About this game

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.

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

Very challenging (in a good way) on Hard level. No ads!! There is a timer but doesn't matter as you can take as long as you want. Saves the puzzles (and timer) where you were so you can finish hours, days or months later. Good number of puzzles included for free. Well worth an occasional $1.99 for an additional 50 puzzles.

Its a great game and a fun puzzle and you can keep challenging youself to solve it even faster. I usually play this before I sleep to doze off. The only problem I think this game lacks is that, you could probably finish all the puzzles within a few weeks or a month or two and you would run out any new puzzles other than the weekly challenges. Hope the devs would keep adding more puzzles and other difficulties

Installed this after competing a Kurosu in the paper, same idea and fairly enjoyable however unlike the Kurosu whereby you essentially can't go very wrong if you're methodical the app seems to rely a lot more on trial and error which detracts from the overall enjoyment of it. Leaving many squares left open to interpretation and simply having to begin filling until you find a problem and having to back track just doesn't feel rewarding. Unless of course I'm actually missing something here?
