LuckEngine is a professional probability simulation and analysis tool designed for board game enthusiasts, tabletop RPG players, statistics students and anyone fascinated by the science of chance.
Simulate random events with a powerful dice engine supporting d4, d6, d8, d12 and d20 dice types. Roll up to 10 dice at once and visualize frequency distributions through heat maps and bar charts. Challenge a friend in Dice Duel mode with real-time win probability calculations. Use the Deck Shuffler to draw cards from a virtual deck while watching probabilities recalculate after every draw.
Run thousands of Monte Carlo simulations instantly to see the Law of Large Numbers in action. Design custom dice with your own values. Load quick presets for popular games including Dungeons and Dragons, Yahtzee, Risk, Monopoly, Backgammon and Craps.
Access a complete mathematical toolkit with over 10 probability calculators. Compute permutations and combinations, run Bernoulli trials, explore the Birthday Paradox, apply Bayes Theorem and work with hypergeometric distributions. Calculate risk-reward ratios, expected values and standard deviations. Use the interactive coin flip tracker with real-time statistics and consult the built-in formula reference guide.
Track your real-world experiments in the Entropy Ledger. Create named sessions for dice nights, card games and coin experiments. Log actual outcomes and compare them against theoretical probability with auto-generated visual analytics. Search, filter and export your data at any time.
Get AI-powered insights by photographing your game board for instant probability analysis. Chat with the Theory of Games assistant about Nash Equilibrium, the Monty Hall Problem, the Prisoners Dilemma and other classic concepts. Let the Pattern Hunter analyze your tracked sessions to find hidden trends and anomalies. Take probability quizzes and explore famous paradoxes.
Whether you are preparing for a D&D campaign, studying for a statistics exam, settling a debate about dice fairness or simply curious about how randomness works, LuckEngine gives you the tools to simulate, calculate, track and understand probability like never before.
