StroQ is an addictive puzzle game where you have to flip white and black tiles in order to form rows of the same color with a single stroke of your mouse.
The goal of the game is simple, draw a single continuous line, the stroke, from one square to another. When you run the puzzle (press F5) white and black squares along this line will flip over (white becoming black, and black becoming white). The puzzle is solved when all tiles on the rows are the same color. You can reset a puzzle by pressing the right mouse button or the F4 key.
