If fish still have letters in when Tux swallows them, then his belly gets sore and the player loses a life. When the player presses the matching key, or types the correct word, Tux will locate himself at the bottom of the screen ready to eat the fish. Each fish has a letter or a word written on it. In the first game, fish fall from the sky. The language can be selected in the program's main menu, although users will find that not every element of the game is translated – this might be frustrating to those who don't read English.

Tux Typing supports a wide range of languages, including Armenian, Bokmal, Brazilian Portuguese, Catalan, Czech, Danish, German, English, Euskera, French, Spanish, Greek, Jamaican, Lithuanian, Nepalese, Russian, Swedish, Swahili and even a few smaller languages you might not expect to find. It was developed by Tux4Kids, a company that develops high-quality software for children. The software is available as a free download on a variety of platforms including Mac OS X, Microsoft Windows (Vista and up to Windows 10), and Linux (Ubuntu).
