Amanda's Letter Lotto provides several levels of play. For young toddlers (18-30 months) it allows then to push keys that change the colors and symbols on the screen and get the computer to make some sounds. As your kids grow older they progress to locating specific keys and learning multiple key combinations. At the most difficult level of play you need to correctly pick five secret letters to win Letter Lotto. It works just like a miniature version of the Lotto games run by many states. Minimum Requirements: Mono, CGA, EGA or VGA.
