What Is a 300% Casino Bonus?

A 300% casino bonus is a type of deposit bonus that boosts your stake by 300% up to a certain amount (maximum bonus value). In other words, your qualifying deposit will be tripled and given to you as bonus money that you must wager several times to take full advantage of or cash out.

Apart from being a simple match deposit casino bonus, 300% offers are most commonly found among welcome offers, either as part of a welcome package or a standalone sign-up offer.

If not included in the welcome package, a 300% bonus at online casinos will likely be dubbed a high roller bonus, given that these offers involve big bonus amounts and steep wagering requirements.

How 300% Bonus Works

A 300% bonus works like any other matched bonus: you put some money at the cashier and have your funds tripled. Provided you act in respect of minimum and maximum deposit limits, you can now play with augmented funds.

The rest is up to you: you must wager your bonus, taking into account the playthrough requirements and maximum bet (the maximum single wager) and play until you meet all of the conditions.

Once you're done, you can go back to the cashier and cash out your winnings, provided you have won anything but no more than the limit set by the casino (max win).

How to Claim a 300% Casino Bonus - Step-by-Step Guide

Here's how to claim an online casino 300% bonus:

  1. Find a suitable offer.
  2. Sign up at the casino.
  3. Make your first deposit and accept the welcome offer
  4. Start playing with your bonus money.

Variations of 300% Casino Bonus You Can Trigger

No matter what a casino calls it, a 300% bonus is a match-deposit offer. Most commonly, it comes in the following shapes:

300% Casino Bonus

Welcome Bonus

Depending on the casino and how much it's willing to boost your funds, a 300% bonus at a casino of your choice may come in the form of a welcome package or constitute the entire welcome bonus.

If it's part of the welcome package, the casino will boost your first, second, or third deposit by 300% up to a certain bonus value.

On the other hand, the casino may offer only a single deposit welcome bonus of 300%. In that case, your first deposit at the casino gets boosted by 300%, allowing you to enjoy extended playtime.

Highroller Bonus

Another possibility is to receive an offer of 300% bonus as a recurring promotion (reload) for highrollers. In this case, players with heftier wallets and bigger gaming appetite can be offered to have their deposits boosted 300% on a regular basis via highroller bonuses.

Requirements to Consider Before Activating Casino 300% Bonus

This is where the casino's Bonus Terms and Conditions come not only handy, but necessary. Among the things to consider are casino playthrough requirements, bonus duration, bonus value, maximum cashout, and maximum bet.

Wagering requirements is basically the casino telling you how many times you should wager the money. Let's take a look at an example.

Suppose the casino offers a 300% up to €500 for a minimum deposit of €20 and a 30x deposit + bonus playthrough requirement. In that case, it means that for a €100 deposit, you must wager €400 (tripled bonus amount + deposit amount) 30 times over before requesting a cashout.

Also, all casino bonuses have a cashout cap, so if the max cashout is €300, winning more than this amount means giving it back to the casino.

Finally, game restrictions should also be considered because the casino won't count any bet towards wagering; for a casino's 300 bonus, slots and table games don't necessarily need to contribute the same. Online slots commonly contribute 100% to fulfilling playthrough requirements, while table games, for example, contribute much less.
