I think everyone agrees that video poker is a game of chance. The difference between playing VP and playing a scratcher is that with a scratcher it is predetermined whether or not you will have a winner. In video poker, you have choices which can make you win or if you choose the wrong cards, you could give up a winner.
I don't know of any scratchers that let you choose "draws." I have to agree that it's really a meaningless comparison to video poker.
Scratchers are more like watching someone else roll two dice while you are betting at a craps table. You have to "live" with the result of the roll. But if you have the chance to roll the dice yourself, you have the chance to influence the roll (however slim that might be) to have the dice give you a winning combination.
I thought it was interesting that in the original post slingshot wrote "the scratch-off that was so unpopular (according to him) because buyers had been purchasing them all over town and no one was winning." Perhaps this was a "long shot" scratcher and not like here in California with the 1:3.5 odds?? In which case we have to ask, was his friend betting on "red" because the result board at roulette was showing a long run of "black"??
