Kurushima Kinai

Kurushima Kinai (久留島 喜内?, died January 9, 1757),[1] also known as Kurushima Yoshita[2] and Kurushima Yoshihiro (久留島 喜内?),[3] was a Japanese mathematician in the Edo period.[4]

The Japanese board game of shogi attracted Kurushima's interest; and he was recognized in his own time as a master player.[5] Among shogi players, he continues today to be well known for seven "puzzle ring" gambits with subsequent sequenced maneuvers -- including the "silver puzzle ring."[6]

In his lifetime, he was recognized among the most prominent intellectuals. His mathematical gift was highly esteemed.[7] Kurushima, like most of his contemporaries, was very interested in the mathematical problems involved in "magic squares."[8]
