But when she perceived the truth, the qualm passed away, and she rewarded them handsomely for their ducking; begging, however, that it might not be repeated, and assuring them that she needed no such proof to convince her of their dutiful and faithful loyalty.
But the craving for excitement which was bred and nourished by the continuance of her unnatural position with respect to her husband in some parts of his treatment of her, was threatening to produce a very pernicious effect by leading her to become a gambler.

Some of those ladies whom she admitted to her intimacy were deeply infected with this fatal passion; and one of the most mischievous and intriguing of the whole company, the Princess de Guimenee, introduced a play-table at some of her balls, which she induced Marie Antoinette to attend.

At first the queen took no share in the play; as she had hitherto borne none, or only a formal part, in the gaming which, as we have seen, had long been a recognized feature in court entertainments; but gradually the hope of banishing vexation, if only by the substitution of a heavier care, got dominion over her, and in the autumn of 1776 we find Mercy commenting on her losses at lansquenet and faro, at that time the two most fashionable round games, the stakes at which often rose to a very considerable amount.
Though she continued to indulge in this unhealthy pastime for some time, in Mercy's opinion she never took any real interest in it.

She practiced it only because she wished to pass the time, and to drive away thought; and because the one accomplishment she wanted was the art of refusing.

She even carried her complaisance so far as to allow professed gaming-table keepers to be brought from Paris to manage a faro-bank in her apartments, where the play was often continued long after midnight.
