Quatro online casino is the latest from G3 Partner who operate the well regarded Grand Mondial casino. Like it’s predecessor, Quatro uses the industry-leading Microgaming software platform with over 350 casino games available. While I haven’t had a chance to play here myself yet, I know from experience that Grand Mondial pays quickly and has decent support and bearing in mind Quatro uses the same team, it’s likely to be it’s equal. The signup bonus is interesting in that you have a choice of a Freeplay bonus or deposit match bonuses, the first of which is a $200 match as I write. Suitable for European players as the software comes in several different languages, but no Americans are accepted.
