The Victory Box is a special box that opens every 22 hours. When ready to be unlocked, the cards contain gold and gemstone rewards. The chest can be opened at any time and can be upgraded after earning a certain amount of medals during matches. The chest is upgraded from silver to gold, then gold to artifact after more medals are earned. The color of the chest may not always change from one upgrade to the next, sometimes adding size or an effect to the chest can be a visual indicator of the upgrade. Medals are earned from matches to destroy bunkers and bases and do not require a victory to be won.
The Victory Box consists of 7 linearly progressive stages. Each upgrade increases the contents of the chest. The following table summarizes the appearance and content of each stage:
Level | Size | Number of Cards | Gold | Diamond | Required Medal |
1 | Small | 25 | 100 | 2 | 0 |
2 | Medium | 47 | 150 | 2 | 5 |
3 | Medium | 64 | 200 | 5 | 7 |
4 | Medium | 76 | 250 | 15 | 11 |
