Kostas Oikonomou — Payments Editor

Kostas Oikonomou specialises in analysing the terms and conditions of online casinos for Greece players as part of the Leonbet editorial team.

How the reviews are made

The analysis is built on primary sources only: official operator documentation, the regulator's licence record, and the live terms published by the casino.

Numbers for bonuses, wagering and limits are verified against the official terms; a figure that cannot be confirmed is left out, never guessed.

When an offer changes, the affected pages are updated so the stated conditions match what the operator currently shows.

One principle governs the work — publish only what can be verified against a primary source.

Editorial responsibility

The remit is fact-checking and maintaining up-to-date information on payments, bonuses and licence status.
