The Game of Life and How to Play It by Florence Scovel Shinn is a self-help book promoting the idea that life is a game governed by spiritual laws. Shinn emphasizes the power of positive thinking, the importance of aligning oneself with divine will, and the impact of words and thoughts on shaping reality. The book details techniques for improving one's life through methods such as affirmations, denials, and the practice of non-resistance, all based on the principle of faith and the inherent goodness of the divine.

The book concludes by highlighting the importance of love, intuition, and forgiveness as keys to unlocking one's true potential and divine design.
