Double Dragon Chests

Double Dragon Chests is a Treasure Hunter promotion and may not currently be active.

Double Dragon Chests is a Treasure Hunter promotion that originally ran from 8 March 2018 to 12 March 2018. The dragon chests replace standard chests randomly with each dragon chest granting a prize multiplier. Similar to the Dragon Chests promotion, adamant chests will grant 2× the amount of prizes, rune chests will grant 3× the amount of prizes, dragon chests will grant 4× the amount of prizes, and god chests will grant 5× the amount of prizes. There is also a chance for double dragon chests that are unique to this promotion, where they grant double the amount of normal dragon chests. Furthermore, an ice chest may be offered, always containing 1–10 ice cube tokens as the first choice.

After opening a chest, players are offered three prizes of same rarity to pick from.

Trivia

• The promotion on 29 March 2021 began at the game update on that day unlike at the start of the day as usual. This was likely due to the game not having received updates recently.
