an easy upgrade for this sweepstakes casino would be to add a live chat. That said, the current support methods are still delivered to a high standard.
With this in mind, the perfect starting point is usually the help center. Here, you can find instant solutions to the platform’s most common issues, including verification, payments, promotions, and more. If you can’t find a solution here, you can either open a ticket or send an email to the team. They’ll typically respond in 12 hours or less and can provide solutions to any problem you might be facing. We spoke with several support agents via email, and they were always friendly, happy to help, and knowledgeable.
