You will need Fire Cash to be able to unlock both the Impossible Island and the Key Forge.
Unlocking the mines will require key forging, found to the left of the Impossible Island. Keys can be forged for free over the course of days, with the option to use boosts to help reduce the wait times.
Be careful if you do use a boost to speed up the time to forge your keys - the power of boost will be used to forge the key and melt the boost (so you cannot use it again).
There are three types of Key you can unlock, and each takes a certain amount of time to forge:
- Bronze: 5 days
- Silver: 10 days
- Gold: 15 days
