Roll four dice using the 4 d6 dice roller.
To roll all four dice at once, you just need to click on the 'Spin all' button. All 4 of the six-sided dice are then rolled at the same time. Alternatively, should you wish to roll each of the 4 dice by themselves, just click them individually.
Yes, you can see the results appear after each roll (or spin). To get the history of your rolls, check the "Results" tab. Here you will see the list of previous 4d6 dice rolls that have made in this session.
