Rules Each puzzle has to be solved according to the following rules: 1. Each cell should contain either X or O. 2. More than two equal X or O immediately next to or below each are not allowed. 3. Each row and each column should contain an equal number of Xs and Os. 4. Each row is unique and each column is unique.
