Frequently asked Questions


Every online operator has a sign up bonus (or welcome bonus) which new players are welcome to claim, usually in the form of a first deposit bonus promotion. Some casinos may offer players a small no deposit bonus or free spins to try the casino games for free, but the best casino offers come from the sign up (or welcome) bonus.

The welcome bonus at the casino is usually a match deposit bonus up to a certain percentage, but at many casinos, players can also get a batch of free spins on top of the bonus.

It’s also smart to use the welcome bonus if you’re a new player at the casino. This bonus will help you boost your starting balance, especially if you’re playing with a limited budget. This is why all players agree that a good up bonus is the best casino deposit bonus there is.


A match deposit bonus is a bonus amount which is awarded in percentage to your deposit amount. For example, some casino may offer a 100% match deposit bonus up to €100 for making a deposit at the casino. This means that if you deposit €10 the casino will give you another free €10 to play with.

The up to €100 value marks the maximum amount of bonus money you can receive on top of your deposit. In this case, you will need to deposit a maximum of €100 in order to get the maximum €100 in bonus money from the casino.

The match deposit bonus can vary in percentage from casino to casino but is always awarded only when you make a deposit at the casino. For some players this may not seem like an attractive offer and they would prefer some free bonus without a deposit required.


Used as a marketing strategy to allow new customers get a taste of the games, no deposit bonus offers usually have a value of between €5 and €20. As these bonuses have no strings attached, it gives you a chance to see what you’ll get once you decide to deposit.

The first thing you need to know about no-deposit bonuses is that if you are lucky enough to win using this bonus money, many casinos will only let you withdraw your winnings. Only a few will allow you to withdraw the bonus amount and the winnings.

Furthermore, in almost all cases no-deposit bonuses will have very high wagering requirements (sometimes referred to as play through requirements). In many cases the bonuses need to be wagered around 50 times before you are eligible to withdraw any winnings. On top of that, it’s possible your favorite game won’t count towards the wagering requirements. The bottom line is: read the terms and conditions. Nowadays true no deposit bonuses are quite a rarity and have been phased out in favor of deposit bonuses and free spins.


Most online casinos don’t stop rewarding you after the first deposit, but let you qualify for a bonus on subsequent deposits too. This means that the casino will credit your account with a certain percentage of your deposit. Not all gambling websites offer bonuses on redeposit, and, usually they are lower than the first deposit ones. Others offer reload bonuses on a certain day of the week, or if you achieve a specified number of loyalty points. There are also some common caveats to reload bonus such as the payment method you use, time restrictions, or a limited number of qualifying games. Always read the terms and conditions.


Another type of online casino bonuses is free spins. They are used to reward both new and existing players. There are generally two types of free spins: those offered as a bonus for a deposit, and those for which no deposit is required. Sometimes, free spins are part of a bigger package: a deposit can be rewarded with both match bonus and free spins. Often, free spins offers are restricted to a particular slot game, or limited group of titles, but this will be stated clearly in the promotional materials. In the case of free spins, you will have to play-through the winnings you make from any free spins X number of times before the winnings are cashable.


Although different than the other types of bonuses, loyalty points are yet another rewarding strategy online casinos use. Loyalty – or comp – points are usually awarded based on the amount of cash a player wagers. For instance, for a bet of €10, you can get 1 loyalty point, no matter if you win or lose. When you have amassed enough points, you can convert them back in to money, or exchange them for prizes. If you are considered a VIP player, these comp points will have a higher exchange value than if you are a newbie.


Less common than the other types of casino offers, a cash back bonus is sometimes given to players based on the money they wagered.


Another marketing technique, refer a friend bonus is offered when you recommend the respective online casino to a friend, and they sign up and starts playing. The value of these bonuses differs from one gambling site to another. Usually the sums involved are around €30-€50 and like all the other bonuses you will need to play-through or clear the bonus in order to unlock it.


When the first generation of mobile casinos were launched, casino sites would often present mobile specific welcome bonuses for players who came through and registered and deposited via the mobile site. Nowadays with mobile ubiquitous and over 50% of players reaching a casino via app or mobile responsive site these have almost been phased out – with the welcome bonuses presented on the smaller screen identical to those on desktop.


The moment you get confirmed as a VIP customer of your favorite online casino, the array of bonuses instantly diversifies: cash rewards, free spins, monthly loyalty bonuses, access to special features and unique games, and even real-world events. Some VIP programs are just the higher levels locked into the loyalty points program whilst others are run on invitational lines to select high rollers.
