This is the relevant reference from the Books where Urn Game is mentioned.
I make no pronouncements on these matters, but report them as I find them.
Arrive at your own conclusions.
I wish you well,
There were also 'Urn Games', playable for different amounts. In these games, one generally draws marked ostraca from an urn, with one result or another. In one 'Urn Game', even numbers of red and black ostraca are placed in an empty urn. One chooses a color and then, if one draws two ostraca of that color from the urn, one doubles one's money. In such an arrangement the odds are clearly unfavorable to the player who, mathematically, has only one chance in four of winning. But such considerations are often unlikely to deter the zealous gambler.
