Q&A With Samuel

How do you start verifying a new online lottery platform?

I begin with a structured checklist covering licensing, company details, and payment methods like Apple Pay, PayPal, and Boku. I also prioritise responsible gaming measures. After that, I test account creation and key platform features to confirm the claims made on the site.

How do you handle conflicting information during verification?

I document the discrepancy carefully, capture evidence, and contact the platform for clarification. If the issue remains unresolved, I clearly note it so readers understand the situation before they decide to play.

What sources do you cross-check during fact-checking?

I rely on official regulator databases, operator disclosures, independent audit reports, and direct platform testing. Primary sources always come first, supported by additional verification where needed to ensure UK players receive accurate data.

What principle guides your work the most?

Accuracy and transparency. Every claim should be verified, sources should be clear, and readers should always understand how conclusions were reached regarding any lottery site or software provider like Evolution Gaming or Playtech.
