Hi Moecki, Finally! Thanks a lot for sharing all these highly valuable input and also taking part. Your insights are genuinely helpful. Let me walk you through my thought process on the areas you mentioned..

1. "up" and "down" buttons - Great point! During the design phase, I took inspiration from vertical number rollers used in physical ticket machines. That's how it was done.

2. Random selection: I intentionally designed the number picker to encourage users to choose their lucky numbers for that day, rather than having the system generate them. But I get it “Random Pick” button would be a helpful option. I will give it a try in coming days.

3. user name: Ah yes! that’s been a bit tricky! 😅 Even I occasionally hesitate whether to include the @. Technically, the system is set to accept both formats, so it will work whether or not you type @username.

4. The "Top buy" section should not have such pale design. I checked the UI on several devices, but didn’t notice contrast issues still, screen settings can vary, and I will further look into it.

5. Steem game - Yes, for the Steemit users. Also having our own website was crucial for the app functionality.

Again, thank you for taking the time to share your thoughts, it helps me make the experience better for everyone. Wishing you all the best in this round! 🤩
