In the Chrono Mine, it's all about competition to get a high score and climb to the top of your Leaderboard to get the best rewards, just like in the Frontier Mine.

You will be awarded with Clocks for the following actions:

• Upgrading any Mineshaft, Warehouse or Elevator will give you 1 Clock for every level
• Unlocking a new Mineshaft will give you 100 points according to the Mineshaft depth. (For example, unlocking Mineshaft 6 will award 600 points, and unlocking Mineshaft 12 will award 1200 points.)
• Additionally, if you finish the mine (All Mineshafts, Warehouse and Elevator are on the max level) with some extra Chrono Tickets or time left over, you will get 1 extra Clock for each second in the unused tickets and 1 extra Clock for every second left in your current ticket.

Once you have your total Clock score, you will see where you stand in your Leaderboard based on how other players are doing.
