App Description

Fill all squares so there are no more than two adjacent X's or O's in a row or column! 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 each column, and all rows and all columns are unique.

Tic-Tac-Logic is a single-player puzzle based on Tic-Tac-Toe, a pencil-and-paper game many of us used to enjoy as children. Using pure logic and requiring no math to solve, these addictive puzzles offer endless fun and intellectual entertainment to puzzle fans of all skills and ages.

The game features a ruler to help viewing and comparing rows or columns, counters to show how many X and O there are in each row and column, and pencilmarks to place temporary X or O when solving very hard puzzles.

To help see the puzzle progress, graphic previews in the puzzle list show the progress of all puzzles in a volume as they are being solved. A Gallery view option provides these previews in a larger format.

For more fun, Tic-Tac-Logic includes a Weekly Bonus section providing an extra free puzzle each week.
