Like me, you are most likely inclined to believing Sudoku is some kind of an ancient Japanese game. In fact it was created by an American architect Howard Garns.
Garns was born in Connersville, Indiana, and by his teens had moved to Indianapolis with his father, W. H. Garns, an architect. He attended Indianapolis Technical High School (now known as Arsenal Technical High School or Tech High School) and graduated in 1922. He entered the University of Illinois, and received a Bachelor of Science in architectural engineering in 1926.
The game was initially called Number Place and. Number Place gained popularity in Japan in the eighties. Garns dies before Su Doku became popular on the global realm
