The Chest Collector is a milestone found at 100KM between 9th and 10th miner. It look like a pile of boxes and you just click on it to acquire the structure. It works both during online and offline progress. A certain % of the chests that spawn on your mine will be collected and stored, up to a limit. These chests are not subject to timers, i.e. won't disappear until you collect them.
You can upgrade the storage and chance of Chest Collector from Craft Center up to level 10.
You can collect chests from Collector by Shortcuts shift+click.
- Historical notes
- This feature was added to Mr. Mine released at 4th June 2021
- Initially the chest collector didn't store the type of chest collected, only the number of chests in it and it rolls the type when you collect them. So there was a chance your gold chest could be deleted, but also a chance all your basic chest rolls get a second chance to be a golden chest.
- As for the update of 17/12/21 the chest collector now stores both types of chest, basic and gold.
