App description: 0h h1 is a little logic game that follows three simple rules:

- Three red tiles or three blue tiles next to each other in a row or column isn't allowed
- A full row or column must have as many blue tiles as it has red ones.
- No two rows are the same. No two columns either.

Simply tap a tile to make it red or blue and complete the grid.
0h h1 gives you unlimited puzzles for all four grid sizes:

4 x 4
6 x 6
8 x 8
10 x 10

0h h1 is free, without ads, without social network requirements, without locked features and without nag screens. 0h h1 is a little gift to you. We hope you enjoy it.

0h h1 can also be played on 0hh1.com.

mrtnkl's comments:

My new game is out. It's called 0h h1. It's free, it has no ads and no IAP. It's a little logic game and it's a little gift. I'd love to hear what you think of it.


It's also available on the web:

Thanks. Very clean interface and surprisingly challenging.

TA Forum pro tip: put the iTunes URL inside appinfo tags in your first post and it'll link the thread to your app (click quote on the first post of another thread if you're not sure how).

Really nice game, although it would be nice to be able to up the difficulty level and to restart the puzzles without doing it one move at the time. Also add gc-achievements!

It would also be cool to do bigger puzzles!

Anyway, nice and clean and plays great. I expect lots of copycats though.

Q4/ have released a "companion app" called 0h n0. It's another nice, clean puzzler which is free with no ads or IAPs.

I'd create a thread, but the TA app can't find it in Search and it's too much of a pain in the neck to create a thread from scratch in the app as it doesn't support short iTunes links. /rant

Anyway, here's the link:
