The Treasure Cave was a special area that was only accessible once a day, reopening at 12 AM UTC and gave players free rewards. As of August 2019, the Treasure Cave has been removed.
In each of its rooms, you'll be able to choose among 4 doors. Each contains either an awesome prize which will be stored in your Treasure Box or a trap which will make you lose it all!
At any point, you can choose to leave the Cave and claim all the rewards in your Box, or keep on exploring for better treasures... but if you find a trap your loot will be lost! However, you may also pay gems to keep your rewards and continue exploring. The gems cost increases each time you hit a trap.
To help you on the way, every 5 doors you'll find a risk-free Bonus Room. No chance of finding a trap there, and they have even bigger rewards!
If you're up to the challenge, in rooms 30, 60, and 90 there are INSANE rewards guaranteed. These big treasures change every day, so make sure to come back!
