What is a Casino Bonus?

Casino bonuses are promotional offers that provide you with extra cash or free spins to play gambling games. The contents of deposit bonus codes and how you qualify to receive them are entirely dependent on the promotion. Terms and conditions affect how you can use the promotional offer.

Overall, casino bonus codes aim to give you an incentive to sign up to the casino. You should always analyze casino bonuses on offer at a gambling site before signing up. That way, you can see whether a bonus is worth it.

Opinion on casino bonuses is divided. Ar best, free casino bonus codes can add hours to your gameplay. At worst, bonuses are worthless additions to your account. Our final judgment is that most players would be stupid not to take advantage of these deals.

10 Best Online Casino Bonuses

1. Slots of Vegas – $5000 + 50 Free Spins – Code: MAGIC400

slots of vegasSlots of Vegas has loads of great casino bonuses and promotions, but the biggest deal has got to be its welcome offer. If you sign up through Gambling360.com, you get a 250% match up to $5,000 as well as 50 free spins on some top-rated slots.

Probably, the best thing about this bonus offer is that there is a 5x wagering requirement attached. This is one of the lowest terms we have ever seen, which means you have ample opportunity to withdraw your winnings.

2. High Country Casino – 500% Welcome Bonus + 50% Cashback – Code: HIGHWINS

high countryHigh Country Casino offers players an easy way to maximize their playtime with a 500% match casino bonus on their first deposit. If that wasn’t enough, there is also a 50% cashback attached, meaning that if your luck runs dry, you will still get half of your deposit back.

Wagering requirements on both the initial match and the cashback casino bonuses is 45 times. This is a bit high, but the casino gives you two opportunities to win on the offer.

3. BoVegas Casino – 300% Welcome Bonus + 25 Free Spins – Code: NEVADA300

bovegas online casino siteIf you sign up to BoVegas Casino through Gambling360.com, you get access to a 300% match welcome bonus which caps at $6,000. You also get 25 free spins to use on a slot game of your choice. With so many Realtime Gaming slots available, you have a hard choice to make regarding where to use these free spins.

If you stick to using your bonus cash on slots, you only have to meet a 30x wagering requirement. This is very low in comparison to some of our other recommended casinos.

4. Free Spin Casino – 100 Free Spins – Code: PARADISE

free spin online casinoFree Spin Casino providing players with ample free spins shouldn’t be a surprise. Each month, the casino runs new promotions where you can claim free spin bonuses on new games.

Currently, Free Spin Casino is running a promotion where you can claim 100 free spins on the game Wild Hog Luau. One of the best things about the offer is that the playthrough requirements are relatively low at 20x, and there is no maximum cashout.

5. Golden Lion Casino – 125% Card Match – Code: CHARMS125

golden lion online casinoGolden Lion Casino has tons of bonus offers you can claim as an existing player. Our favorite offer by far is the 125% casino bonus match on deposits greater than $200. You can use the bonus on games like blackjack and video poker, which isn’t often seen at other casinos.

Another great aspect of this offer is that it has a 45x wagering requirement. This may seem very high, but usually, when other casinos offer bonuses you can use on card games, the wagering requirements are as high as 90x.

6. SlotsPlus – $20 No Deposit Bonus – Code: 20FREECASH

slotsplus casinoDo we really need to sell a no deposit casino bonus to you? SlotsPlus offers players the chance to claim $20 in free cash as well as 20 free spins for the RTG classic Gemtopia.

You get a chance to win cash without making a deposit. Unfortunately, your winnings are capped at $150, but this even quite high for such an offer.

7. DomGame Casino – $15 No Deposit Bonus – Code: CONSIGLIERE

domgame casinoThis is another Gambling360.com exclusive casino bonus. If you sign up through our provided link and use the bonus code provided above, you get a $15 no deposit bonus. You can only use the cash on slots or specialty games.

Unfortunately, the maximum amount you can win using this bonus is $30. The playthrough requirements is also 50x, which is pretty high. But free is free, right?

