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 Revolut, Apple Pay, and Google Pay. 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 in Ireland 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, and independent audit reports from providers like Playtech and Evolution Gaming. Primary sources always come first, supported by direct platform testing and verification of responsible gaming measures.

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. This ensures a fair and safe environment for everyone using our comparison site.
