🔔 What constitutes a good bonus and why are these the best casino bonus offers?

At Bigwinboard, we offer a wide range of different casino bonuses from the standard 100% offer to 200% casino bonuses and even higher. Some of the offers found in our list of best casino bonuses are exclusive and cannot be found elsewhere. But should you go for any casino bonus or are there any deal breakers one has to be aware of? While the majority of casino bonuses on offer appear to be more or less the same, they are all unique when laid out in detail. Within their budget, every casino tries to maximize the first deposit bonus in order to attract new players in an industry that involves serious competition. But don't fall for sweet talk. A 500% casino bonus may sound great to you but read the terms before making a decision.

The biggest bonus isn't always the best casino bonus and may have ridiculous requirements attached to it. Larger casino bonuses usually means increased wagering requirements and, in some cases, max withdrawal limits. As a result of changes in the market having a negative impact on the remote gambling industry, coming across quality bonuses is becoming increasingly hard.

🔔 Bigwinboard - An Extra Layer of Protection

The virtual nature of iGaming is often a cause of concern for many players as the authenticity of casinos can be hard to verify. In general, there's rather wide-spread mistrust against online casinos that is often further cemented by the many issues and disputes reported in social media and across forums. For every good casino there seems to be at least 10 bad ones. For the untrained eye, and even for experienced players, it can be hard to differentiate bad casinos from the good. One cannot simply judge the quality of a casino just by the visual appearance and not even a proper license is always enough to ensure you'll have a positive experience. This is where Bigwinboard comes into the picture.

To us, our main priority is to provide our visitors with high-quality casinos. From day one, our policy has been only to promote solid, reputable casinos that offer the best casino bonuses on the market and that meet certain standards and even goes beyond the levels of basic quality that you would typically expect and require. To obtain accreditation status and be allowed a spot on our list of best casino bonus offers there are many things we need to consider. We use our extensive knowledge of the industry and years of collective experience to separate the good from the bad. This is also why we limit ourselves to only a few casinos out of the thousands casinos operating on the market. Here you will only find the best of the best. If you want to know a bit more about what we look for in our casinos, visit our best online casinos page for more information. Moreover, players that sign up to the casinos we promote automatically receive an extra layer of protection, or insurance if you will. As we are in direct contact with the casinos we promote we will gladly help to resolve any issues should they occur.

🔔 Best Casino Bonus & Wagering

New players may be unfamiliar with the concept of wagering and run the risk of falling into a few classic traps. It's quite unusual for online casinos not to attach wagering requirements to their bonus offers. What that means in a few simple words is the amount you need to gamble before your balance is unlocked and a withdrawal can be requested. Some will be annoyed by these requirements, but one has to keep in mind that it's free money offered as an incentive by the casino and, believe it or not, it actually gives you an edge against the casino. If that wasn't the case, casinos would give you bonuses on every deposit. With that in mind, it may become more understandable why bonuses need to have wagering requirements.

Still don't get the concept of wagering? Don't worry, here's an example. Say you deposit 100 credits and claim a 100% bonus (from our list of best casino bonus offers of course). The casino in question will now add 100 credits to your balance to match your deposit. In this case, let's say that the wagering requirement is 35x. This means that the 100 credits received from the casino has to be turned over 35 times, which in turn means you have to wager 3500 credits. Being a game of chance, there is no real strategy that will guarantee you'll beat the casino but seasoned players will likely tell you that the best way to beat wagering is usually by starting off playing high variance games in hope to have a reasonably good win after which you can go for a bit lower volatility and higher bets.

The first thing you should, however, before you start playing with a bonus, is to read the terms and conditions. In fact, you should make a habit out of this as it's the source for most disputes between operators and players. For example, some of your favourite games could be excluded from playing with one of our best casino bonus offers, or may only count 70% towards wagering. Most casinos also have a max bet rule when playing with an active bonus, usually set to 5€ or equivalent. In the past, players would risk having their winnings confiscated if betting higher than allowed, but these days, most casinos on our list of best casino bonus offers, such as Videoslots, Thrills, Kaboo, Rizk, and Slotsmillion have thankfully implemented max bet protection.

