Just before the 4 minute mark in the video below, the player receives 157,682 gold after using gems to purchase all 3 Ice Wizards in the shop. Does anyone know what causes you to get the "bonus gold" as the developer called it? The devs plan to patch this tomorrow morning so any timely information would be appreciated!
