Lottery Odds Calculator

How to use it

1. Choose a Game: a preset with its prize tiers, or Custom game to set your own pools.
2. For a custom game, type the Numbers in the main pool and Main numbers on a ticket, and the bonus pool and bonus numbers if the game has them.
3. Read Top prize odds and Chance of any listed prize. The table lists each tier with its tickets and chance.
4. Use the figures to compare games. Every draw has the same chance, whichever numbers you pick.

How the chances are calculated

A draw takes d main numbers from a pool of n, and j bonus numbers from a pool of m; every draw is equally likely. A ticket with k main numbers and j bonus numbers matches exactly i main and b bonus numbers in C(k, i) × C(n − k, d − i) × C(j, b) × C(m − j, j − b) of the C(n, d) × C(m, j) possible draws. For most games d is k, the numbers on a ticket; On Numara draws 22 numbers for a 10-number ticket.

Chance(i, b) = C(k, i) × C(n − k, d − i) × C(j, b) × C(m − j, j − b) ÷ (C(n, d) × C(m, j))

• The counts are exact whole numbers, so nothing is simulated and nothing is rounded before the division.
• A joker is one of the n − d numbers the main draw leaves, so it multiplies every draw by n − d. In Sayısal Loto it splits only the 5-number tiers: 5+1 needs the joker to equal the ticket's sixth number, which the draw did not take.
• The EuroMillions tiers follow the prize table of euro-millions.com, a site that says it is not endorsed by the operators. Its format matches the UK National Lottery's game page. Powerball follows its Wikipedia article.
• Eurojackpot and LOTTO 6aus49 follow the class tables of lotto.de, which list the odds of each class. Loto (France) follows the rules of La Française des Jeux, and Mega-Sena the prize page of Caixa Econômica Federal.
• The four Turkish games follow the rules pages of Milli Piyango, which list their prize categories. Those pages give no effective date; the rules were read on 10 November 2026.
• The generic 6 of 49 game has no official tiers, so the table lists every combination with at least one match.

The rules of the Turkish games

• Sayısal Loto: 6 numbers from 1 to 90, and a joker from the 84 numbers left. Prize categories: 6; 5 and the joker (5+1); 5; 4; 3; and 2 numbers.

The rules of the other games

• Eurojackpot: 5 numbers from 1 to 50 and 2 Euro numbers from 1 to 12. Twelve prize classes, from 5 and 2 down to 2 and 1 (lotto.de).
• LOTTO 6aus49: 6 numbers from 1 to 49 and a Superzahl from 0 to 9. Nine prize classes; class 2 is 6 numbers with the Superzahl not matched (lotto.de).
• Loto (France): 5 numbers from 1 to 49 and a numéro chance from 1 to 10. Ranks 1 to 9 pay a prize, and rank 9 is one number with the chance, or the chance alone. The rank for alphanumeric codes is not included (FDJ rules, article 8).
• Mega-Sena (Brazil): 6 numbers from 1 to 60, with prizes for 6, 5 and 4 numbers matched (Caixa).

What the odds do not say

• Prize amounts, jackpot sizes and rollovers. The page does not model money, so it cannot give the expected return of a ticket.
• The price of a ticket, tax, or how many tickets you buy.
• Optional extras such as the Süper Star of Sayısal Loto, which has its own prize categories and is not included.
• Any strategy. Choosing numbers that few others pick changes how a prize is shared, not the chance of winning it.
