A funny fact to know the infamous AYBABTU from Zerowing game 2101 translates to 64 in base 3. Base64 is a group of similar encoding schemes that represent binary data in an ASCII string .... Electronic Mail (PEM) protocol, proposed by RFC 989 in 1987.
Zerowing itself was presented in the 1989 although Toaplan originated in the mid 80's.