🔔 Why Casino Bonuses?

For many online gaming enthusiasts, casino bonuses and incentives in the form of promos or loyalty systems are the enticements that keep them interested and often turns them into loyal customers. For those who are looking to extend their play time and maximise the value of their deposits, bonuses will come to good use. Casinos, of course, want their players to return and they'll stretch quite far to accommodate you. From the avid veteran gambler to the recreational player, it's no secret that we all love free stuff.

The bonuses, however, are for the most part not what they used to be. Back in the days, most markets were unregulated and online casinos could thrive thanks to low taxes and total freedom. A company operating from Malta could target Swedish players without having to pay taxes to the Swedish government and the British Gambling Commission was less stringent than it is today. Following the recent developments on the European gambling map, costs have increased for casinos and in Sweden, bonuses are in danger of extinction.

On Bigwinboard.com, we continually deal and negotiate with casino managers in order to provide our visitors with tailored and exclusive casino bonuses. The stronger we grow, the better the deals we will be able to negotiate for you. If you're a new player we recommend you to go for a regular 100% casino bonus. It will give you an edge against the casino but with less wagering than larger bonuses. However, don't just take any casino bonus you can get your hands on. Many times, unfortunately, players funds will be locked into nonsense bonus terms which is why we're here to help.

🔔 Which games are best to play with our best casino bonus offers?

Online slots is a game of chance so there is not a single strategy or approach that will give you any sort of guarantee. With that said, there are a few things that you can try in order to increase your odds. With some basic knowledge of the various math models you may even boost your chances of beating the wagering requirements. The first thing you need to think of is to stick to casino bonuses that are worth the time, effort and investment. There are as many bad bonus offers out there as there are bad casinos, so choose wisely.

Sticking to our list of best casino bonus offers will ensure that you get some of the best deals currently available on the market and on trustworthy casinos only. Still, even if you’re playing at a reputable casino, it is always important to read the bonus terms and conditions. There might be some limitations that you need to be aware of, such as a max bet rule, or info on specific slots that do not contribute towards wagering. If you’re unsure of anything, contact customer support and ask them directly.

So, which games to take on then once you've claimed one of our best casino bonus offers? Well, a popular approach is to go for high volatile games first and later switch to low to medium variance math models once you’re convinced that wagering will be cleared. The reason for this is that volatile games usually offer far greater potential and in order to beat wagering you will need some headroom. Not necessarily 1,000x - 2,000x wins, but at least a couple of 200x+ wins. Besides, most players want to walk away with as much money as possible, so going for the low to medium variance options will rarely result in anything of much value. Here are some examples of popular low, medium and high variance online slots for you to play with our best casino bonus offers:

🔴 Popular high variance slots

Dead or Alive 2 (NetEnt): This highly anticipated follow up to NetEnt's iconic 2009 release Dead or Alive does not disappoint. Played utilising a 5-reel, 9-payline set up, Dead or Alive 2 is one of the most volatile and highest paying, non-jackpot online slots ever released. Developed in a first-of-a-kind collaboration with the gaming community, the game dished out wins of over 100,000 times the stake within the first few weeks of its launch. The base game can be a bit of a drag at times since most of the potential is allocated towards the free spins feature, but if you become one of the lucky few to land one or more wild lines during the free spins, you can just sit back and watch potentially life-changing wins count-up on the screen. The game comes bundled with three different free spins options of varying volatility - medium, high and ultra high, but it's the latter that most players take aim for. With proven maximum potential of 111,111 times your stake, Dead or Alive 2 is a must try! Recommended best casino bonus operator: Videoslots.

