Unlock a Board
If you want to play a board that you haven't unlocked yet, press "Ctrl + Enter" or "Alt + Enter" on the board selection screen and choose the board.
Hidden Quest
Begin as you normally would with the Silver Quest. Once you have completed the Silver Quest, finish the Gold Quest. After both quests are completed, there is a bonus "Hidden Quest."
Board View
If you want to look at your board without the time ticking, pause the game. Once the game is paused, press the control key and move the menu to the side. The majority of the board (approximate 75 percent) will now be in view.
