How we verify promo codes: the form, the screenshot, the date

The steps

1. A clean profile

   The scripted browser, Playwright driving Chromium, starts with no cookies, no stored session and no previous visit, from a connection in a country the brand accepts. A code that only works for returning visitors, or only from a partner's link, fails this step by design.

2. The registration form

   The script opens the brand's registration page, finds the promo code field, opens the "I have a promo code" link where the field is folded behind one, and records whether the field exists and where it is. A brand whose code goes in the profile after registration, as at Vavada, is checked there, in a registered account, and the card says so.

3. The code typed in

   The script types the code as printed on the card and waits for the form to respond: a tick, the offer's name, a message, or nothing. The response is recorded as text.

4. The screenshot

   The field with the code in it, and the form's response, are captured as an image and saved with the brand, the code and the date. That file is the evidence, and it is the one shown on this page and the bonus page.

5. The terms, the same day

   The promotion terms are read for the offer behind the code: the spin count, the slot, the multiplier and its base, the cap, the max bet, the expiry, the restricted countries. Each is printed on the card as read, and where a figure is missing the card says not published.

6. The review, where we went further

   For the scored brands the team also read the full terms and the cashier rules, put questions to support about the check and the payout, and matched the licence against the regulator's register; the review records the answers. That is the review's method; the code check above is the bonus card's.
