FreeCell's origins may date back even further to 1945 and to a Scandinavian game called Napoleon in St. Helena (not the solitaire game Napoleon at St Helena, also known as Forty Thieves). Paul Alfille changed Baker's Game by making cards build according to alternate colors, thus creating FreeCell. He implemented the first computerised version as a medical student at the University of Illinois, in the TUTOR programming language for the PLATO educational computer system in 1978.
Alfille was able to display easily recognizable graphical images of playing cards on the 512 × 512 monochrome display on the PLATO systems. This original FreeCell environment allowed games with 4–10 columns and 1–10 cells in addition to the standard 8 × 4 game. For each variant, the program stored a ranked list of the players with the longest winning streaks. There was also a tournament system that allowed people to compete to win difficult hand-picked deals. Paul Alfille described this early FreeCell environment in more detail in an interview from 2000.
