View More Welcome Bonuses

Welcome Bonus aka Signup Bonus aka New Player's Bonus is designed for maiden gamblers who are looking for free signup. These bonuses are given away to players to promote initial deposit. Most of the casinos match the first deposit of a player by 100%. Some even go up to 150% or 200%.

The Welcome Bonus comes in two forms: Free Spins and Free Play Bonus. Free Spins can either by utilized on specific slot games or all games offered by an Online Casino. Free Play Bonus is credited to your account in the form of real money and this needs to be utilized within a specified time frame.

Take into account the Bonus terms and conditions pertaining to the following points before signing up and redeeming the bonus:

  • One Real Money Account:

    A player is entitled to claim the Welcome Bonus only against one account. If multiple accounts of a player are detected then the entire bonus amount on all accounts will be canceled.

  • Bonus Code:

    To claim the Welcome Bonus, figure out how an Online Casino handles its promotions. If a “bonus code” is required to avail the offer then you can find the same listed next to the casino in the table. At some online casinos, you have to enter the code in the cashier section and at some casinos, you are required to send the bonus code to the support team. However, many online casinos let you avail the offer without a bonus code.

  • Welcome Bonus Offer Value:

    Every Welcome Bonus comes with a percentage match and the maximum bonus amount.

    For example, Suppose 150% is the percentage of match and the maximum bonus amount equals to $150, the optimum deposit amount would be $100 as you can cash in on the entire 150% bonus amounting to $150 (the upper limit of bonus). Thus, your account would be credited with $100 deposit + $150 bonus = $250.

  • Wagering Requirements:

    A player needs to fulfill the wagering requirement before redeeming the bonus balance.

  • Validity:

    The bonus balance is forfeited after the validity expires. Generally, the validity of a casino bonus offered by an online casino is 30 days. It can vary from casino to casino.

PRO TIP: To calculate the optimum amount pertaining to the first deposit, always take into consideration both percentage of match and maximum bonus amount offered by an online casino.
