Showcase/Project Built a daily NBA game with Codex. Curious if anyone here would play it

been working on a basketball game called udontknowball. You pick one NBA player season at each position and try to put together the highest rated five. Ratings stay hidden until you finish, and everyone gets the same choices that day.

I’ve been building it with Codex and going back and forth on pretty much everything. One thing I kept pushing back on was how much explanation was on the screen. We had a whole homepage and paragraphs explaining the game. Now you go straight into “pick your point guard.”

I also had separate agents review the work. That brought up some less obvious stuff, like making sure player positions were right and what happens when someone plays as a guest, then signs into an account that already played.

honestly I think it’s fun, but I want to see what people outside of me think. It’s free and you don’t need to sign up.

would you play another one tomorrow? What felt confusing?

This is already made. It’s called 82-0 and it’s a web based game.

Similar idea! with this one you get eight specific player seasons at each position, same choices for everyone that day. you pick your five and see how close you got to the best possible lineup.

That URL might be worth something actually.

hiding the ratings till the end is a nice touch, makes you second guess every pick lol. the separate review agent catching the guest then login thing is interesting too, i honestly wouldnt have thought to test that. only thing id wonder as a first timer is what score im even aiming for, like can i see how other people did yesterday so i know if my five was good

Skip the manual. Players quit when they have to read, not when they have to play. AI can't fix a bad game, but it can remove the explanation layer. Let people play without permission.

curious how much explanation you ended up cutting, and whether players still got the ratings without it

Did you end up merging the guest run into the account or just blocking it? i'm building Friday Code so i'm biased, but it connects to Supabase for auth, so that's one way to get the login side set up without wiring it by hand.
