Toy later worked at University of California, Berkeley where he met Arnold, the lead developer of the curses programming library that Rogue was dependent on to mimic a graphical display.

Toy and Wichman, both students at University of California, Santa Cruz, worked together to create their own text-based game but looked to incorporate elements of procedural generation to create a new experience each time the user played the game. Rogue was inspired by text-based computer games such as the 1971 Star Trek game and Colossal Cave Adventure released in 1976, along with the high fantasy setting from Dungeons & Dragons. Moreover, no game is the same as any previous one, as the dungeon levels, monster encounters, and treasures are procedurally generated for each playthrough. The player must restart with a fresh character as the dead character cannot respawn, or be brought back by reloading from a saved state. Rogue implements permadeath as a design choice to make each action by the player meaningful-should the player-character lose all their health via combat or other means, that player character is dead. Rogue is turn-based, taking place on a square grid represented in ASCII or other fixed character set, allowing players to have time to determine the best move to survive. Along the way, players can collect treasures that can help them offensively or defensively, such as weapons, armor, potions, scrolls, and other magical items. The player character must fend off an array of monsters that roam the dungeons. In Rogue, players control a character as they explore several levels of a dungeon seeking the Amulet of Yendor located in the dungeon's lowest level. Additional ports to modern systems have been made since by other parties using the game's now- open source code.
ROGUE LEGACY CONTROLS SOFTWARE
Design and financially supported by the Epyx software publishers. Commercial ports of the game for a range of personal computers were made by Toy, Wichman, and Jon Lane under the company A.I. It was later included in the Berkeley Software Distribution 4.2 operating system (4.2BSD). Rogue was originally developed around 1980 for Unix-based minicomputer systems as a freely distributed executable.
