["Understanding Multiplication with Non-Prime Numbers in Roll-Based Games: The Case of 3×3 = 9 and Parity in Non-Prime Die Rolls", "When rolling dice in games—especially in strategy, role-playing, or probabilistic systems—players often rely on intuitive math to calculate outcomes. A frequent question arises: What’s the total number of combinations when rolling four (or six) 3-sided dice?
