Store description excerpt

Stack Life is a probability lab in your pocket. Build any random setup from dice, coins, and spinners — then see the exact distribution of outcomes, every probability precisely computed on your device, never simulated. Know the actual odds. Stack Life's engine calculates the full probability mass function for any combination: sum 4d6 and drop the lowest, roll 2d20 and keep the highest, count how many dice beat a threshold, or chain exploding dice. Mean, median, mode, standard deviation, and target queries update instantly as you build. The built-in solver flips the question: "what total do I need for at least a 25% chance?" Compare and explore. Overlay two or three setups side by side — is advantage worth more than a flat +3 bonus? The Compare tab answers instantly with an overlaid chart and a head-to-head stats table. Browse a built-in Library of named setups spanning RPG classics, board-game staples, and textbook probability problems, each drawn live by the same engine. Learn probability for real. The Learn tab walks through the concepts — independent events, expected value, variance, why advantage skews the curve, the law of large numbers — each illustrated with a live interactive distribution. Every lesson ends with a question; answer correctly and the next unlocks. Stack Life runs entirely on your device. No account, no network, no simulation — just exact arithmetic. Identical setups always yield identical results, making it the honest tool for anyone who wants to see the odds, not guess them.
