- 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.

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.

A simply great time.
This game is very interesting, fun, and designed so simplistically and yet is so visually appealing. Aside from a few issues it's one of the best puzzle apps I've ever played.
One issue is it doesn't always save my in progress sessions if I even put the app running in the background and only sometimes retains it. And never keeps it if I outright close the app.
The second issue is sometimes to figure out the next move, you need to compare a completed line with one that has two blank spots, but on the higher difficulties it can be an eye strain to maintain that observational stare. I suggest being able to press a button that lets you dim everything but two rows/columns and select the ones you want to focus on/light up. That's just one possibility, but any way of making it easier on my eyes would be greatly appreciated.
I also wanted to thank the devs for not putting ads in this, even though it's free. I will absolutely put some money down for this later when I am able to.
And on one final note. I wanted to say that making the hints free is really great. I struggled to understand the finer details and nuances of the game at first but after using the hints enough I quickly figured out many of the things I was doing wrong and became a much better player for it. So I am also deeply appreciative for there being no micro-transactions and thus no pressure put on me to buy them for the hints.
My favorite puzzle game
I have never made a review for a game but this game is honestly so great. There are no ads first off , which is amazing. Everything is free. I love the concept and how simple yet difficult the game is . I reallly wish there were more levels though because the hardest level is now too easy for me due to how much i play . But all in all my favorite game ever!
I was introduced to this game by a friend - she kept playing and I wanted to see what it was all about. I quickly became addicted.
