The 3 Best Online Casino Bonuses Ever Created (Updated for 2021)

The best online casino bonuses ever created are not easy to find. The current online casino market is saturated with hundreds of online casino offers, and with many of them being exclusive to be played in certain countries, we know that the best online casino bonuses can be quite difficult to come across. As such, we’ve created an entire article dedicated to three of the best online casino deals that you will find on the internet in its current state. This should save you all the time and trouble that comes attached to finding the best offers on the internet, and your friends at The Casino Wizard are more than happy to help!

1 BitStarz Casino
5 BTC / €500 + 180 FS T&C apply PLAY
2 William Hill Casino
150% to €150 + 50 FS T&C apply PLAY

We’ve taken two other factors into consideration when judging the bonuses.

The first and most important one is the reliability of each online casino on the list. It doesn’t matter how good an offer seems to be if the online casino that is handing it out doesn’t properly support players or even pays out its bonuses once people have gone through the wagering requirements. The second factor that we’ve considered is the profitability of each of these bonuses. Some amazing offers only give you 25 free spins or a match deposit total of up to €100. Not to take anything away from those, but we believe that there are many other bonuses on the internet that can help you get loaded in a matter of weeks with a little bit of luck.

BitStarz Casino Welcome Bonus – Best Match Deposit Bonus Deal

The BitStarz welcome bonus is a combination of various deposit bonuses that could see your account credited with up to 5 BTC as well as 180 free spins if you complete the deposit requirements of each bonus. You won’t be getting free spins on their own – you will also get a ton of cash to use on the site’s best online casino games. What’s not to like about this amazing promotion? The BitStarz casino welcome bonus is the start of a cryptocurrency journey that rivals the internet’s best online casino promotions. Bonus cash, easily obtainable free spins, and a gallery of games where you can play them freely. There’s truly nothing to gate about the BitStarz welcome bonus.
