Oracle is an interactive web program that analyzes patterns in a user's left and right arrow key inputs to predict their next keystroke. It is typically correct around 70% of the time, as humans struggle to act randomly. The program records each keystroke, compares the frequency of subsequent left or right inputs after matching four-keystroke sequences, and guesses the more common outcome. A similar approach can be applied to Rock-Paper-Scissors.
