Lotto: how do the numbers and prize categories work?
Italian Lotto draws five numbers from 90 on each wheel. The displayed 1 in 43,949,268 describes a specified set of five on one wheel. It is not the probability of an estratto, ambo or terno. Choose the wheel and prize category before comparing; past delays do not change the next draw.
Every main number is included. Bonus numbers remain separate and are never mixed in.

Binomial reference with Bonferroni correction across all displayed numbers. Under uniform, independent draws, coverage is at least 95% for one sample fixed in advance. Searching across different sample windows is exploratory; an outside point does not establish a biased draw.
Main numbers only; bonus numbers are excluded. Historical differences do not change the probability of the next draw.
Frequencies and historical absence describe only the selected sample; they do not change the probability of the next draw.
C(n, k) counts unordered selections without replacement. Independent pools multiply; the probability of one complete outcome is the reciprocal of this total.
Analyse a Lotto · Five-number draw combination list
Example: a list with three rows, including one repeated complete combination, covers two distinct outcomes out of 43,949,268. Its exact-match probability in one fair draw is 2 / 43,949,268, not 3 / 43,949,268. Include every number pool in the modelled outcome.
Repeating an identical complete combination does not add another distinct outcome. Sharing some main numbers is different: combinations with different bonus numbers can still be distinct. Overlap describes the list; it does not identify better numbers or calculate the chance of any prize.
Compare 2–200 combinations you enter, inspect duplicates and overlap, model costs, and export a CSV or printable report. If you model a purchase, costs include all entered rows, including duplicates. The analysis runs in your browser; the entered list is not uploaded.
No. In an independent draw, past absence does not increase a number's probability in the next draw.
Are some lottery numbers luckier than others?
No. Every valid number and every valid combination follows the same official draw rules. Historical frequency describes the sample, not the next result.
Does playing more combinations improve the odds?
Buying more distinct outcomes increases the chance of at least one match only because more outcomes are purchased. Cost rises with them and the game's negative expected value remains.
