Tic-tac-logic Light Vol 1
Each puzzle consists of a grid containing X's and O's in various places. The object is to place X or O in remaining squares so there are no more than two consecutive X's or O's in a row or a column, the number of X's is the same as the number of O's in each row and column, and all rows and columns are unique. There is only one unique solution for each puzzle. First click on a square places an X, second click places an O and third click brings the square back to its original state. Totally awesome fun awaits when you play Tic-tac-logic Light Vol 1!
