Block Color Puzzle Blast

You drag colored blocks onto a grid and try to complete full rows or clusters so they clear, the same core idea as a lot of block-fitting puzzles but with color-matching layered on top of shape-fitting. Planning two or three moves ahead matters here, since dropping a block in the wrong spot can wall off a whole section of the board. It rewards patience over speed, there's no clock, so a cluttered board is a planning problem rather than an emergency.
