This trick will allow you to roll whatever number you wish to. First, press the Control (Ctrl) key and the "D" key simultaneously. Hold them down. Then, still with the keys held, use the mouse to click between the two dice you can roll. Now move the mouse left to set one die to the desired number, up to set the other, then release the mouse button and you'll roll the dice at the set number, which can be any one you desire.
