La matematica del #superenalotto
📚 Main topics
- The game and its prizesThe video reviews the classic Superenalotto rules: choose six numbers from 1 to 90, then match drawn numbers to win, with a bonus number enabling the 5+1 prize. Prizes vary, so the video uses average payouts for its calculations. 1:40
- Expected valueExpected value combines each possible payout with its probability to estimate the average return. The die example has an average payout of €3.50, while a €1 bet on red or black in French roulette returns about €0.97 on average. 4:37
- Superenalotto probabilitiesThe total number of possible six-number combinations is calculated using combinations, which disregard the order of the numbers. The video then counts the favorable outcomes for each prize tier, including how the bonus number affects 5 and 5+1. 12:59
✨ Key takeaways
- The average return is below the stakeUsing the published odds and average prizes, a €1 Superenalotto play returns about €0.75 on average, meaning an average loss of €0.25 per play. 10:13
- Why published odds differThe video says some published probability figures are easier to understand but are approximations of the exact values. Using the exact probabilities changes the overall expected return very little. 22:03
🧠 Lessons learned
- Combinations ignore orderWhen choosing numbers for a palette or lottery ticket, different selection orders can represent the same combination. Divide ordered selections by the number of possible orderings to count unique outcomes. 12:59
- An expected loss is an average, not a guaranteeIndividual players can win, but over many plays the average return is lower than the amount wagered. 11:51
🏁 Conclusion/next steps
- Playing for excitementThe video’s advice not to play means recognizing that the game is against the player’s odds: a ticket buys the excitement of possibly winning, but loses on average. 23:08

0:00 Hi! And welcome back to the MATHsegnale. Surely you would have seen titles like these or if you haven't seen them most likely you would have heard about them, about the millionaire lottery winnings you would have probably talked to someone or you would have had the opportunity to compare you by hearing the most disparate strategies. on what is the best way to play and on how many have found a way to win. It has often happened to me. As a math student and even after I was told just
0:32 "Ah! Since you are a mathematician, why don't you tell me how to win the lottery ?!" Net of the obvious answer that if I knew how to win the lottery, I would win the lottery and, yes, I could even tell you but at that point it would no longer make sense; the answer I gave was "Don't play!". But in what sense "don't play"? Why do I have to answer "Don't play"? There are people who have won, why should I tell you "Don't play"? In what sense does it not suit you? This is what we will try to explain today, but before starting
