Single-tile feedback tells you about one slot at a time. Diffle compresses more information into each row. A pill spanning three letters means all three stay adjacent in the final word. A capped block on the left tells you the answer opens with that letter without fixing every position after it.
That extra structure is why diffle rewards planning. You are not only collecting greens. You are assembling rules about order, runs, and banned letters, then testing words that respect the whole set.
