Once we’ve completed our checks, we bring everything together into the Casivo rating. Safety and licensing are fundamental, but we also consider bonuses, games, payments, withdrawal speeds, support and usability. Features such as game filters, favourites, recently played games and effective search can make a significant difference when a casino offers thousands of titles. We therefore pay close attention to processing times, not just the estimated time it takes a bank or payment provider to complete the transaction. Where possible, we test withdrawals ourselves and compare the actual experience with the casino’s advertised timeframes. Our experts have carefully tested and reviewed online casinos, trying to find the best ones.
