I gambled quite a bit in my life, but not in quantity of $. Many years ago, my wife and I would go to Vegas (4X) and walk up and down the strip to play at the small casinos. I'd play the $1 blackjack tables just to get over the anxiety of sitting at a table with others.
Then came the video combined with real versions of blackjack, roulette and even craps. My favorite common game to play is the video large-dice bubble-roll craps. From what I have read, there is only one bet in a casino that pays even odds and doesn't have a house edge and it is laying odds in craps.
But my all-time favorite gambling game is hard to find. It costs .25/bet and found it at Luxor and The D casinos. At Luxor they had a camel racing game and The D used horses in theirs. It was plastic animal figures that were on tracks and you placed your bet on the camel/horse number and then they would race around the track.
