Generate random numbers instantly using ranges, dice rolls, and list selection for games, lotteries, or quick decisions.
High-Entropy Randomization Engine & Decision Helper
This generator helps you produce unbiased random values for games, lotteries, sampling, and quick decisions. Use Range for numbers, Dice for tabletop games, and List to shuffle names or pick winners fairly.
Uses crypto.getRandomValues() when available (cryptographically strong) and falls back to Math.random() otherwise. For lotteries/contests, verify rules; for cryptography, use a dedicated CSPRNG library.
