Big Winner Review & Ratings 2025: Is Big Winner Legit?

Operators like BigWinner sportsbook and online casino are competing with others for customers, so are trying to create the best betting offers online as well as making the best casino bonuses available to new customers. As BigWinner already has a reputation for offering good bonuses, we were keen to see what they had to offer this time, and we weren’t disappointed.

BigWinner sportsbook and online casino have more than one bonus on offer, and although they are similar, we’ll look at them separately. First, we have the regular bonus, which is a no-fuss 100% deposit match up to INR100000 with 10% cashback on losses in the first 7 days. This applies to first deposits over INR500 and looks very generous.

More generous, however, is what they call the high roller bonus, which is a 150% match up to INR200000 with 12% cashback on your first 7 day’s losses. There is also a minimum deposit amount here as well for those who want to take advantage of this boosted offer.

This BigWinner sportsbook and online casino review found no evidence that you will need a BigWinner promo code to claim either offer, so they both qualify as a simple, straightforward bonus to get you started.

BigWinner sportsbook and online casino wagering requirements

All welcome bonuses have wagering requirements, and these are no different. What you need to do here to keep your side of the bargain is a simple 35x playthrough on slots, so you’ll need to save playing table games until after you’ve met those requirements.

35x might seem a bit hefty, and quite daunting to new players (especially for that 150% match), but with the number of slots on offer here (more on that later) and a decent RTP (return to player) percentage, the requirement seems to be well within reach.

One final note here is that in the competitive world of online casinos, these offers can change and improve regularly, so we always recommend that before you sign up yourself, you make sure that you read the terms and conditions to make sure the deal you are getting is the same as the one you are reading about here.

There is one thing that all of the best bookmaker sites have in common, and that is they are straightforward to use and easy to navigate. So, while BigWinner sportsbook and online casino is unlikely to win plaudits from the people that hand out awards, the easy-to-use layout will be welcome to all customers, and has no loading issues or lagging.

First-timers will not be intimidated by what they see (despite the enormous amount of choice on offer) and more experienced users will find this a welcome change and take to it immediately. The simple and patriotic colour scheme is easy on the eye, making the game tiles stand out so you can see exactly what is on offer.

Finding the games you want

With this many games on offer, you might expect finding what you want to be a real chore, but that’s not the case here at all. You can sort through the games on display using tabs at the top to sort by slots and tables games, as well as by the different types on offer. This range will be covered in more detail in its own dedicated section later on, but the short version is that nobody is going to get lost while looking for something to play.

Navigating around the site

The next thing this BigWinner sportsbook and online casino review needed to look at was the basic admin of the account, and how you might find your way around the various screens to find the important things like your account details and payment options, as well as links to getting help if you needed it. We are pleased to report that, even if you have never used an online casino before, you have no trouble with any of these tasks as navigation is intuitive, and the key areas are exactly where you expect them to be.

Using BigWinner sportsbook and online casino on mobile devices

In this day and age, as many people are likely going to be using BigWinner sportsbook and online casino on their mobile devices as they are on desktops. When we tried it on phone and tablet we found it simple, although there was quite a lot of scrolling to do.

One improvement that BigWinner can make is to develop an app that makes mobile playing easier, although you can still have a good experience with how things are now.

Big players in the online betting world like Bet365 casino are renowned for offering plenty of payment options for customers, and BigWinner is looking to join that elite club with a huge number of choices for funding your account.

When it comes to making payments, as you might expect, bank transfers via Trustly lead the way, with Visa and Mastercard not far behind. However, if these aren’t right for you, also have the choice of Skrill, Neteller, or MuchBetter, as well as Paysafecard, AstroPay Card, EcoPayz, iDebit, and InstaDebit. These deposit methods are all quite rapid, and with that much choice, customers would be hard-pressed not to find a way to get the ball rolling. It should also be mentioned that the operator does reserve the right to refuse any transactions or make an additional charge if they deem it necessary.

Making withdrawals at BigWinner online sportsbook and casino

Withdrawals can take place once you have met all of the wagering conditions of the bonus and have completed any ID check requirements needed. You can then withdraw using Trustly, Visa, and Mastercard or one of the other methods like Skrill, Neteller, EcoPayz, Paysafecard, AstroPay Card, InstaDebit, or iDebit. Bank wire transfer is also available, but there is currently no option for a cheque in the post.

Withdrawal times vary and are subject to a 72-hour processing delay. After that e-wallets like Skrill should clear in under two hours, with other methods like bank transfers and cards taking 1-7 days depending on who your account happens to be with. Withdrawals are also limited to a maximum of INR 500000 per week.

Next on the list of the things this BigWinner sportsbook and online casino review needs to look at in detail, are the customer support options. While we have found everything that we have looked at so far to be excellent, there are always some areas of an operation that are better than others. While we would not consider customer support to be the ‘Achilles heel’ of BigWinner, it certainly could do with a little work.

What is there, however, is definitely fit for purpose. The FAQ section will help out newbies with basic problems but is a little generic, and the online form for raising a query gives you plenty of scope for describing your problem in detail, but it’s what is not there that is the issue.

We would have expected to see a live chat option, as well as either text or phone support to get full marks in this area, but they are conspicuous by their absence. We can only hope that the forthcoming changes that will bring the BigWinner online sportsbook online, will also include upgrades for the customer service options too. So, overall while what is there is not awful, it is not quite up to the standards BigWinner displays elsewhere.

One area where BigWinner does excel though is with its licensing and security. When sharing your data and your money with an online casino and sportsbook, you are going to want to know that you can trust them, and this BigWinner sportsbook and online casino review can report that everything here gets the seal of approval from us.

BigWinner is regulated by the Government of Gibraltar Licensing Authority and is owned and operated by Markor Technology Limited, which is quite a large operation but is yet to be listed on the stock exchange. The site has no other certifications but operates account verification so that no minors can play on the site, and also geolocation so that people from prohibited territories have no visibility of what is on offer.

In addition to this, the padlock symbol in the address bar is a sure sign that SSL encryption is in play, and all of your transactions will be secure and kept private. So overall, we are very pleased with what BigWinner has to offer in this area.

Another area where BigWinner excels is with the loyalty program. Like many other online casinos, BigWinner has a loyalty program where players earn rewards by playing the various games on offer here. The program has four tiers, bronze, silver, gold, and diamond, and where you are on the program will dictate the number of bonus spins and amount of cashback you are likely to get when cashing in those points.

There are other awards for regular players, including some free spins for validating your email address, as well as various drop and wins and cash prizes for those that top the leaderboards on the monthly competitions. Clearly, these features favour regular players, but more casual players can see what they get when they cash out their points at the end of each day’s play.
