    "Overall Thirty One is deceptively addictive – it's another one of those 'gotta play just one more round' games that I personally love."

    "A different kind of card game that requires a bit of strategy combined with the mind games of poker - challenging, unpredictable and addictive!"

    "Thirty One is particularly fun because it feels familiar but is truly unique. All in all, it's a fun game, and well worth a play."

    "It's a very addicting game and it's very easy to use. 5/5"
