## What is Zzing!?

Who is the One is the ultimate trivia challenge that puts your knowledge and speed to the test in a fun and competitive way. With three unique modes, there’s always a way to play and prove yourself!

In Play Event, you join a live quiz event with multiple players from around the world. The goal? Answer as many questions as you can, as quickly as you can, and climb to the top of the leaderboard. It’s not just about knowing the right answer — it’s about being the fastest to respond!

Want to compete with a friend? Play with Friends lets you invite someone to a one-on-one quiz showdown. You both play solo, answering the same set of questions, but only one will come out as the winner. It’s the perfect way to see who’s got the sharper mind!

If you prefer to practice on your own, Play Now is your go-to mode. This solo challenge helps you sharpen your skills, as you see how many questions you can answer without the pressure of competing against others. It’s a great way to prepare for the bigger events or just enjoy a quick mental workout.

Whether you’re competing with friends or players across the globe, Who is the One will keep you on your toes. Are you ready to prove that you're the quickest and the smartest?
