About Lottery Toolbox

Lottery Toolbox is a small, independent project run by lottery enthusiasts. We have always been curious about how lotteries really work: why some jackpots are won every few weeks while others roll over for months, and how much the format of a game changes your chances. We could not find one place that answered those questions clearly for every major lottery, so we built it.

What we do

For 88 lotteries around the world we offer three free tools: a number generator that follows the exact format of each game, an odds calculator that shows the chance of every possible result, and a demo draw with a simulator that lets you see what years of play would really look like. Everything runs in your browser and is free to use.

Where the rules come from

The rules behind every calculation – how many numbers you pick, from which range, and how bonus numbers work – are taken from the official operators of each lottery and checked against current sources. Each lottery page shows the source and the date the rules were last checked. Lotteries change their formats from time to time, and when they do, we update the game and its odds.

The odds themselves are not copied from anywhere: they are calculated directly from the rules using standard probability maths, so they are exact.

What we are not

We are not a lottery operator, ticket seller or betting site, and we are not affiliated with any of the lotteries we cover. You cannot buy tickets or win prizes here, and the demo draw uses no real money. If you decide to play for real, always buy from the official operator in your country.

Our view on playing

We think lotteries are best enjoyed as cheap entertainment with a tiny chance of a big surprise, not as a plan for making money. That is exactly why we show the real odds so plainly. If playing ever stops being fun, please read our responsible gambling page.
