Show HN: I built a free math-based puzzle game called Equatile

https://equatile.com
11•bbx•6mo ago
Hi,

I built Equatile, a logic-based puzzle game where you arrange number tiles on a grid to make every row and column equal their target values.

It's built using Expo and is available for free on iOS, Android, and the Web.

It's a game I've had in mind for almost 10 years now but never got to actually develop, until I came across Expo which made the process incredibly easy. I might open source the code on GitHub.

I hope you enjoy playing it!

love it!

I am really enjoying the game. It is really hard on my eyes for some reason. Other color options and increasing the size of the operators (+\-) seem like things that may help .
cristiduma•6mo ago
oh man, there goes 2 hours! I love it
gus_massa•6mo ago
In the web version, when I pass from a level to the next one, if's not super ultra mega obvious that the numbers changed and I got the new puzzle. I know it's a stupid feature requests, but I'd like an animation or something that shows that the number changed.

Nice idea, Expo looks neat too. You designed the website and apps with it?
