3 lines flash games

You control a cursor that places colored blocks onto a grid. The goal is to connect three or more blocks of the same color in a straight line, either horizontally, vertically, or diagonally. When you form a line, those blocks vanish. New blocks fall from the top to fill the empty spaces, sometimes creating chain reactions. The game moves at a steady pace, but the grid fills up quickly if you aren't planning your moves. It feels like a quiet, focused race against a slowly rising tide.
