Mathstick 2 is now ready!

Same as my first version, you can earn sticks to unlock the next level and the challenges get harder as you progress. With the newly added Puzzled Maker, you can now create your own matchstick puzzles and generate a shareable link to stump your friends :)

For example, check out this custom challenge I just created: https://mathstick.github.io/play?q=ktoylsjcnmylbetuinmylielj...

Feel free to share your puzzles below and feedback is welcome.

The answer to all of these should be moving a stick over the equality sign to change it to an inequality sign.

This is too tricky to be allowed. Let's play a fair game :D

I think I broke it a little, playing around with INT64_MAX - https://mathstick.github.io/play?q=hrojihaacciabcmtskiistbij...

Edit: mostly directed at OP, the puzzle maker claimed something like 12 identical solutions for the same puzzle

Yeah, you did! It's integer overflow, good catch!

Nice one. I spent about 15 minutes playing, thank you.

Glad you enjoy it!

Highly recommend y'all try playing with the Puzzle Maker first! It’s a great way to get a feel for the shape of numbers and the different moves you can make.

I personally found this 'learn-by-doing' approach really helps me understand the patterns before I tackle the harder levels.

Nice! What did you build this with?

Also, submit it to https://hnarcade.com :)

js+css, angular only for fancy pop menu and dropdown list, no angular material though, as as to keep it simple and lightweight.

sure, will have a look. thanks!

Would you be willing to add a manifest so this can be "installed" as an app on Android?

by trangram 5 hours ago

sure i'll consider converting it to PWA if people prefer playing the main game than creating and sharing puzzles with the Puzzle Maker.

by ncruces 4 hours ago

I think you can just pretend to be a PWA, no need for code changes.

You may need an unused service worker, or not, I don't remember.

This just means your site looks like an Android app (but still needs net, etc).

Thanks, I used to do something like that when I made a tabletop like card maker using three.js + angular 8, but it has been a long time ago, I need to catch up with the details how to implement it with angular v21 since it is almost a completely new framework compared to the old versions
