Risk Odds Calculator

Add/subtract 1~4 highest/2nd-highest/lowest/all attacker/defender dice AND 1~2 bonus dice for attacker/defender. ALSO D4/D6/D8/D10/D12 options for house rules dice.

This app is very nice but not so helpful since you rarely need to calculate one single attack. Usually one needs to calculate a whole battle, i.e. multiple consecutive attacks, in which the amount (and type in 2210) of troops are changing after each attack. So I imagine a calculator in which one enters the amount of troops in the attacking army, the amount of troops in the defending army (and their type in 2210 - commanders, space stations and other modifiers) and it calculates the chances of winning the whole battle. If you can accomplish that I'm sure your app will be super popular with Risk players.

Looking good so far. Odds don't change, though, when you add more than 1 to a die (needed for a leader defending a stronghold in LotR Risk).

@outamoney - defender wins ties is the norm so there isn't an option for it. Attacker wins ties on certain rolls in Godstorm so they put an option in

An option for attcker wins ties but none for defender wins ties. What good is this for risk?

In Lord of the Rings Risk, the attacker dice are red and the defender dice are black. Your app has attacker dice black and defender dice white. This app has substandard value.
