🎲 How Random Number Generators Work

Computers use algorithms to generate sequences of numbers that lack any predictable pattern. This tool uses JavaScript's Math.random() function, which is cryptographically strong enough for most casual applications.

⚖️ Are RNGs Truly Random?

Technically, most computer-generated randomness is "Pseudo-Random." It starts with a "seed" value (often the current millisecond of the clock) and runs a complex math equation.

For lotteries, games, and giveaways, this level of randomness is considered fair because predicting the next number without knowing the internal state is practically impossible.

🏆 Common Uses for RNG

  • Lottery Picks: Choosing unconnected numbers for tickets.
  • Contests: Picking a random winner from a list of entry numbers.
  • Games: Rolling virtual dice or creating loot drops.
  • Decision Making: Flipping a coin or breaking a tie.
