This is an experiment of bad UX. Fun bad UX. But bad UX nonetheless.
You can see my creation at: https://ntoporcov.github.io/uno-phone/
I was inspired by the minds at https://reddit.com/r/badUIbattles to think what's the worst way to enter a phone number in a form. I hate UNO and I am apparently pretty close to being a masochist so I'd say one thing led to another.
I suppose so, but in the countless times I "played" it while developing, I wasn't able to win it.
