+ * Game of Diamond
+ * <p>
+ * Based on the BASIC game of Diamond here
+ * https://github.com/coding-horror/basic-computer-games/blob/main/32%20Diamond/diamond.bas
+ * <p>
+ * Note:  The idea was to create a version of the 1970's BASIC game in Java, without introducing
+ * new features - no additional text, error checking, etc has been added.
+ *
