Nanaro no Go

Nanaro no Go is a children's version of Go aimed primarily at children and is a step up from よんろのご: IGO puzzle. It is based on the Japanese Go Association's beginner method. Nanaro is Japanese for "seven lines". And so Nanaro no Go is played on a 7x7 grid. Each player tries to surround carrots (located at each intersection) with their horses (stones). Iyama Yūta, the first Go player to hold all the seven major Japanese Go titles simultaneously recommended the game as "The perfect introduction to Go".
