Your method of breaking down the 6x6 matrix into manageable 6x3 sections and using loops to calculate hourglass sums is a smart, structured solution—especially for fixed sizes. It's similar to how in Bowmasters, you might focus on specific strategies to collect gems efficiently within a known game mode or map. However, just like your matrix approach might not scale well for NxM matrices, a rigid strategy in Bowmasters might not adapt well across different challenges or updates. Flexibility is key in both cases for long-term success and efficiency.
