    Hey, maker here. After launching a daily word search game, I randomly thought of this math game while driving. Finally got around to making it and I think it turned out pretty cool. It’s a math search game that’s meant to help you practice your quick addition, subtraction, multiplication, and division skills. I’m hoping it’ll help people (even those like me who aren’t big on math) learn and increase their speeds. (There are also some settings you can enable to make the game harder) If you try it out, please let me know if you found it fun, if you have anything you’d like me to add, or if you…

    Recently moved to Egypt, and in dire need to get the numbers down. Great excuse to explore learning software some more. Possibly very niche, but maybe it is useful for someone else out there. Feedback is always welcome.

    Hello HN, last week, I stumbled over an old project of mine called Click The Number. I built it about six years ago to compare my clicking and reaction speed with that of my friends. The idea is simple – just click on the numbers in orders as fast as possible. I couldn't resist and rebuilt a lot of parts again, making them a bit nicer. I updated the design and added some features like a personal high score. It lets you keep track of your own best time (which makes it ever so _slightly_ more addictive). I'm curious what you think about it, and if you have any ideas where I could take it. Have…

    I have always dreamed of learning Swift and creating apps for iOS, but I never found the motivation to do so. I was scared by the complexity and the learning curve of programming with UIKit and Storyboard. I thought they were too complicated and too boring for me. But then I discovered SwiftUI, the new framework for building user interfaces for Apple platforms. I was captivated by its simplicity and elegance. I watched some videos and read some articles about it and I was blown away by what it could do. I decided to give it a shot and see if I could learn it and make something with it. I set…

    It's like a mix between Picross (Nonograms) and Polyominoes. It's a minimalist puzzler which has no text, no tutorials (none required) and no ads set in a relaxing environment. App Store: https://itunes.apple.com/gb/app/shapeuku-shape-puzzle-game/i... Play Store: https://play.google.com/store/apps/details?id=com.dtbgames.s... I have a bulk load of Android promo codes to give away, so if you'd like one let me know! (Sorry iOS users, I have no free codes left!)

    Well HN, I've finally produced something I think is worthy of sharing, but I didn't do it "in a weekend". Yeah, it's an iOS puzzle game. And yeah, it's a game I built because I wanted to play it rather than based on market research, so all this sort of makes it the antithesis of a popular HN post. But whatever. Still hoping for some of that patented (har har) expert HN feedback. Critique any part of it except the music. Also, PM me for upgrade codes, or I can post some here if there's any interest. Download (it's free):…
