Gold mine special requirement?

[Mophne]

I know that trophy unlocks in Mystery mode when you come across a modifier that turns all your blocks golden.

However this never happened for me so far.

Do I have to survive a long time or pick a high "difficulty" (speed)?

Or am I just really unlucky?

For the last 2 weeks I playes 1 hour of mystery every day because it annoyed me that the trophy won't happen, making a whopping 7 hours of this game mode without the gold modifier.

And more hours I haven't counted before that.

 

Pls help?

It's definitely luck based. Just keep playing and you'll eventually get it. I didn't up the difficulty or anything.
