What Is a 20% Casino Bonus?

A 20% casino bonus usually belongs to one of the two categories: cashback and reload bonus.

In the case of cashback or rakeback offers, you get to keep 20% of the money you lost; this is a popular promotion, especially among live casino players, as it allows them to recuperate a portion of their loss.

When offering a 20% reload bonus, online casinos let you trigger the same offer daily, weekly or monthly with the same rules attached.

Virtually every gambling site offers cashback or reload offers; however, not all of them offer the 20% variant, making this particular offer relatively rare.

How 20% Bonus Works

Like other casino bonuses, the 20 percent casino bonus comes with Terms and Conditions attached. Compared to other offers, 20% bonuses have relatively low playthrough requirements, making them a welcome addition to a casino's bonus portfolio.

The usual criteria include wagering requirements (most commonly 1x) and the minimum and maximum loss (in case of a cashback bonus). So, if you activate a 20% casino bonus, you may be asked to wager the bonus amount once, but not below or above the limit set out in the T&Cs.

Pay attention to the terms: it may very well happen that the casino imposes no playthrough requirements on a 20% bonus, making the offer even more appealing.

How to Claim a 20% Casino Bonus - Step-by-Step Guide

Here's a short guide to claiming your next 20% bonus:

  1. Find a bonus from the list above.
  2. Register at the casino if you don't have an account.
  3. Make your first deposit (via a welcome bonus or otherwise)
  4. Activate the cashback/reload bonus
  5. Start feeding into the bonus amount by playing the games you like.

As you can see, these offers are intended for existing customers, so unless you have already made at least one deposit, casinos usually won't let you trigger a cashback or reload offer.

Variations of 20% Casino Bonus You Can Trigger

20% casino bonus

As we said, a 20% bonus at online casinos is either a cashback or a reload offer. Here's a short summary of both categories:

Cashback Bonus

Cashback bonuses are the casino's way of letting players win back some of the money they lost during a period or a single session. For example, you activated a 20% up to €200 casino bonus with a 1x wagering requirement. You lost €500 on live roulette, meaning that the casino will let you keep €100 after you wager the said amount once.

Reload Bonus

Reload bonuses are a name for recurring promotions at online casinos, which may be daily, weekly, or monthly. If you take a 20% reload bonus, you are basically activating a simple match deposit bonus. The wagering requirements on these bonuses are similar to welcome bonuses, so they are effectively not more favourable than a simple match deposit; the only good thing about them is that you can always get them anew.

Requirements to Consider Before Activating Casino 20% Bonus

There are various factors to consider before getting a 20 percent bonus. For instance, casino wagering requirements, although usually low for this type of bonus, must be taken into account. Cashback bonuses are mostly wager once, so if you see a casino asking for more than that, we suggest you look further.

Game restrictions are another important aspect: keep in mind that casinos won't treat all your bets the same. Most of the time, only your bets on eligible games will count towards the bonus amount. For example, if you took out a casino bonus of 20% for the live casino but spent some money on slots during that time, you can kiss the cash you lost on slots goodbye.

Another thing to remember is timeframes. Reload and cashback offers are time-limited, so only the money spent during a particular timeframe will count.

Finally, you should always look out for maximum bet limits; if you're playing an active bonus, the casino will absolutely always impose the maximum bet rule, preventing you from winning big money.
