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 contains no ads and includes a Weekly Bonus section providing an extra free puzzle each week.

Peaceful and fun

This is a fantastic game and easily the most calming/meditative game from Conceptis. I don’t spend money on games in general but I buy puzzle packs for this game and other Conceptis games because I appreciate that these are high quality games and there’s no nonsense involved. These are some of the most interesting puzzles out there to solve, and there isn’t a constant stream of disruptive ads ruining the experience. If you love this game, throw them a couple dollars once in a while (you can restart packs and get a lot of plays out of them before they become too familiar).

I actually love the puzzles. My complaint has been the same since it came out, the color scheme is bland and a little depressing to stare at sometimes. I don’t see why it couldn’t have some color themes to brighten things up. After awhile of puzzles I have to stop because it feels like I’m doing office work. Conceptis said they see no reason to add them because apparently I’m the only one among thousands who has mentioned it. I’ve purchased a good handful of puzzle packs but I’ll never buy any others. Quite frankly if they think it doesn’t need color then you have to agree one or two puzzle packs is more than enough. You can reset and do puzzles over and over and you’ll do it differently every time. I can’t possibly memorize all the layouts so how can I be 100% certain that every puzzle layout is different?

Relaxing and addicting

I have loved this game since I first stumbled on it a few years ago. It comes with so many free patterns as well as weekly new ones that I don’t feel a need to buy more packs, I just clear out the free ones and do them again. I’ve never had an issue with glitching and there’s no ad pop ups which is so rare and nice nowadays
