Noughts And Crosses (aka Kurosu) is a puzzle based on Tic-Tac-Toe, but where the aim is to fill the grid with 0s and Xs, ensuring that there are never more than two of the same symbol consecutively in any row or column. There must also be an equal number of each symbol in every row or column. For this reason, the grid always has even-numbered dimensions.


The puzzle may also appear as Binairo (aka Binary), in which 0 and 1 are used, rather than 0 and X.