Lil Devil (Big Time Gaming): One simply cannot speak of high variance slots without bringing up Australian provider Big Time Gaming. Known as the creators of the celebrated Megaways engine, this developer has has its main focus in the field of high volatility and spends all its time perfecting its math models for each new game released. Not only that, Big Time Gaming also has a knack for designing highly unique and innovative games which is clearly displayed in their 2019 release Lil Devil. With music provided by iconic band The Cult, this 6-reeler stands out by utilising a 4,096 win all ways setup rather than Big Time Gaming's in-house developed Megaways game engine. It may not feature the best looking visuals around, but it's undoubtedly unique. Whilst there is a chance to score massive wins even in the base game, it's the bonus game that will get the blood pumping. With multipliers of up to 144x, this monster slot can lead to payouts of a whopping 36,800 times your total stake! Recommended best casino bonus operator: Fun Casino.

Book of Dead (Play'n GO): It may be a clone of one of the most iconic land-based machines in the world, but Book of Dead from Swedish provider Play'n GO has certainly taken on a life of its own. Released back in 2016, it has become one of the most successful online slot ever released and consistently tops the list of slots most frequently dishing out wins of 2,000x or more. It's hard to say exactly why this game in particular has become so successful, but its simple premise, intriguing visuals, superb math model and excellent potential is certainly part of it. Landing 5 scatters in the base game awards an instant 200x cash prize, but 3 will be enough to initiate the bonus round. Once in, you'll benefit from special expanding symbols that expand to cover the full reel when appearing in view. Moreover, the game is known to be extremely generous with retriggers from time to time. Land a full screen of Rich Wilde's and you're looking at a payout of 5,000 times your stake!

Bonanza (Big Time Gaming): The highest scoring game in the history of Bigwinboard.com, Bonanza completely transformed the iGaming landscape when released in 2016. Albeit not the first slot to feature Big Time Gaming's Megaways engine, it's the slot that eventually became most widely associated with it. What stands out here is the quirky hillbilly banjo soundtrack played by the creator Nik Robinson himself. Whilst there are an abundance of similar styled Megaways slots available now, Bonanza is the one title their all modeled after. For those struggling to wager their casino bonus, Bonanza can work wonders. This is a slot you can literally play for hours on end without the balance barely moving. Of course, it can be brutal on a bad day but overall it's quite lenient if you're looking to get some extra play time. Recommended best casino bonus operator: Casilando.

Golden Fish Tank (Yggdrasil Gaming): Old but gold! This cute and colourful classic from Swedish developer Yggdrasil Gaming comes with a lot of fun features and modifiers that can work together to reward you some pretty solid wins. With its 96.4% theoretical return to player and medium variance math model, it's a great alternative for some extended play time. Golden Fish Tank utilises a simple 5x3 reel matrix and is quite simple when it comes to the gameplay. Triggering the bonus will take you to a picking screen where you get to reveal modifier extras hiding behind various sea shells. Pick good ones and they'll work together to provide you with wins of up to 400 times your stake per single spin. Recommended best casino bonus operator: Rizk.

Steam Tower (NetEnt): Steam Tower is a classic NetEnt slot that was released back in 2015. In spite of its old age, it's anything but dated and still stands the test of time. What's even better, Steam Tower can work wonders for wagering as it comes with a very merciful math model and a higher than usual 97.04% RTP. Because of this, it has become one of the most successful online slots ever released. The goal here is to land scatter symbols during the bonus which will help you climb towards the roof top. If you managed to reach all the way up, you'll have a cash prize of 500x waiting for you. It's not the highest paying slot out there, but it's certainly one of the more unique and fun to play.

🟢 Popular low variance slots

Starburst (NetEnt): It's hard to put into writing just how iconic Starburst is in the virtual casino world. All slots players have come across this slot at some point during their slotting career, either through a free spins offer or in some slots tournament. Heck, even non casino people have probably heard of Starburst as it's been used in endless of casino ads. Launched by NetEnt in 2012, Starburst is still the single most played online slot in the world. It's incredibly simple too - there are no free spins or random features, just spin the reels and hope to land a full stack of wild stars on either of the three central reels. Doing so will unleash a retrigger which can lead to more wild stacks and additional respins. This relaxing, and equally thrilling slot, has the capacity to dish out wins of 500 times your stake in a single spin which, along with a lenient math model, can work your way when trying to beat wagering. Recommended best casino bonus operator: Wild Blaster.

