Go (game)
Notation and recording games

Go games are recorded with a simple coordinate system. This is comparable to algebraic chess notation, except that Go stones do not move and thus require only one coordinate per turn. Coordinate systems include purely numerical (4–4 point), hybrid (K3), and purely alphabetical. The Smart Game Format uses alphabetical coordinates internally, but most editors represent the board with hybrid coordinates as this reduces confusion.

Alternatively, the game record can also be noted by writing the successive moves on a diagram, where odd numbers mean black stones, even numbers mean white stones (or conversely when playing with a handicap), and a notation like "25=22" in the margin means that the 25th stone was played at the same location as the 22nd one, which had been captured in the meantime.

The Japanese word kifu is sometimes used to refer to a game record.

In Unicode, Go stones can be represented with black and white circles from the block Geometric Shapes:

The block Miscellaneous Symbols includes "Go markers" that were likely meant for mathematical research of Go:
