Expert Insights: 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 responsible gaming measures. I specifically look for localized payment methods such as Opaywallet, Verve, and PalmPay Push to ensure they work seamlessly. 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 Nigerian players understand the situation before they decide to sign up.

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 of software integrity from providers like SmartSoft Gaming and Betgames where needed.

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 the safety of a platform.
