Best Online Casino Bonus [June 2025]

by Alex Thomas | The Gamble Times, updated 17th of June, 2025.

TL;DR
We all know the best way to kickstart any new casino experience is with a little help or freebies before or during your first deposit. Our team put together a list of some of the best no deposit, exclusive first deposit and reload bonuses out there on a select few online casinos. But we will not only list the bonuses, but we will also provide you with our view of the online casino, what we noticed, and what we would recommend. Let’s get right into it.

Online Casino Bonus Introduction

Before we dive into the bonuses and online casinos, we thought a little refresher course on what’s what would be useful to any new players reading this. We will cover the basic online casino bonus terminology, give you hints on where to find more information, and what to pay attention to. There are plenty of tricks online casinos use to try and confuse you; however, if you follow our guide and pay attention, nothing will get in your way.

No Deposit Bonus

A no deposit bonus is exactly what the name says: a bonus you get without having to put down any money. It’s the casino’s way of letting you take their platform for a test drive. You usually get a small amount of bonus cash (like €10 or €20) or a handful of free spins just for signing up. No strings? Not quite. But it is a chance to try out real-money games without dipping into your wallet, and that’s always a plus for curious players or cautious newcomers.

That said, no deposit bonuses come with fine print, something you should read beforehand. Most of the time, these offers have high wagering requirements, meaning you’ll need to play through your bonus money many times before you can cash out any winnings. Some of them also lock their withdrawals behind a first deposit, with a maximum cashout being 5x the deposit amount.

It may be tempting to create multiple accounts in the hope of hitting at least one no-deposit bonus, but please be aware that online casinos have a strict ‘one account per person’ rule. So even if you do end up winning, there is a high chance your account (and winnings) will be void if you break the rules. Check out some other common mistakes players make at online casinos.

First Deposit Bonus

A first deposit bonus is the main welcome gift most online casinos offer when you make your first real-money deposit. It’s usually a match bonus, something like “100% up to €500”, which means if you deposit €100, the casino gives you another €100 to play with. It’s a solid way to increase your bankroll right out of the gate, giving you more time and room to explore the casino games without extra risk.

But just like with no deposit offers, the devil’s in the details. First deposit bonuses nearly always come with wagering requirements, often 30x, 40x, or higher, meaning you’ll need to bet the bonus amount (and sometimes your deposit too) multiple times before you can withdraw any winnings. Some casinos also cap how much you can win or limit the eligible games. Before jumping in, check the terms carefully. A big headline number looks great, but what matters is how realistic it is to cash out.

From my experience, it’s easy to spot the wagering requirements by simply looking at the amounts given. 100% up to 300 EUR? That’s usually a close to no wagering offer. 1000% up to 1.000 EUR? I would bet my money on it being a high wagering requirement (they suck!). It’s hard to see at first, so what I did at the start is, I always checked the Terms and Conditions or even went on live chat and asked.

Reload Bonus

This is the only bonus on the list that is not exclusive to new players. Think of it as a loyalty reward, something you can claim with each deposit after you have claimed the welcome bonus. It’s the casino’s way of saying, “Hey, thanks for sticking around!” These bonuses usually come as a percentage match on your deposit, like 50% up to €200, and sometimes include free spins too. You’ll often see them tied to specific days (like “Reload Thursdays”) or as part of weekend promos, VIP perks, or ongoing promotions.

The catch? Yes, you guessed it. Wagering requirements (usually!). The conditions based on this bonus aren’t always as tough as the online casino already has you onboard. Just remember, only claim a reload bonus if the terms are fair and you really want to play more. If not, stay away and don’t chase a bonus that might not pay off.

Is A Bonus Fair?

When examining online casinos and their bonuses, we always check a few things, just to safeguard against anything later on. The first one, I’m sure you’ve guessed it, is wagering requirements. I’m not a fan of 40x wagering of my deposit and bonus amount, so I try to stay away from those. In my opinion, a fair amount is around 20, with no wagering being an absolute goldmine. Anything above that? It’s still playable, but the odds start working against you.

Next up: game restrictions, maximum bets, and win limits. All of those are usually present when you claim a bonus. While not impossible to beat (like we cover in our 2025 guide), they do limit how you play. In my experience, the limits for no wager bonuses usually move around a maximum bet of 3 EUR per spin (so feature buys are excluded) and with a win limit of 5x your initial deposit amount. Game restrictions, on the other hand, are usually based on your location as well as slot volatility and hit frequency.

Recently, what we have been seeing is that online casinos tend to shorten their expiry times and exclude certain payment methods from their bonus list. Something we recommend you check with the live chat agents before claiming a bonus. Overall, a fair bonus should give you enough time and freedom to play your favorite games, without stressing about wagering requirements and time limits.
