Star points (J. hoshi, lit. "star") are the nine points on a 19x19 go board marked by small dots, where handicap stones are placed. They also serve as a visual reference for the players. Otherwise, they have no effect on the game. They are one of the named points on the board.
The Japanese term hoshi can also refer to a win (shiroboshi, "white star") or loss (kuroboshi, "black star"), or the circular white or black mark used in tournament grids to show such a win or loss.
The Korean term "hwa jeom" or "flower point" originates from traditional Korean boards in which the star points were indicated by flowers.
A 13x13 board has only five star points.
A 9x9 board also has only five star points. However, some leave out that in the center, some those in the corners.
