Every lottery ticket
has a single number.
Global Lotto Index turns any valid combination into one deterministic index — and back. Play classic, play by index, backtest decades of draws, and watch the math do its thing.
Index Mode
Type a single number, get a unique ticket. Reversible, deterministic, and provably uniform across the combination space.
Deep analytics
Frequencies, gaps, hot/cold trends, odd/even splits, sum distributions and entropy — for numbers and for indexes.
Multi-country
