ArkhamCalcRedux is a small utility that is designed to be used in conjunction with Arkham Horror, a 2005 board game published by Fantasy Flight Games. Many of the encounters in Arkham Horror involve rolling a number of dice and counting each success, which in most cases require rolling a five or six. Given the number of dice that you are allowed to roll and the number of "successes" required to pass the encounter, ArkhamCalcRedux calculates the probability of succeeding in the encounter. ArkhamCalcRedux can also take game conditions into account, such as being "blessed" or "cursed", which affect the probabilities of success beyond the standard calculation.

ArkhamCalcRedux is also compatible with Eldritch Horror, the brand new board game released by Fantasy Flight Games!

Intended to replace the original.
