My mistake. The reason for the dispute should be obvious. The sentence that I removed is indicative of the overall tone of the rest of the article: "It is best to stay clear of this game and those running it." Wikipedia does not give gambling advice to begin with, but the tone issue is much deeper set. A few more examples:
"the operators...can be dangerous if provoked."
"the man perpetrating the swindle"
"if played fairly, which it never is"
"players (victims)" multiple instances of this
"nearly all the persons standing around the game work for the operator"
"Shills are normally rather easy to spot: they win."
"Amazingly, today, the shell game swindle is still performed on the unwary in larger cities."

The whole text needs surgery, not just these examples. Original research means that these alleged facts are not cited to any source, nor could many of them be. What source would you cite, for example, to prove that the game is never played fairly? This article needs to be cleaned up to only state the facts about the shell game, as they can be cited to reliable sources, and in a manner which does not take sides between those who play the game and its proprietors.
