Corner the Lady

Corner the Lady © 1977 SR-52 Users Club.

A game invented around 1960 also known as Queens, or for its more abstract form of Wythoff's Nim. This implementation allows the player to play it on a programmable calculator. The computer and player control a queen (chess piece) on a grid with the restriction that it can only move south, south-west or south. The player and computer take turns in moving the queen and whoever corners it at the bottom wins the game.
