Hark! Not Dragon, but Dragon doth challenge thy wits, thy choices, and verily, a sprinkle of fortune's favor! By mine own hand, I have crafted four modes of play: the simple, the classic, the ever-changing, and the grand. Each beckons to those brave souls seeking eternal glory. Choose ye the portal that hides not the fearsome dragon, and riches shall be thine! The classic mode is the very foundation of this grand jest! If thou art blessed with keen senses, the favor of Lady Luck, or perchance, a touch of the seer's sight, thou might find thy name etched upon the ChestMaster's scroll of honor. 'Tis a merry test to see how far the winds of chance might carry a soul, or if some possess a gift of foresight so profound, it borders on the mystical. The grand mode is reserved for minds most astute. If thou art of simpler wit, mayhaps thou shouldst stick to the lesser challenges, or mayhaps, refrain from partaking in this jape altogether.
