How We Find the Best Gambling Bonuses

How We Find the Best Casino Bonuses

We focus on four important areas when assessing the overall appeal of an online gambling bonus. The best bonuses perform well in all four categories:

hand-with-money

Value

We search for online bonuses that match a large percentage of your first deposit, and we also make a note of sites that offer high upper limits.

account

T&Cs

We know that the most attractive bonuses have realistic wagering requirements, giving you a strong chance of cashing out a profit, so that is an important consideration when we conduct our reviews.

Variety

We examine the variety of bonuses on offer at each site, and lean toward sites that have a wide range of welcome, reload, cashback, and loyalty bonuses so that all players can find a bonus that works for them.

Availability for Gambling Types

Having a great bonus isn’t enough, the gambling sites we recommend also need to have excellent products, like slots, table games, live dealer casinos, poker rooms, and sportsbooks

Types of Bonuses and Promotions

Types of Bonuses and Promotions

Online casinos, poker rooms, and sportsbooks offer large welcome bonuses to attract new customers. They compete with one another to provide the most eye-catching promotions, which is great news for players. It means you can shop around for the best deals, with the most attractive wagering requirements.

These casino sites also need to work hard to maintain loyalty among their existing customers, so they offer recurring bonuses as well. Here’s a look at the most popular types of bonuses available:

BetChan Welcome Bonus

Welcome Bonuses

Welcome and sign-up bonuses are the most common kind of promo you’ll find at online casinos, sportsbooks, and poker rooms. They typically include a deposit boost, free bets, or free spins.

The welcome bonus is intended for new players only, so if you’ve deposited at the site before, you’ll have to use a reload bonus instead.

Now that cryptocurrency is a big part of online gambling, casinos will offer both a regular welcome bonus and a crypto welcome bonus. Crypto bonuses tend to come with higher limits since casinos want to prioritize crypto deposits.

Nonstop Casino Reload Bonus

Reload Bonuses

A reload bonus rewards existing customers for topping up their account balances. It is similar to a welcome bonus, as the site will match a percentage of your deposit with bonus credits. However, reload bonuses are generally smaller than sign-up bonuses. Yet they also often have lower rollover requirements.

Virtual Betting Bonuses

Referral Bonuses

This bonus rewards you for referring your friends to a gambling site. You can request a referral link and send it to a friend. If your friend signs up using that link and makes a deposit, you will be given bonus credits.

The amount you receive will depend upon the size of your friend’s deposit. Your friend will also receive bonus credits, so it is not a one-way street.

no-deposit-bonus-1

No-Deposit Bonuses

No-deposit bonuses are a risk-free way to test out games for free at online casinos. Typical no-deposit bonuses include either free spins for select slots games, or a $15-$25 chip to play table games. No-deposit offers come with high rollover requirements, which encourage players to make a deposit in order to cash out any winnings from the free chip.

Cashback Logo

Cashback Bonuses

Some casino sites will give you back a percentage of any net losses that each week, while others give you back a percentage of your overall betting volume. Usually, cashback bonuses are around 10% of your losses and have no wagering requirements.

Sports Betting Bonuses

Sports Betting Bonuses

Sports betting sites also offer bonuses for first-time users and recurring players. Instead of free spins on slots games, they’ll offer free bets on certain sports, usually with restrictions on the level of risk the wager has. You can also claim deposit bonuses to boost your bankroll. Rollover on sports bonuses is usually around 10-15x, compared to casino bonus rollover, which is usually 30-40x.

Game-Specific Bonuses

As you might have noticed, some casino bonuses are only applicable to certain games. While most deposit promos are usually good for slots and table games (excluding live dealer), there are specific bonuses for games like blackjack, poker, and even slots.

  • Slots Bonuses – When a casino gives you free spins, it’s often for a specific slot game/s. The spins have a pre-assigned monetary value, like $0.10. Slots bonuses are a cheap way for the casino to get you interested in their new or popular games.
  • Blackjack Bonuses – Deposit bonuses might not allow you to play blackjack, since it’s one of the most profitable casino games. However, some casinos offer blackjack-specific bonuses. These funds are often only valid for games like blackjack with 6:5 payout, or Spanish 21. The bonuses often come with high wagering requirements to account for the profitability of the game itself.
  • Poker Bonuses – Online poker is a different beast from other casino games because they are played live with other users. Casinos offer poker deposit boosts, but most of the funds are unlocked over time as users accumulate rake. Sites also offer freeroll and free poker tournament entry.
Understanding Bonuses

Understanding Online Casino Bonuses

Online gambling site bonuses are different from traditional casino comps, but they are still designed to attract new customers and reward returning players. However, the math that goes on behind the scenes is more important than most people realize.

To be an informed player, it’s important to read the terms and conditions and understand the rules of the bonus you’re claiming. Here are some tips for determining which bonus is a winner, and which one might be a dud.

