It is generally accepted that gambling is NOT a christian thing. So much so, that JWs are not supposed to play the lottery, make bets or wagers, play Poker, even playing poker with fake money is frowned on!
Why?
Take bets/wagers for example.
Samson did it! (Judges 14:12-13) Then Samson said to them: "Let me, please, propound a riddle to YOU. If YOU will without fail tell it to me during the seven days of the banquet and YOU do solve it, I shall in that case have to give YOU thirty undergarments and thirty outfits of clothing. 13 But if YOU are unable to tell it to me, YOU yourselves also must give me thirty undergarments and thirty outfits of clothing." At this they said to him: "Do propound your riddle, and let us hear it."
What is that, besides a wager?
How about casting lots?
This takes place all through the bible, as a way of choosing a course of action, or in order to win stuff. The practise is never condemned, and can presumably still be used today.
The fact that the casting of lots correctly pointed to Jonah, indicates that God had a hand in it, and thus, approved of the action. (Off topic, is this so much different from tarot cards or palm reading?)
Then there's the fact that the land was distibuted to the isrealites by casting lots:(Numbers 26:52-56) After that Jehovah spoke to Moses, saying: ...56 By the determination of the lot one’s inheritance should be apportioned between the many and the few.”
So there are at least three scriptures that are pro-gambling. What scriptures are anti-gambling?
