These electronic dice can be used to play games even in the dark, so you don't have to worry about power cuts or being bored in darker environments. When the battery-power runs out,you need to put the dice into the charging compartment and then charge the case with a Type-c cable to charge the dice. We've included a charging illustration card which shows you the correct placement of the dice. It may take some time to place them the first time, but after a few more plays you will be able to place them quickly and correctly.
For any other questions, feel free to ask us and we will answer them promptly.
