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.

ADHD focus aid

This game has served as an ideal aid for me to pay better attention to college lectures. It has no required auditory components and requires no reading, while providing a sufficiently challenging puzzle ti prevent my mind from wandering while not being so complicated I ignore the lecture I am listening to. It has no necessary time component, so the game can be paused and resumed at any time, allowing me to take notes as necessary or otherwise engage in class as needed.Both games in the series have been incredibly helpful, and are fun in their own right. I'm thankful to the devs for creating and maintaining these titles. Now working as a professional counselor, I recommend these games to my ADHD clients who are under-stimulated in lecture settings

I had a longer review written and when I switched screens it all got lost. So to recap: love the game, love the app, super simple and cute yet fun and challenging. Love that there are no ads and hope it stays that way. Love the optional $0.99 to support it and honestly I would pay more than that! Okay now to the good stuff. This is what I’d like to see in future versions:1) Continue game. When I close the app, my progress is forfeited and when I go back into it I need to start a new game. While not a dealbreaker, I’d like the option to continue the game I was playing before.2) Stats. While there is the leaderboard and Game Center stuff, I’m really only interested in playing against myself and seeing my progress. In the settings I’d like to see my stats like how many games I’ve played of each level and the corresponding best times and scores. 3) Tweaking the hints. While the hints are helpful, I have found a couple games where I think I’ve finished and the hints tell me a certain row or column is incorrect but I have yet to be able to figure out a way to find and then fix the error(s) and finish the game. The only option seemed to be to hit the back button until the beginning of the game and start over. (Maybe a start game over option would be good as well!) I’d probably like to be given the option to start over or highlight and erase the incorrect cells so I can finish the game. That’s all I have for now. Thank you!!

This game is so fun yet so simplistic. The storage optimization is phenomenal and gameplay-wise, this is really smooth!The gameplay is really fun with 5 different sizes of grids. The 3 given rules are easily memorizable and enough to solve the puzzle, and you feel very good when you solve a large grid.With not even 5 megabytes, basically anyone can get this game. The storage is very low and a good game for people with near full storage.This game is very visually appealing as well. The designs are simple, sleek and easy to see what’s going on. The color schemes go really well together and overall are very nice.I’d have to give this a solid 10/10. Simple yet nice colors, great storage optimization and solid gameplay. If your into puzzle games, I would strongly suggest this app. Great job, developers!

As others have said, this game does wonders for ADHD. Its also the only game that I consistently play for years when others I usually get bored of really quickly. Only thing that even remotely bothers me about it is that it likes to randomly ask permission to paste things when I go from one app to this one? Like, it randomly pops up the “Allow paste” thing for some reason
