During this promotion, players gain charges for every chest they open, filling the wonderbar meter. Once the player has reached the prize category they want, they can activate the wonderbar and their next prize will be from that category or rarer. Additionally, there is a purple gem that gains charges as chests are opened. Once the purple gem reaches 100% charge, the player can activate it to guarantee a prize of ultra rare rarity. The wonderbar meter and purple gem are both filled and activated separately. Sometimes, extra charges are gained for opening chests or some charges are saved when activating the wonderbar and purple gem.
The use of Hearts of Ice is permitted during this promotion.
Promotional prizes include the previously discontinued lucky items shown below.
