It’s important for you, as a gambler, to realize that many casino gambling websites will be willing to offer you welcome bonuses. The key is knowing how to distinguish the best from the rest. The list above is what we believe are the best online casino welcome bonuses that you’ll be able to find in 2021.

How did we come to this conclusion that these are the best 2021 welcome bonuses? We did the research, looking through hundreds of sites until we found the best. And we considered the following criteria:

  • Size of percentage bonus: Most welcome bonuses are doled out as a percentage of your original deposit of first few deposits. The higher the percentage, the more you’ll be able to bet without having to add more of your own funds.
  • Size of bonus limit: Most online casino welcome bonuses will let you get a bonus of a certain amount before cutting it off. You’ll see something like “up to” or “max limit” listed in sight of the promotional page. The higher that limit, the more that you can get out of the welcome bonus.
  • Rollover requirement: This is an underrated part of the online gambling bonus realm that you should take into consideration. Welcome bonuses are subjected to a rollover requirement that determines how much you have to wager before you can collect any winnings attached to the bonus. The lower the requirement, the quicker you can actually realize the impact of the bonuses.

When you put all of these facets into one, you get a complete picture of how welcome bonuses at online casinos work. There is no perfect bonus, but some do a better job of balancing out these elements than others. The bonuses we’ve listed here stand above all others in the online casino world.

Having access to these bonuses is extremely valuable. As we mentioned above, you get the biggest boost from welcome bonuses when it comes to all possible promotions from gambling websites. And you only get once chance to take advantage of these at particular sites, which is why you need to know which ones yield the most lucrative rewards.

But in fact, the rollover of 35x for this welcome bonus is quite reasonable, especially considering all you’re getting from the Las Atlantis.

The maximum amount that you can win from the bonus is 30 times the deposit. Even though that limit is in place, the high limit that you get for accepting the bonus means that you can win a whole lot (up to $420,000), all from bets essentially gifted to you by Las Atlantis.

Vegas Casino OnlineVegas Casino Online actually offers several different welcome bonuses from which you can choose. We love all of them, but we particularly enjoy the bonus that allows you to redeem it 11 times. That makes for so many redemptions that it’s almost unfair to call this a welcome bonus and maybe more accurate to call it a running bonus.

What you’ll be getting is bonuses of up to $1,000 for your first 11 deposits at the site. These bonuses are all 100 percent match bonuses. In other words, if you deposit it $500, they’ll give you $500, and just like that you’ve got $1,000 with which you can bet.
