Stellar Keno

alexgandy

Hello, I'm looking for beta users of my new app, Stellar Keno (https://stellar-keno.herokuapp.com/).

I needed a project where I could learn about the Stellar API, while learning NodeJs and React. I figured an app similar to stellar dice would be a great tutorial.

It would be great if you all could take a look at the sign-up flow and gameplay, and let me know what you think.

Cheers,
Alex

Don't work.
The sign-up ok, but impossible to login after registration.

jpchabry Sorry, I don't follow? Were you not able to login?

I like the visual.

First deposit I didn't include the memo (I hate this system - the fact that it's as ubiquitous as it is just goes to show how early we are in this whole sort of thing), so that was a drag. Probably having much more explicit design to ensure people actually read and understand would be good. Also, balance definitely did not show up in under 30 seconds. Still waiting for it to show up.

dlohnes

Yup, still never showed up. Any chance you want to send me my 0.02 XLM back since I was brave enough to test your system @alexgandy ? GAONEFUU2PUADRHVVXRSSXEQJW7XXOOEWZSQEY2WR4PUBWGUDSR7VFEU

dlohnes Thanks for trying it out and sorry for the hassle. I just returned the 0.02 lumens. I'll definitely add a confirmation button or something to the deposit step.

Edit: I figured out the issue. Your deposits were found, but some strange floating pointer math was happening with the balance addition.

Thanks for resolving it for me, and glad I could help unearth a bug ?

For what it's worth, the developer docs from Stellar recommend using a BigNumber library in order to avoid issues with floating point math. https://www.stellar.org/developers/guides/concepts/assets.html

Also, in the future it'd be nice to have any project like this support the testnet so that people don't need to worry about losing their XLM. That's what it's for so we may as well use it ?

alexgandy

dlohnes Yep. That's exactly what I did...I already had it in place for other operations, just stupidly not that simple addition.

I was thinking about deploying a testnet version of the app as well. Thanks for the suggestion/reminder.
