About 0h n0

It's 0h h1's companion game!

Remember that little logic game called 0h h1? Well, we've made a challenging new puzzle game to go along with it! Meet its companion... 0h n0.

0h n0 is a lovely little logic game that follows its own three rules:

- Blue dots can see others in their own row and column.
- Their numbers tell how many.
- Red dots block their view.

It's up to you to complete the grid without ever having to guess. Simply tap a tile to make it blue or red and complete the grid. 0h n0 gives you unlimited puzzles for all grid sizes:

5 x 5
6 x 6
7 x 7
8 x 8

And now included: 4 x 4 and 9 x 9 boards! Yay :D

Each puzzle can be played in perfect Zen mode without any pressure. But you can attempt to beat your personal best time in the game's time trials, unlock fun achievements and compete with friends in leaderboards.

0h n0 is free, without ads, without social network requirements, without locked features and without nag screens. 0h n0 is a little gift to you. We hope you enjoy it.

0h n0 can also be played on 0hn0.com.
And if you haven't played its sibling yet, go visit 0hh1.com.

I've decided to come back after a few months and re-review. Is it worth a dollar? Eh, I don't really think so. Once you get comfortable with 7+, anything smaller is incredibly boring. So you eventually lose half the game. I've also played enough (not a ton) to realize boards are being recycled. Since my last review, I haven't seen an update either. Essentially, it was fun while it lasted, but it's pretty dull after a while. My score is 4,000

R70%
by R####:

I play it all the time, people always want to know what game I'm playing. I used to think everyone on the leader boards cheated until I got number one on one of the lists.

It doesn't remember my settings of hiding the hint button and showing the timer. Other than that, it's excellent! Is gladly give a perfect rating if it remembered to turn in the timer and turn off the hint button.

Y70%
by Y####:

I just hit 150k points. This game is perfect for when you wanna lose some time. Loving the option to enable/disable the timer so you can track more than just points. Definitely better than 0h h1 imo

H70%
by H####:

This is my favorite way to waste a few minutes. Easy to pick up, but somehow it never gets boring.

Y70%
by Y####:

A very good game. Lately the game restarts before I am able to complete a level. Would be five stars if it were playable

F70%
by F####:

It's like a Sudoku, but since there's a timer, I gotta beat that hi-score I did.

Z70%
by Z####:

The game would greatly benefit from larger levels - 9x9 is quite simple. Something like 12x12 would be cool (at least on tablets - there may not be enough on-screen room for 12x12 on phones).

Better explanation on how to play. Uninstalling it.

Nice simple game for people who lean to this type of game. One of my favourites.

I love this game, but when I recently switched to Google Fi and the Nexus 5X I started having this issue. Fi uses both T-Mobile and Sprint, and switches between them when the current one loses signal. During this switch, if the game is opened it will crash and the phone goes back to the home screen. This also happens with 0h n0.

So, about last week I accidentally purchased the game while checking the options(I mistakenly pressed 'buy' instead of cancel) and I did file a report to Google about it. Few days later, it did show that I haven't bought the game in the options(although no refund to my phone credit card XD), but now whenever I exit the game, I found out later that my progress keeps getting rolled back to nothing and I always start with the SAME puzzle. Are you guys doing this on purpose just because I did that?

The game is stuck in Loading screen when I try to play. Tried several times and waited 5 min. I could play the tutorial with no problem tho... !! Using Samsung S3

Interesting game of dots, not too addicting but challenging.

Last updated broke the game and I can't complete any 9x9 games. Will leave 5 stars because the devs are great and keep up with regular updates. Will change review when fixed.

L70%

Excellent game. A simple, well designed puzzler. No annoying ads, no pay to win; one of the more conscientiously-made games in the app store. I originally had two questions about this game: whether each puzzle can be solved through pure logic (no guessing) and whether each puzzle has a unique solution. The answer to both, I've become confident, is "yes". This puts it on the playing field with Sudoku (though Sudoku can be more difficult). It was worth a dollar to me and it will be to you too.

Elegantly simple interface, logic puzzles tricky enough to keep you thinking. Hint system neither gives away the answer outright nor tries to extort microtransactions for using it; rather, it teaches you to play the game better.

perfect mechanics, perfect aesthetics, perfect execution, just perfect

U70%
by U####:

It's easy to play, yet still challenging. Beautiful, responsive, no ads, just amazing. Love everything about it, and I would highly recommend it.

H70%
by H####:

Or like Logic dots. I especially like 0h, n0 seems to have logical solutions - no guessing is necessary.

U70%
by U####:

As much as I enjoyed the game I was removed from the leaderboards for no reason. Now this game is dead to me..

I love oh h1 but this one's good too. Again very comfortable interface. Great game

U70%
by U####:

It's nice and all but it glitch all the time and that's very annoying. Sometimes screen got white and black when you tap the circles. You should fix it.

U70%
by U####:

A fun, well-designed game with no extraneous elements or annoying ads. It is just right. Lovely!

C70%
by C####:

I'm just gonna copy and paste my comments for 0h h1 here because that's how well they complement each other: It's simple with just enough challenge to keep you going. It's smooth to run and lovely to look at. A well executed puzzler.

But why can't I move it to my SD card?

V70%

Good clean logic game, no clutter no ads, polite donation possibility. I really like it.

One request: don't fade away the results board until the user taps the screen. It would be nice to be able to study it a little longer.

U70%
by U####:

Great companion game to 0h h1, but the hint engine is not up to par with 0h h1. (See that blue dot that was there at the beginning? Well, it's part of the solution.)

now only works with data on....it sucks

But how's it possible that "810 dots" achievement has a reward of 4000 XP only??

Google Play Games service connection is bugged.

Game is hard

Very challenging, particularly at the larger boards.
