Mathematical sequences are often used in video game leveling systems to create a sense of gradual progression and balance. The Fibonacci sequence often appears in nature, art, and architecture due to its unique mathematical properties. In this system, the experience points (XP) or required levels increase according to the Fibonacci numbers (1, 1, 2, 3, 5, 8, 13, 21, etc.), which creates a smooth, non-linear difficulty curve. This ensures that earlier levels are easier to reach, while later levels require more effort, making the player’s progression feel rewarding without becoming too overwhelming.
