A promotion or bonus code is a series of letters or numbers that you enter into a special field when logging into your online casino account to claim a promotion, bonus, or other special offer. Much like a coupon code for products or services, a promotion or bonus code allows you to apply free play credits, free play money, and other specials to your deposit account. Other specials, like deposit-matches, may have promotion codes that, when entered, apply a note to your account that tracks your depositing (or wagering, winning, or play) toward reaching the requirements for the bonus over a certain time period.
There are many ways to receive bonus or promotion codes, including through:
Reviews of online casinos and their bonuses
Special offers on an online casino’s site
Newsletters and other mailings as a site member or member of an online casino’s loyalty program
