Great game. Not too hard, not too easy. I much prefer it over sudoku - more streamlined and less guessing. That said I love the pencil-in tool!

The game works as it should. But that is all it is. After 2 puzzles you are done with it. Nothing unique to add to the expierence

I am still addicted to this game and love the Android app. The only thing that is not perfect is that fat fingers sometimes change or add plays without me knowing or knowing where. I still love this game.

Challenging and addictive! Sometimes I get in my own way, then restart the puzzle and am able to start from scratch.

A strategic game, but not frustratingly impossible, it's entertaining, there's no ads. I consider this game both the perfect amount of challenging and relaxing.

fantastic app! simple to understand, and endlessly addicting! just wish the ability (and need) to highlight a row/column to see if there were possible duplicate rows was explained, but still great :D

An easy pick up put down puzzle that is nonetheless addictive. Follows the traditional noughts and crosses objective of preventing getting three in a line by means of logical deduction. And no annoying adverts, just to seal the deal!

a few puzzles seem like you have to guess, but maybe I am missing something

Great game and easy to use. My only complaint is that I need to pencil in two different colors/guesses at same time in order to use chain rule to solve some of the hard problems

Great game. 4 suggestions: change, or option, to make totals on left and top count down instead of up. 100% of the time, doing mental math to subtract those totals from 7,5,etc. They'll go negative if you mess up, but now they go above the total with no notification. 2: Option to include pencilmarks in the totals. 3: Option to place O with long tap vs. double tap. 4. For all games, same as others: dark mode would be big +++ & bring more play/$. Hope these suggestions can get on the queue...Thx!

Really love the range of difficulty levels in the weekly free games (obviously more free games, more often would be better :-) ). I would like to have a hint button where you could select the square you want filled. Enjoy the game play.

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.

The puzzles are literally IMPOSSIBLE to solve this is completely different from how I learned to play. There is no reason for numbers to perimeter the puzzle. In order to pick o you have to double - tap when there should be a multiple choice. I have yet to find a good app for this game and the best one so far is puzzle page .

Poorly designed. I love tic tac logic games, but this one isn't good. Way too many of the puzzles don't build outward when you fill in squares, so they just end up relying on guessing and checking whether it's correct. If the puzzles were designed well, you would never need to guess, even on the hardest levels. The app called "tic tac toe logic" has way better puzzles.

A nice little logic puzzle. No ads so far so it's already better then most of the free apps in the store

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?

Fantastic logic game; well designed UI. Tutorial is well written; should help those who think one has to guess to solve a puzzle. 3 stars because there were only enough free puzzles for about two days. To buy more, I think they should be about half the price. Should call this free trial. Offer ad version? 😬 Having numbers count downward could be more helpful for some. Given that everyone's brains with differently, perhaps an option in the settings to choose one or the other would be nice.
