Use Game Helper to help generate dice rolls of any number of dice of any number of sides while optionally adding a modifier to the roll. Game Helper also can help simulate board game battle results (similar to "Risk"). It can simulate battles of any number of attackers versus any number of defenders. It can also calculate the probability of winning a battle of 2 tp 12 attackers versus 1 to 11 attackers.
This skill does not require any special accounts or hardware.
