Most Nigerian bettors register on a phone, not a laptop, and the Promotion Code field behaves slightly differently across bet9ja promotion code's interfaces. The code is YOHAIG on every one of them.

Bet9ja Mobile

The full mobile site is what most people see on a modern Android or iPhone. Scroll down past the password confirmation and the Promotion Code box is there, marked optional. It is easy to miss because the Register button is visible before you reach it.

The lightweight version

Old Mobile exists for feature phones and areas with weak data coverage. It loads faster and uses far less data, which is why it remains widely used across Nigeria.

The sign-up flow is more compact. YOHAIG goes in the same field, which on this interface sits closer to the top of the form. If you are registering on Old Mobile, enter YOHAIG before submitting, exactly as you would on the full site.

The Bet9ja app

Registering inside the app follows the same sequence as mobile web. The Promotion bet9ja promo code field appears in the same position, and YOHAIG applies identically. If you have already installed the app but not registered, you can still enter the code at that point.

Practical guidance

• 
  
• On 4G with a recent handset, the standard mobile site is the better experience.
• 
  
• Where data is limited, Old Mobile costs a fraction of the bandwidth.
• 
  
• Registering for the first time: any of them works, provided you enter YOHAIG.
