I built Name100Challenge after seeing how deceptively difficult this challenge can be.
The game runs entirely in the browser and requires no sign-up. The timer starts with the first valid answer, duplicate names do not count, and players can practice by category before attempting the full challenge.
I also added a daily challenge, a leaderboard, mobile-friendly input, and a men's version.
I would especially appreciate feedback on name validation and the 12-minute game flow. If you find a real, notable person or common alias that should be accepted but is not, please let me know.
