Best Casino Welcome Bonus 2025
Welcome Bonuses, or sign-up bonuses, are a form of casino bonus that is given out to new players who join an online gambling site and are used to attract and reward the players. This is one of the biggest advantages casinos have over their land-based siblings, as these don’t normally reward new players. A sign up bonus can be a great way to get players to enjoy a casino initially, without having to deposit vast sums of cash into their casino accounts.

Types of Welcome Bonus
Understanding the various free spins offers can help you select the best ones.
Deposit Match Bonus
The first way a casino will make up its welcome bonus is with a deposit match bonus. As the name suggests, this is when the casino will match a deposit made by the player. This is normally the first part of a welcome bonus.
A casino will normally say something like 100% Bonus up to $1000, meaning that a player can deposit up to $1000 and they’ll receive another $1000 to play with, doubling the amount in their account. If you deposit $700, you’ll receive an additional $700, however, if you deposit $1500 into your account, you’ll still only receive $1000 extra.
Percentage Deposit Bonus
The bulk of the welcome bonus will be made up of percentage deposit bonuses. These bonuses work almost identically to the deposit match bonus mentioned above. However, the casino won’t match your deposits, rather giving you a percentage as a bonus.
The percentage can vary, but the most common variants are 75%, 50%, and 25%. In some cases, casinos can even offer over 100%, like 200% or more, doubling your initial deposit with the casino.
Percentage Deposit Bonuses would look like this:
- 75% Deposit Bonus up to $200
- 50% Deposit Bonus up to $100
Free Spins
Another bonus type that many casinos love to use these days is free spins. Typically, these will be given away when a player makes their first deposit. Normally a gambling site will specify which online slots these free spins can be used on, and this also helps an Internet casino to promote new slot games.
Tips for choosing a Welcome Bonus
Because almost all casinos will offer a welcome bonus to new players, there are hundreds to choose from. This can make choosing a casino site an even more daunting task. Below are some helpful hints that will hopefully help players choose the best sign up bonus that will suit their needs.
- In most cases, bigger is better. Players should keep an eye out for the welcome bonuses that offer the most in terms of monetary value and free spins. However, don’t simply go out and choose the biggest bonus, as there can be other factors.
- Pay attention to the wagering requirements. Big welcome bonuses can sometimes come with even bigger wagering requirements.
- Always try to deposit the maximum you can on each deposit. If the sign-up bonus says 100% up to $100, try and deposit the $100, so you don’t lose out on any of the bonus.
- Nothing is stopping you from claiming multiple welcome bonuses. However, you’ll need to join a few casinos to do so.
- Find one that meets your online gambling needs. If you’re a player who enjoys table games, a welcome casino bonus that gives you 100s of free spins for slot games might not be worth it for you.4

Welcome Bonus Wagering Requirements
When it comes to welcome bonuses, you need to pay attention to the wagering requirements. Wagering requirements have been put in place by casinos to protect themselves from players who would abuse the system. Imagine if a player could claim a $1000 bonus and then simply cash it out and never return to the casino. They’d all go out of business tomorrow.
This is where the wagering requirement comes in. In essence, it will ensure a player needs to wager the bonus a certain number of times before the bonus can be cashed out. In most cases, the wagering requirement will be around 40x, but it can be higher or lower.
If you claim a $100 bonus fund with a 40x wagering requirement, it will mean that a player will have to wager $4000 before they can cash out that deposit. Players will also need to keep in mind that some games are more towards the wagering requirement than others. Online slots will count 100%, but some table games may only count 10%.
Players need to understand what terms they’re accepting before claiming a sign up bonus. In many cases, when you hear about a player calling a casino a fraud it is often because they accepted the welcome bonus amount without knowing the terms and conditions.
