Emerald City Bazaar is a new way to earn Emerald points for the Leaderboard. This is a recurring event that will run concurrently with Bazaars (Previously called Bonanzas).
Collect items when you beat new levels and trade them in. The goal will change, so keep an eye out.
For example, the “Magic Beam Bazaar” will run for 2 days. Trade all the Magic Beams you’ve collected before the timer runs out.