Agent Jane Blonde (Stormcraft Studios): The original Jane Blonde slot was released in 2005 at a time when Microgaming was dominating the online casino industry. Although sill a force to be reckoned with, Microgaming has stepped back a bit to allow its partnering studios to do some of the work instead and it's one of those studios that was assigned the task of producing a follow up title - Stormcraft Studios. The game was revealed at the 2018 London iGaming conference with Microgaming using what seemed like a significant cut of its promotional budget to hype the game. It didn't quite become the hit they were hoping for and it scored a disappointing 29% score on our site, but if you're making an effort to complete wagering, Agent Jane Blonde could very well end up being what you're looking for.

🔔 What Types Of Casino Bonus Offers Are Available?

One benefit of playing casino games online is the availability of casino bonuses as a new customer. At land-based casinos, customers may be offered free alcohol and food, but rarely are they given free money to gamble with unless they're high rollers. There are many different type of bonuses on the iGaming market and the type which you can claim will usually depend on a number of factors including where you live and thus the licensing jurisdiction you come under, the deposit method used, of course, the online casino where you play at. Below, we are going to list the most common types of casino bonuses that you are likely to come across today.

No-Deposit Bonuses

Back in the days, before the market became heavily regulated, casinos could be extremely generous with bonuses and even offer one without the need for you to make a deposit. You would simply get free cash as an incentive to sign up to the casino. Granted, they are harder to find these days, but there are still a few no-deposit bonuses on our list of best casino bonus offers. It's a great way for you as a player to explore the casino and get a feel for what it has to offer before making your own deposit, plus it gives you the chance to win some money without any risk. However, these types of offers typically come with strict terms and conditions, including max cap on the cashouts and ridiculous wagering requirements.

Matched Deposit Bonuses

The matched deposit bonus is the most common type of casino bonus and is offered at more or less all gambling sites as their welcome bonus offer for new players. As the name suggests, a matched casino bonus means that your deposit will be matched a %, usually in the form of 100% or, more rarely, 200%. There are even bigger bonuses of 300% or higher on the market, but the sites that offer those kind of bonuses are more often than not shady and will rip players off using predatory terms. We suggest you do not claim such bonus unless it is listed on our site.

Free Spins

As video slots started to become popular, so did free spins offers. Again, back in the glory days of online gambling, before over regulation started to happen, casinos were very generous with giving out free spins. There is even an example of a player at Rizk Casino winning over £10k having started with 10 free spins. Still, nearly all welcome bonus offers will also include a batch of free spins that will usually be restricted to specific slots, the most common ones being NetEnt's Starburst and Book of Dead by Play'n GO.

Reload Bonuses

The reload bonus is similar to the matched deposit bonus, but is offered to existing customers as opposed to new players. Of course, this is a way to encourage returning customers to play more, but is also a way to reward loyal customers. Usually, the reload bonus will be lower than the matched deposit bonus and is typically offered in the form of a 50% bonus. A lot of the casinos listed on our best casino bonus page like to tie reload bonuses into their promos and offer them on a weekly basis to returning customers. Hence, many times it can be beneficial to stick to one or two casinos.

High Roller Bonuses

High roller bonuses are designed for players with large bank rolls and who plan on wagering large amounts of cash. Granted, these players will receive the biggest bonuses available on the market. High roller bonuses are obviously worth larger amounts compared to the standard welcome bonus. They may also benefit from better terms and conditions and not have any max bet rules applied. Not all casinos are good for high rollers due to their small size. Stick to the ones listed on our High Roller Bonus page.
