The Codex of Fortune is adorned with symbols that blend seamlessly with its enigmatic theme:

  • Lower-value symbols: The classic J to A card royals, artistically integrated into the game’s French Art Nouveau aesthetic.
  • Higher-value symbols: A suite of beautifully rendered animals, including lions, turtles, fish, snails, and owls, which bring higher payouts and a deeper immersion into the game’s lore.
