Cooking Fever Update Version 16.1.0 has several updates.
New Casino- Watch ads about 4 hours to receive a Mystery box.
Spend 1620000 Coins to receive a Mystery box.

I think this update is neither good nor bad.
It's just adding two new currencies.
I don't play casino with coins for a long time,
besides completing daily quests and making videos.
I still like play in the restaurant.
