Unfortunately both Go and Gobang are played on a 19 x 19 square board, which is 361 squares

Not according to Chambers !

[Aquagility]

Checkers -- Britannica Concise Encyclopedia - The ...Checkers, board game. ... which players attempt to move a number of pieces from one corner of a square board containing 256 squares

[ulysses100]

....you are right k, that's what it says in Chambers ----- but on Googling the rules of both games they are both played on a Go board of 361 squares !

[Aquagility]

.....or indeed 14x14=196! On the other hand, I know none of my suggestions begin with G.

[smouse]

I did say starts with 'G' but didnt say it had to have six letters so will go with GOBANG
Thanks all of you

For info, a GO board is 19x19 lines = 18x18 squares--I have one.
