I have no intention of reviewing all these systems, which are innumerable and of unequal value: the paroli pure and simple, that artless, violent, doubled stake which leads straight to disaster; the D’Alembert and all its variants; the descending progressions; the differential methods; the montant belge; the parolis intermittents; the snowball; the photographie; the staking of equal amounts on certain groups of figures, which is a Chinese puzzle demanding days of patient observation before it is attacked; and many others which I forget, from the most clear-cut to the most mysterious, which are sold at a high price, to credulous beginners, in sealed envelopes containing what is everybody’s secret and with all or nearly all of which I have become acquainted thanks to the kindness of an erudite player. A detailed account of those most frequently used will be found in D’Albigny’s treatise Les Martingales modernes, in Gaston Vessillier’s Théorie des systèmes géométriques, in Hulmann’s Traité des jeux dits de hasard, in Théo d’Alost’s Théorie scientifique nouvelle des jeux de la roulette, trente-et-quarante, etc., and, above all, in the Revue de Monte Carlo, which has given a system in every issue since the day of its foundation some fifteen years ago.

Whether mystic or transparent, all these methods present more or less the same dangers, being all founded on the quicksands of equilibrium and temporary disturbance. If they are very cautious, the loss is trifling, but the gain is still smaller; if they are bold, the gain is great, but the loss is two or three times greater. The best of them, in order to continue the defence of a moderate stake and of what has already been sacrificed, involve the risking on the cloth, at a given moment, of all the previous winnings, which are soon followed by the sums held in reserve. This is the inevitable revenge of the bank, at which you thought that you were nibbling with impunity, but which suddenly opens wide its jaws, like a blind and drowsy crocodile, and swallows profits and capital at a single gulp.
