Yeah I did not make it clear. I wanted to say that I prioritize taking troublesome match3s near the bottom of the board over taking an obvious match4 at the top that gives me no followup match5s. Sometimes the said match3 can lead to a cascade match4 or even a match5.
This is related to the concept of board homogeneity, which means a group of gems consists of mostly two colors of adjacent tiers, such as silver and gold, or gold and sack etc. These are usually the hot spot for cascades.
