Random Number Generator
Generate random numbers with a cryptographically secure RNG or a seeded PRNG for reproducible runs. Draw uniform integers or decimals, normally or exponentially distributed values, or weighted choices, with uniqueness and sorting options, a histogram and sum/mean/median/min/max/std-dev stats. Roll dice with standard notation (3d6+2, 4d6kh3, d100) and see every die, flip coins with streak stats, and shuffle or pick winners from a pasted list — raffle mode removes winners from later draws. Copy results as text, JSON or CSV.
