As mentioned, online casino bonuses play a massive role in rating the best sites. At JohnnyBet, we understand the role of bonuses, so we provide the latest referral codes to use on these sites to claim bonuses, including exclusive bonuses we negotiate on your behalf. You can find our latest promo codes once you click on the selected brand logo on the list above or go to our article which gathers all the best casino and bookmaker promo codes.
The top-rated online casinos feature a lineup of bonus offers tailored for new and existing players. Below are the different best bonuses for online casinos to expect:
2.1 Welcome Bonus
It is also called the sign-up bonus or a new player bonus, awarded to new online casino members. The bonus comes in two forms, including a deposit match bonus, the most common, or a no deposit bonus, which is rare. The deposit match bonus is when the online casino matches your first deposit(s) by a set percentage. For example, a 100% bonus of up to €500 will have a player double their first deposit. Free spins may be added to the package, allowing casino members to use them on the slots.
A no deposit bonus works as the name suggests. A player will not need any deposit to claim the bonus. In such cases, using exclusive links or bonus codes, like the ones we provide, are often the keys to unlocking the bonus. The drawback is that no deposit bonuses are low in value, whether as bonus cash or free spins.
2.3 Reload Bonus
A reload bonus works similarly to a welcome deposit match offer, except it is available to existing members who have already claimed the welcome offer or made more than one deposit at the gambling site. An online casino may tailor them for specific days, where players deposit a certain amount to have it matched by a set percentage. The common reload bonuses are weekly, weekend, and monthly reload offers.
2.4 Cashback Bonus
Losses are part of the game when gambling and cashback bonuses offer a soft landing by refunding a small percentage of the net losses. Like reload bonuses, you might find weekly and weekend cashback bonuses, where the casino refunds net losses at an average rate of 10% and 30%.
2.5 Referral Bonus
Imagine introducing your friend to join an online casino, and you are awarded generously for it. The best online casinos offer a referral bonus when you refer your friend as a new customer. However, some online casinos have a condition that your friend must deposit before they unlock your referral bonus.
2.6 VIP/Loyalty Bonus
The best casinos online feature a VIP/loyalty program that seeks to award VIP players and loyalty. These programs are tiered, with each tier having benefits and perks. These benefits include cashback bonuses, high withdrawal limits, personal account managers, etc. The higher you climb the tiers, the better the perks.
3. Great Features of Online Casinos
While looking for the best casinos for online players, you must consider several features before making an informed decision. These features include
Legality and security: The best casinos online are licensed and boast top-level safety and security through the latest technological tools like SSL technology, firewalls, and 2FA.
Bonuses and promotions: The top-rated casinos we recommend offer a generous lineup of offers tailored for new and existing players. They include welcome bonuses, reload, cashback, VIP, and tournaments to compete against each other.
Game selection: The game selection also plays a vital role in determining the best online casinos. Top operators offer various games in different categories from reputable and certified game providers.
Friendly user interface: It is not a complete online casino if the user interface is not friendly. The lobby should be easy to interact with and well-organised without clutter or congestion.
Mobile casino: The top-rated online casinos are mobile responsive, thanks to HTML5 technology. In addition, some go a notch higher to launch a dedicated app version for an enhanced gaming experience, which we discuss in a greater detail, for example in our article including Betwinner mobile app instructions.
Multiple payment methods: Top casinos online ensure players have numerous payment options to facilitate easy deposits and withdrawals. These options range from credit/debit cards, prepaid cards, e-wallets, bank transfers, and even cryptocurrencies.
Like finding the best online casinos, finding the best casino bonuses online can be daunting. However, our experienced team of experts have a guide you can follow while picking the best casino offers. Here are the things to look out for:
Terms & Conditions: The first rule of thumb is to read the bonus rules to ensure they are favourable regarding minimum deposits, wagering requirements, bonus duration, etc.
Games eligible: The best casino offers will be valid for playing almost every game. This ensures you have fun while also fulfilling wagering requirements quickly.
Low wagering requirements: Low playthrough requirements are other aspects we look for when picking the best casino offers. You can meet the requirements quickly and withdraw the bonus.
Look out for bonus duration: Some bonuses have a short validity timeline, which may be challenging for you to claim and meet the wagering requirements. The best casino offers will have a lengthy validity timeline, mostly 30 days or more.
In the reviews on our website, for instance in the one including Betano promo code, we provide a brief overview of the brands' offers. However, to find all the currently available games and all the details regarding particular promotions, it is always advisable to check the game library on the website itself and read the terms and conditions section carefully.
