The Casino Oxygen Urban Legend
This particular urban legend - that casinos pump oxygen into the rooms to keep people happy and gambling - is representative of a whole sub-set of Urban Legends that revolve around casinos and poker rooms. In most of these legends the Average Joe is the loser, one way or the other, and the House is the winner. While this is often the case it is due to the built in edge the House has over the patrons, and not due to any machinations or malignant forces. Yet the legends persist, perhaps as a way to explain to the gambler why he or she keeps losing in the long run, providing a handy excuse to keep on gambling regardless.
In most cases the names, currencies, and locations of the casinos featured in these Urban Legends are interchangeable. In Atlantic City it is rumoured that the computer chips of some slot machines are faulty thanks to the holy water poured in the slots by some patrons. In Las Vegas slot machines only pay out at the whim of a man in a control room, watching the scene with video cameras and determining who is worthy- according to the legend.

It is hard to imagine the idea that casinos pump oxygen or anything at all into the air systems to keep people gambling was created out of whole cloth- surely there must have been some precedent? Some believe the idea came from a time that something WAS pumped into the air systems in one casino. A researcher in Atlantic City once got permission to pump different scents into the casino to study what affect it might have on gamblers behaviour (the results were inconclusive.)

The Megabucks Legend
Megabucks is a slot machine system that is linked across many casinos. Starting with a huge jackpot (in the millions), the Megabucks grows and grows until someone finally “hits it.” This is, as one could imagine, a very popular game, and one that has fostered many urban legends of its own. Most centre around someone who hits the jackpot, but can’t collect because of a mistake or ineligibility.
Final Thoughts
In the case of the Megabucks, there was some truth to the legends. One player in 2001 got distracted when he was putting in the three coins needed to qualify for the jackpot. The game still runs on less, but three is required to hit. He only put in two—and sure enough, hit the jackpot. He was one dollar short of a more than three million dollar prize.
