Deadlands Classic Calculator

Monte Carlo probability simulator for trait rolls with acing dice and bust detection.

How Deadlands Classic Rolls Work

  • Roll N dice of your trait's die type (set by Aptitude level).
  • Acing: A die showing its max value explodes — reroll and add (chains indefinitely).
  • Keep only the single highest result from all dice.
  • Success: Result ≥ Target Number (TN). Each 5 over TN = 1 Raise.
  • Bust: More than half the dice show 1s before acing — critical failure.
