Are you bothered by boring train rides or the long wait at the doctor's? Are you looking for fun? Then QuadChallenge is the right game for you! QuadChallenge is a game of skill with absolutely addictive qualities, combining dexterity, speed and pattern matching.

Your task is to delete tiles from the playing field by building rectangles with same-colored corner tiles with a single dragging motion. But there's a catch: you only have 4 minutes to get as many points as possible. If you've deleted the tiles new tiles appear in the gap randomly.
