Casino Welcome Bonus: Find the Best Casino Sign Up Bonus Offers for November 2025

What is an online casino bonus for new players?

A welcome bonus is often the first type of promotion that is given to a new player. Depending on where you are betting from or which online casino you pick, there are a variety of different forms of welcome bonuses and how much value they provide.

More often than not, these promotions require you to make a first deposit of a specific amount, usually around $10. The most common type of online casino sign-up bonus is a match deposit bonus, where your first deposit is matched by a certain percentage - 50%, 100%, 200%, and so on.

You might also be awarded a welcome package that can consist of several elements at minimum deposit casinos, such as a match deposit bonus, bonus spins, and a casino credit bonus. Here’s a quick example of how this could look:

• 100% match deposit bonus, up to $1,000 + 50 bonus spins + $20 casino bonus credits

Once you have retrieved the casino bonus, you can put it to good use in whichever way you like. Of course, there might be a few terms and conditions to consider, such as restricted games and wagering requirements before you can withdraw your winnings. Plus you will have to remember to follow responsible gambling practices at all times to ensure that your gameplay doesn’t get out of hand.

Online casino sign-up bonus terms and conditions explained

Once you have found the perfect welcome bonus for you, you must consider whether or not it is worth the time and effort. This can be done by clarifying the terms and conditions of the offer. Every welcome bonus has a set of terms and conditions attached which you will need to meet before claiming the bonus or being able to withdraw your winnings.

Here’s a list of the standard terms and conditions that you are likely to encounter:

1. Eligibility

An online casino will usually enforce a rule that you must be a new customer who has recently signed up. Some casino brands will allow customers to claim an offer further down the line provided that they have not deposited any funds into their account or claimed a previous welcome bonus.

2. Minimum deposit

Before you can collect your welcome bonus, you will most likely need to make a deposit into your casino balance. The minimum amount is usually very low and between $10 - $20. But sometimes you might come across exceptionally low deposit requirements of just $5.

3. Location

Welcome bonuses can often change depending on where you are betting from. Regardless of whether or not the brand is operating in your area, the bonus might be different. For example, a deposit bonus might be 100% up to $250 in selected states but reduced to $100 in other states.

4. Expiry periods

Most sign-up bonuses are only valid within a certain timeframe. For example, you might only be able to claim the offer within the first 30 days. Once you have collected the bonus, you are usually given a specific number of days to use it too.

5. Wagering requirements

This bonus-related term dictates the number of times that you must wager the bonus funds before you can request a withdrawal. For instance, let’s say you claim a $100 sign-up bonus that has a 35x wagering requirement. You will need to wager $3,500 before you can cash out.

6. Payment option restrictions

Some online casinos will put restrictions on which payment methods you can use on your first deposit when claiming a welcome bonus. The most common restrictions are with e-wallets such as Skrill and Neteller.
