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. After that, I test account creation and key platform features, specifically checking if local payment options like MTN Mobile Money and Airtel Money are handled securely 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 sign up or 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 players in Rwanda receive the most accurate data.

What principle guides your work the most?

Accuracy and transparency are my top priorities. Every claim should be verified, sources should be clear, and readers should always understand how conclusions were reached regarding the safety and fairness of a platform.
