• Your Boosts and Instant Cash Items are not available in Frontier Mines, therefore there won't be any Boost Inventory icon there.

  • From the Frontier Mines Rewards and Shop you can obtain different items to help you progress: Frontier Multipliers, Time Jumps and Frontier Credits.

  • Frontier Multipliers and Time Jumps will be applied as soon as you receive them, while Frontier Credits remain until the end of the event, and you can see the current amount in the top-right corner of the screen.
