Different Types of Casino Bonuses

Casino bonuses come in a growing number of different options. Each has its pros and cons, but it is important that players know what each one entails before claiming it.

Match deposit bonus

One of the most common bonuses, this option requires players to make a deposit which the casino will then match. Often given to players newly signing up to the casino, this match can be anything from 50% or less to as much as a 600% casino bonus. It all depends on the online casino though.

No deposit bonus

Similar to the match deposit, this is often awarded to newly arriving players. Simply by signing up, players will receive a small amount of cash to play with on the casino site. It’s entirely risk-free and doesn’t require a deposit.

Free spins

Linked with both of the aforementioned bonuses, free spins can be both no deposit or deposit spins. Players will get more spins with a deposit bonus but, for both bonus types, the spins will be linked to a specific slot or slots.

Advantages of 400% Casino Bonuses

Claiming a 400% casino bonus can be a really lucrative bonus. Even just a small deposit will yield a decent-sized bankroll when this bonus is claimed. Excitingly, this type of bonus also means that players can play a range of games — there are usually not many games exempt from a bonus like this. However, live casino games tend to be the ones that can’t be played, unless otherwise stated by the casino.

Of course, the big upside here is that it’s also possible to win real money too.

Disadvantages of 400% Casino Bonuses

However, there are some downsides to playing with a 400% casino bonus. First, the bonus is likely to have a minimum deposit and maximum deposit requirement. As it’s matching the deposit with such a high percentage, these deposit limits are likely to be very low. This means that players won’t be playing with such a huge amount of money even with the massive match.

The other major downside is that this type of bonus will have wagering requirements attached. These will include playthrough requirements, time frames, and even minimum and maximum withdrawal limits. Failing to meet any of these requirements can result in the winnings getting forfeited and the player walking away with nothing even after claiming such a decent bonus. The terms and conditions should always be checked prior to accepting the bonus.

Things to Know About the 400% Casino Bonus

One of the first things to consider when playing with a 400% casino bonus, is the casino that is offering it. With huge casino bonuses like this, players do run the risk of being scammed. Because of this, it is important that players make sure they check out the security and reliability of the casino before they sign on. Checking for a license at the bottom of the main page is the fastest way to do this.

Another way of identifying if the casino is legit or not is to check out the terms and conditions attached to the bonus. Reputable casinos will have decent wagering requirements, standard timeframes, and pay out well. In contrast, suspicious casinos will often have unreasonable wagering requirements in place that can never be achieved. On top of that, it’s likely that they will pay out in increments meaning players might never get their winnings.

Summary

While a 400% casino bonus can look good on paper, the reality is often not the case. In order to get the best out of the bonus, players need to make sure they are playing at a licensed casino. Checking the terms and conditions before making a deposit to claim the bonus is also essential to having a fun time gaming.
