He found what he was looking for. Though five of the casino's six wheels produced predictably random results, nine numbers in particular kept showing up on the sixth at a rate far exceeding what natural probability would have indicated. Clearly, the wheel was biased.
The first day's foray against the casino netted him roughly $70,000. By the fourth day his winnings pushed $300,000.

Finally, suspecting a switch, he made a quick survey of the other roulette tables, and the discovery of a certain scratch led him to be reunited with his faithful lady. From there he went on to push his total winnings to $450,000, an astronomical sum for 1873.
In the end the casino prevailed. They had their wheel manufacturer in Paris design a set of movable frets, the metal barriers that separate numbers on the wheel. Each night after closing, the frets would be moved to new locations around the wheel. Playing into the teeth of this, Jaggers went on a two-day losing streak. He finally bowed to the inevitable, escaping with his $325,000 remaining profit. He left Monte Carlo, never to return.
The song "The Man Who Broke The Bank At Monte Carlo" was written the year he died.
