About Screw Tile GameScrew Tile is a timed 35-stage screw sorting game. Remove screws from the puzzle into the 7 holder spots at the bottom of the screen. Whenever you have matched 3 identically colored screws in the holding area the set of 3 is cleared. Keep removing screws until all have been removed, and finish before the timer runs out to advance to the next level. As you advance through the game the levels grow more complex with layering depth and more screws to remove. You can only remove screws which are fully exposed. Tiles containing paritally covered screws have a gray overlay color. This is a JavaScript web application which uses cross-platform mobile-friendly HTML.
