Both PBSKids and Seussville offer "The Cat in the Hat" games to play for free. The games are Flash-based, so there is no software to download or install. PBSKids.org offers the game Invention Engine, Marbelous Marvel Coaster and Gravity-a-Boing-Boing, while Seussville.com offers The Cat in the Hat Balancing Act and The Cat in the Hat Cleans This and That.
To play the games on both sites, players use a combination of mouse clicks and keys on the keyboard, including arrow keys and space bars, to move the characters, collect objects and progress from level to level. The games are ideal for most children under 12 with some games designed for preschoolers.
