Lotto Number Generator

How random lottery numbers are generated

Numbers are generated using the Fisher–Yates shuffle (Knuth shuffle) applied to the full pool array, then the first pick numbers are taken. The shuffle uses Math.random()— cryptographically-random quality isn't needed for lottery quick-picks because all combinations are equally likely with a fair shuffle. Numbers are sorted ascending before display, matching official lottery ticket format.