8. Crypto Reels – $75 Free Chip – Code: CRYPTOCHIP

crypto reels casinoWhen you join Crypto Reels, you have the option of claiming a free casino bonus chip after you have claimed your initial welcome bonus. As with the other no deposit offers included on this list, your total winnings are capped. However, $750 isn’t a bad take-home sum.

The wagering requirements on this page is 50x, which is pretty high, but we think the take-home offer more than makes up for this setback.

9. Two-Up Casino – 50 Free Spins Casino Bonus – Code: MYSTICAL

two-up casinoTwo-Up Casino has a great 50 free spins bonus which you can use on Realtime Gaming’s 5 Wishes slot game. Playthrough requirements are set at 20x your deposit. (You need to deposit at least $35 to claim this bonus.)

Overall, we love free spins because they open up your mind to games you may not have thought of playing before. And, 5 Wishes is a pretty solid title.

10. Sun Palace Casino – 20 Free Spins – Code: 20FREESPINS

sun palace casinoSun Palace Casino has a no deposit casino bonus to Free Spin Casino. You can claim a free spin or cash no deposit bonus using the above code.  You will then get a free cash or free spins bonus which you can use to play real money casino games.

The maximum amount you can win with this casino bonus is $150, which is not a bad offer for a no deposit bonus.

How Casino Bonus Codes Work

Generally, all casino promotions work in a standard manner. Basically, most bonus codes provide you with a percentage of your deposit in bonus cash. These percentages vary based on the casino. It is usually between 50% and 200%.

Most casinos word their promotional offers in ways such as “200% match sign up bonus” or “get up to *$5000 in bonus cash”. Now, you may be confused as to how this works, but it’s not pretty easy to understand.

Take the first line of the example bonus above; it states that your deposit will be matched 200%. For example, if you decide to deposit $100, you are eligible to receive $200 in bonus cash. We can work this out by multiplying your deposit ($100) by the decimal representing the bonus percentage (in this case, 2.0).

The second example states, “get up to *$5000”. All this really means is that the bonus maxes out at $5000. In this example, to qualify for the maximum amount, you would need to deposit $2500.

It is good to try and take advantage of the big bonuses; however, you will need to deal with the specified wagering requirements if you want to withdraw your winnings.

How Wagering Requirements Work

Wagering requirements may seem a little confusing to players unfamiliar with casino bonuses; however, they are easy to understand. In a nutshell, these requirements stipulate how much money you need to bet before you can withdraw money won with bonus cash.

Let’s say that you are required to meet a 20x playthrough requirement to withdraw your winnings, and the bonus amount totals to $200. All you need to do is multiply the bonus amount by the wagering requirement to calculate how much you will need to wager.

In this instance, you will need to wager at least $4000 before you can make a withdrawal. We know this because 20 x 200 is equal to 4000.

It is essential to note the wagering requirements attached to a casino bonus as some stipulations remove all value from the bonus. In general, most sites will require you to meet playthrough requirements between 20x and 50x your bonus amount. It is in your best interest to find a casino with the lowest requirements.

While wagering requirements make it harder to win real money prizes with bonuses, these offers are still a worthwhile addition to your bank.

Casino Bonus Terms and Conditions

Often, more terms and conditions are attached to casino bonuses aside from wagering requirements, including:

  • Minimum deposit requirements
  • Time restrictions on bonus funds
  • Casino bonus promo codes
  • Game restrictions

Now, some of these restrictions may scare some players off, but they really shouldn’t. Regarding minimum deposits, you can expect to deposit at least $20 to qualify for a bonus.

In terms of time restrictions, casinos usually require players to play through their bonus funds within a month of receiving it.

Some casinos require you to enter a promo code to activate a bonus. This is not true of all sites, though; some automatically deposit bonus funds into your account after a deposit.

Finally, game restrictions aren’t always applicable, but some casinos limit players from playing games with a more favorable house edge. In the case of free spins, the bonus may be limited to a particular game.

As long as you keep these terms and conditions in mind, you should have no problem claiming bonuses and using them effectively.
