Colossal Cave Adventure is an English text-based adventure game developed by Don Woods. It was originally published by Central Computer & Software in 1983, and became a bestseller. It was later ported to many other platforms, and was even translated to many other languages.

It is known for its unique text-based gameplay, as well as for its many memorable quotes and its interesting storyline. The game was also used as the basis for a number of other games, including the famous platformer series.

This version is a translation of Don Woods' 430-point extension of the original Colossal Cave Adventure. It will be the same as the original, except for the changes made for the modern platform.

The original game was created using a text editor, while this version is created using a text-to-speech program. This change made it possible to read the game to the player, allowing them to follow the storyline and to receive useful information, such as when they can find a treasure and how to get to the treasure.

The game is set in a maze-like passageway. The player is a little boy who must find a way to reach the treasure, which is hidden in the maze. Along the way, he will encounter various obstacles. The treasure is a golden key that will help him unlock a door to reach the exit.
