Then the game would be perfect -- Kalakey, 2024-10-14 ### ***** "Absolutely Obsessed" It is so simple, yet so effective. It’s a great puzzler to unwind as it is just difficult enough to challenge you but not impossible. Additionally the fact that you can determine your own level of difficulty of the puzzle every time is wonderful. 10/10 have shared with so many people. -- SilverCoLo, 2024-05-31 ### ***** "Fantastic" 0h n0 is easy to understand and fun to master. You can choose between a range of boards, the bigger the board, the more patterns to analyze and solve. Lower boards are great for new players to make sure they don't get overwhelmed and incrementally level-up. As they become a seasoned player they may know that each board can be completed without guessing, so the different sized boards can offer a zen like experience as they zip their way to completion. Every individual has a different baseline level of stimulation, allowing seasoned players to go back to the earlier boards and find their own zen board. My zen board is the 5x5. The competitive aspect is engaging for me personally. I compete with myself for the best times, but try to go for the endurance "boards completed" leaderboard for my zen board. I've been tracking a few active players in a spreadsheet and it's cool to see our rates vs absolute scores. The app itself is distraction free. No ads. No internet required. You can play anytime, anywhere, and fully immerse yourself into the game. The app does have some imperfections, right now there are 3 main bugs with the app, first is that you can't skip through the menu making the "impatient" achievement impossible, and the second is opening game center sometimes crashes the game. Pairing those two together can be annoying for competitive play. The other bug is that the timer gets disabled when you visit certain menus (How to play does this i think). I've also had some fun exploring potential shortcuts to save time. I've found out two major time savers which I call the blind dot rule and the related dot rule. I leave that as an exercise for the reader 😉 Overall, great game! ❤️ -- BareTuna, 2024-04-27 ### ***** "I love this game" This is still, after quite a few years, one of my favorite “go to” (uh, “g0 t0”?) games on the iPad. I know it hasn’t been updated in ages, and I’m fine with that, but one day I hope the developer can treat us to a new version with larger puzzles. 9x9s are too easy after a few thousand of them. :) -- kuma_no_pooh, 2024-03-26 ### ***** "App Store Hidden Gem" Quickly became my favorite puzzle game - and I’ve got a few! The replayability is glorious. Well done!! -- coldtakeout, 2023-12-20 ### ***** "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 -- Anon Ymos, 2023-11-30 ### ***** "Best of the best" This was one of the first games I tried on my phone. It never gets old, it is the definition of a great, engaging, entertaining, quick break. -- bsteck26, 2023-01-27 ### ***** "Great game" Similar to “oh hi” in that it requires some basic pattern recognition, and quick thinking. Better than “oh hi” because it’s a bit more complex and requires some math skills. Great way to wake up your brain when competing against the clock. -- Papa mison, 2022-09-05 ### *---- "Forcing to login" Horrible app, tries to force a Game Center login every time it opens. Terrible design -- chikbvfdyjkbxdr, 2022-05-06 ### ****- "Great game" Only criticism is that the hints are indecipherable. I'm comforted knowing no one else knows what they mean either. -- Doileybobber, 2018-02-16 [View all 0h n0 reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## 0h n0 In-App Purchases | Item | Price | |------|-------| | 0h n0 Supporter | $0.99 | ## Apps Similar to 0h n0 -
