  • Expiration Time: 7 days

Aside from the obvious huge potential value of this casino bonus, Caesars is one of the best high value casino bonuses because of the relatively low 10x turnover, and excellent game contribution rates that make it possible to actually have some withdrawable cash at the end of the bonus playthrough. And the added cherry of the no deposit bonus is just *chef's kiss*.

DraftKings Casino is another $2K casino welcome offer, with the only monetary difference being the nice no deposit bonus Caesars offers. Game contributions rates for this high value bonus are pretty good, and the turnover is right in the middle for US online casinos so with some smart betting having some cash at the end is doable.

Claim $500 offer

100% Deposit Match up to $500

While the value may not be at the very top, this is one of the biggest bonuses with a real potential to see some actual cash at the end of it.

Why Claim a Big Online Casino Sign Up Bonus

Let's get the obvious answer out of the way first: bigger bonuses give you more bonus funds to wager without needing to spend your own cash. But you already knew that, and in general this is the main reason players seek out the highest online casino bonuses. 

But aside from that, a larger sign up bonus does tend to enforce the fact that the online casino is actually quite good. These sites are not in the business of giving away money, so if they offer a nice bonus to get new players to join it generally means they think their product is good enough to keep players coming back even after they use up all the bonus funds. 

  • More Bonus Funds to Play With
  • Bigger Bonuses Usually Means Better Casinos
  • Higher Potential Amount of Cash Can Be Converted

Reasons to Avoid The Highest Online Casino Bonuses

In general there are only a few reasons why higher value casino bonuses might not be as good as they seem at first glance. But without a doubt the biggest reason not to just grab a big casino bonus is if the online casino is not legal and licensed in the US. We only review and showcase fully legal and licensed casinos, so you can be assured your money and data is protected to a high standard approved by state and federal gaming commissions.

Do Not Use Offshore Casinos

Offshore casinos like Bovada, Las Atlantis or Ignition may seem exciting with several thousand dollars on offer from the bonus (we've seen up to $14,000), but in reality the terms associated give you almost no chance to actually convert the bonus to withdrawable cash, and there is not guarantee you'll get your money in a timely manner, or at all.

That brings us to our main reasons the highest online casino bonuses may not actually be the best:

  • High Turnover: Turnover is how many times you need to wager your bonus funds before any winnings can be withdrawn as real cash. The higher the turnover the less likely you are to have any money left over at the end.
  • Low Game Contribution: Game contribution reflects how much each dollar wagered counts towards the turnover of a bonus. Since casinos don't want these huge bonuses to be taken as cash easily, they tend to only let games that payout less (like slots) contribute fully, while blackjack might only provide 20% or each dollar bet to the turnover making it take much longer or just massively reducing the chances of winning in the long run.
  • Short Expiry: Unless you're ready to spend sever hours a day playing the slots, having a longer expiration period on your bonus funds can be incredibly important to actually fulfil the turnover requirement so you don't just lose all your bonus funds. If an online casino is asking you to play through a $100 bonus 10x in just a day, it may be tough to meet, especially if you prefer games that have a lower contribution.