Wagering Requirements

The wagering requirement is the most important condition attached to a bonus. It tells you how many times you must roll your bonus funds over before they convert to cash.

For example, if you have a $100 bonus with a 5x wagering requirement, it means you need to place $500 worth of bets before you can cash out. However, if it has a 50x wagering requirement, you need to place $5,000 worth of bets before the funds will convert to cash.

The best online gambling bonuses come with low rollover requirements. The 5x wagering requirement on Bovada’s sports betting bonus is attractive, and so is the 30x wagering requirement on casino bonus funds at DuckyLuck.

Bonus Contribution Rates

Some games will count 100% toward completing the wagering requirements on an online bonus, but others will not. You will normally find that slots will count 100%, but table games will only count 20%, 10%, or 5%, as those have a very high Return to Player (RTP) rate.

If you are playing a game that only contributes 10% towards the wagering requirements, it means that $0.10 of every $1 you wager will count. If the rollover requirement is 35x, but you are playing a game that contributes 10%, it effectively takes the rollover requirement to 350x.

Minimum Deposits for Bonuses

You will need to make a minimum deposit to redeem the vast majority of online gambling bonuses. There are a few no deposit bonuses on offer, but you invariably need to deposit and risk your own money to claim bonus funds.

The minimum deposit required to qualify will be displayed alongside the bonus or in the terms and conditions. It is just $10 at some gambling sites, but you need to deposit at least $100 at others.

Bonus Time Limits

You will need to fulfill the wagering requirements within a certain number of days after receiving bonus funds. If you do not use them within the allocated time, they will be forfeited. That means they will be removed from your account.

The best online sportsbooks, casinos, and poker rooms will give you ample time to complete the requirements. It may be 14 days or 30 days. Just check the T&Cs for details.

Bonus Restrictions

Some online bonuses offers have restrictions in terms of the games you can play. For example, you may not be able to play live dealer games with casino bonus funds. Most casinos do not allow you to play craps either, as some craps bets have very high RTP rates.

There may also be minimum odds restrictions on sports betting bonuses. For example, you might need to place a bet at minimum odds of -200 (1.50), or you may not be able to place a futures bet or cash out your bet before the game ends.

Bonus Codes

Some sites require you to enter casino promo codes if you want to claim certain bonuses. For example, you can use CRYPTO300 to claim the 300% first deposit crypto bonus at Wild Casino or WILD250 to claim the 250% first deposit bonus on a fiat-based payment.

It is important to check whether you need to enter gambling sites’ bonus codes to claim the offers or if they will be applied automatically. If it is unclear, you can ask the customer service team.

Common Mistakes We See Players Make Involving Bonuses

If you’ve ever seen people leave reviews for online casinos, they often complain about not being able to withdraw their funds. We’re sure that 95% of these people didn’t read the terms and conditions for the bonuses they claimed, which impacted their ability to withdraw their money.

Here are three common mistakes casino newbies often make when it comes to bonuses:

The bonus rollover applies to deposit AND bonus

This is a big one. The rollover on most bonuses will apply to both your deposit amount and the amount of bonus funds you’ve received. So, if you deposit $100 and receive $200 on a 25x bonus, you need to wager $7,500 before cashout, compared to $5,000 needed to clear just bonus amount rollover. The solution? Read the terms and conditions.

Bonuses have max cashout limits, too

You hit the jackpot and have $100,000 sitting in your casino wallet. But, when you attempt to withdraw your winnings, you’re denied.

Even if the maximum withdrawal limit on your payment method is more than $100k, the bonus funds you used to win the jackpot have a max cashout limit (usually 10x). This means you can’t withdraw more than 10x the bonus amount. So if you claimed a $1,000 bonus, you can only withdraw $10,000.

Contribution rates vary per game

When you are working toward your wagering requirements, certain games contribute more toward the rollover than others. Most slots games count 100% toward the requirements, while games like blackjack can account for 10%. You might think you’ve wagered all required to cashout, but if you were playing lower-contributing games, you won’t have met the mark.

Gamble Responsibly

Gamble Responsibly

Online casino and sportsbook bonuses all look enticing, but it’s important to recognize when not to claim a bonus. Not everyone should claim a gambling site bonus, especially if you have a small bankroll and gamble casually.

Wagering requirements and rollover can make it difficult for casual gamblers to withdraw winnings, so always read the terms and conditions before claiming a bonus.

If you feel that your gambling habits are more than just a hobby, it might be time to find help. There are many resources available for people with gambling addiction.

Online Casino Bonuses Summary

Online casinos always have many rotating bonuses and promotions on offer, so if you’re a frequent gambler, it’s a good idea to watch for new opportunities.

The best bonuses have low wagering requirements and flexible limits that let you customize how you want to play. Before you claim a bonus, make sure you understand how much you have to wager, what the bet limits are, and what games or wagers are restricted.

All of our top casino sites, sportsbooks, and poker rooms have promos worth claiming, no matter if you’re a novice or a pro.
