CineLinkr is a free daily puzzle for film lovers. 16 movies appear on screen and your job is to find four hidden groups of four. They might share a director, a genre, a plot device, or something sneakier hiding in the titles. You get four mistakes. No account, no ads, nothing to install. Play once a day, feel smart or get humbled. There's a sister site called PixelLinkr that runs the same format for video games.
