0h n0

It's 0h h1's companion game!
Category Price Seller Device
Games Free Q42 iPhone, iPad, iPod

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 four 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!

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.

Good with occasional annoying crashes
Moi et tu

Fun and doesn't get boring too fast. Addicting like Tetris.


Very addictive but one small criticism
kwallbmoc

I found this game over on Hacker News and love how it plays like a hybrid between Sudoku and Minesweeper. One small criticism is that the hints auto appear after a time delay. Can an option be made available to disable it?


A perfect little game

thank you


Not optimized for iPhone 6

UI is inflated / oversized


Meh

This game is okay. It keeps the 0h h1 mechanics, but that's it. This game is pretty confusing and frustrating. It doesn't have as much replayability as 0h h1.


Great!
The Raines

Great idea! Please make bigger sizes, 9x9 etc.


Hints not very helpful
punkassjim

"One specific dot is included in all solutions imaginable" is rather inscrutable. I still don't get how this is supposed to clarify anything.


Love it

Mastered it! Would love a followup with more depth. Check out dots vs 2dots to see a great example of how you could go with a sequel


Hints not helpful, dislike ios "games" app 'achievements'
Lachtaube

The hints are either difficult to understand or are not helpful. Would rather have a "red or blue here" hint than "maybe it could go in any possible space." Also, the 'Games Room' achievements that pop up (also in latest version of 0h h1) are annoying. There is no "clear board" option so I just backed out of boards to save time doing it by hand on the larger boards. Apparently there is an achievement for that! "Quitter!" Okay! You bet! Buh-bye! *delete*


Better than reviews would lead you to believe
Nicoliop

A lot of the reviews seem to be from people who find the game frustrating and the hints unhelpful, but that shouldn't influence you, dear citizen, from trying the game. The app itself has an excellent aesthetic and the puzzle has an interesting concept that is at least worth exploring. I enjoy it perhaps more than the original superstar 0h h1. Don't knock it until you try it!
