  1. There is no prohibition, per se, against gambling. However, it is clear that it is not recommended.

    Having said that the Sages rule that gamblers are invalid as witnesses in a Jewish court. However, there is a difference of opinion as to why gamblers are invalid witnesses. According to one opinion, someone who wins a bet is like a thief, because he collects prize money that he didn’t ‘earn’ and to which he has no true legal claim. According to another opinion, only a professional gamester who has no other source of income is invalid as a witness. His integrity is  suspect because he spends his day in pursuits which contribute nothing to society. According to this opinion, someone who gambles only part-time can be a valid witness, provided he is involved in some productive activity.
