Where can I find description of the games on the color Thumby?

Usually the description or display is in the TinyCircuits Thumby product. The "Play & program" section and API documentation, MicroPython / Blockly programming guide are probably the information you need.

Thumby Arcade / Code Editor is the most reliable place to view game listings and descriptions provided by developers.
