Online Scavenger Hunt Website

Hey there, I have some suggestions. Hope my feedback doesn't come across as discouraging!

First impression: sorry to say, it makes me skeptical. "Is this a scam? Why is someone giving away money?" Not saying it's a scam, just that it needs a re-write to avoid scaring people off.

I'd separate the site headline into words.

You can use a fun script font like this but it's best not to use it for everything.

I would drop "scattered and buried" from the site title. I would drop "for anyone to join" from the tagline.

Suggestions:
"Step 1: Choose an event to join"

"Step 2: Find hidden clues on the Web"

"Step 3: Unlock further clues as you progress"

"Step 4: Be the first to find them all, and collect your reward!"

The main part of the page being a single image will give people trouble who try to read it on their phones. And it's safe to expect between 1/3 and 4/5 of visitors will first see your page on mobile, depending on where they're coming from.

Hope that helps!
