What is a bonus code?
Last updated:
A bonus code (also called a promo code) is a string of text that you enter during registration or when making a deposit to activate a specific promotional offer. Not all bonuses require a code, but many do, particularly exclusive deals from affiliate partners or email campaigns.
Where to find bonus codes
Casinos often distribute exclusive codes through affiliate websites, email newsletters, and social media promotions. These codes can unlock offers that aren’t available through the standard sign-up flow. Comparison sites frequently list codes for various casinos alongside their bonus reviews.
How to use a bonus code
The code entry field is usually shown during the registration process or on the cashier/deposit page. Enter the code exactly as written, including any specific capitalization, before completing your deposit. If you miss the window for entering the code, contact customer support as they can sometimes apply the offer manually before it expires.
Ben Barber got into the gambling industry through the poker rooms of London in the early 2000s. After building up a solid grounding in casino, sports betting and poker, he made the move to Malta where he spent close to a decade writing for some of the biggest affiliate networks in the region. A few years ago he relocated to Bali, which shifted his focus toward website strategy and affiliate marketing. The casino side never really left, though. He still writes reviews, how-to guides and in-depth pieces on everything from slots and live dealer tables to crypto casinos and sweepstakes sites. His approach is fact-first: help players understand how online gambling actually works before they deposit a cent.
