Hi RongQ, For Black Spirit's Adventure, you get 3 free dice daily. You click on the Dice Roll button on the lower right hand corner of the pop-up window, and can select which dice to use (normal white, colored special) just beside it. You can get more dice by landing on dice tiles and by completing 1 whole round of the boardgame. Whenever you get a dice it goes to your Black Spirit's Safe, locate the dice in the Safe and click on it to transfer to your bag, and from your bag you have to click it again to add to your reserved dice in the Black Spirit's Adventure pop-up window.
