Swiss Lotto Odds Calculator

Swiss Lotto, sold by Swisslos in German-speaking and Italian-speaking Switzerland and by Loterie Romande in Romandy, is 6 from 42 plus a Lucky Number from 1 to 6. Use Tickets for the number of full lines (six main numbers + Lucky Number) on one Wednesday or Saturday draw. A system that expands main numbers still needs a Lucky Number per combination; count real lines, not circled numbers.

Price defaults to 2.5 for the typical CHF 2.50 stake. Keep Jackpot in Swiss francs if Price is in francs. If you convert everything to euros for a trip comparison, convert both. Mixing CHF 2.50 with a euro jackpot will trash EV. Jackpot is the advertised Swiss Lotto jackpot. The pot is smaller than EuroMillions; paste the current Swisslos or Loterie Romande figure.

Main Matches is the 6/42 part. Leave it at 6 for a full main hit. Bonus Matches is the Lucky Number: 1 means you need the correct digit from 1–6 for the jackpot-style path; 0 means you are looking at a main-ball prize that does not require the Lucky Number. Full jackpot in this model is 6/42 × 1/6.

Outputs follow the shared lottery engine: Jackpot Odds, This Prize Odds, chances across Tickets, and jackpot-only EV. Swiss Lotto is combinatorially “easier” than 6/49 because 42 is a smaller pool, but the Lucky Number multiplies the jackpot wall by 6. Compare that honestly to a plain 6/42 without lucky digit, which this game is not.

Fill the form like a Swisslos slip. Tickets = how many CHF 2.50 lines with a Lucky Number marked. Price = 2.5 unless your kiosk receipt differs. Jackpot in francs from Swisslos or Loterie Romande, not EuroMillions. Main Matches = 6 and Bonus Matches = 1 is the jackpot path. Main Matches = 5 with Bonus Matches = 1 is “five mains plus Lucky Number,” a different This Prize Odds line. Main Matches = 6 with Bonus Matches = 0 is the 6/42 hit without the Glückszahl, which is not the advertised jackpot. If you play in Geneva through Loterie Romande, the fields do not change; only the logo on the receipt does.

Swiss Lotto is the national combination lottery of Switzerland, distributed by Swisslos and Loterie Romande depending on region. The matrix is 6 from 42 plus a Lucky Number (Glückszahl / numéro chance) from 1 to 6. Draws are Wednesday and Saturday. A typical line is CHF 2.50, hence the default Price. The smaller main pool is the headline difference versus German 6aus49 or Polish 6/49: C(42,6) is only 5,245,786 before the Lucky Number.

The Lucky Number is a true bonus pool of size 6, drawn 1. That is a larger extra factor than Vikinglotto’s 1-from-5 Viking, and a smaller extra factor than Powerball’s 1-from-26. Full jackpot odds are 1 in 5,245,786 × 6 = 1 in 31,474,716. That is still much easier than EuroMillions and still a serious wall. Marketing that calls Swiss Lotto “the easier jackpot” is talking about the 6/42 main matrix relative to 6/49, not claiming you should expect to win.

Do not confuse Swiss Lotto with EuroMillions, which Switzerland also sells, or with sports betting products from the same operators. Do not confuse Swisslos (the operator in much of the country) with the game matrix. Loterie Romande is the Western Swiss operator, not a different number of balls. Same 6/42 + Lucky Number.

Jackpots are in francs and can roll. This calculator’s EV is jackpot-only, no lower-tier francs, no split model, no withholding. Use it when you want the actual combination identity of Swiss Lotto rather than a vague “Swiss lottery odds” search that might have meant EuroMillions tickets bought in Geneva.

Swiss federal structure is why two logos sell one matrix. Swisslos and Loterie Romande are not competing 6/42 variants; they are regional distributors of Swiss Lotto. Tourists buying EuroMillions in Zürich and calling it Swiss Lotto will misread every output on this page. The Lucky Number 1–6 is closer to Vikinglotto’s tiny Viking pool than to a Powerball, which is why jackpot odds land near 1 in 31.5 million rather than 1 in 5.2 million. CHF 2.50 is a heavy stake relative to that p, which is the about-section moral the EV line will repeat in francs.

Swiss Lotto as Swisslos and Loterie Romande sell it is six from forty-two plus a Lucky Number (Glückszahl / numéro chance) from 1 to 6. Two logos, one matrix: regional distributors, not competing 6/42 variants. Main combinations C(42,6) = 42×41×40×39×38×37 / 720 = 5,245,786. Lucky Number C(6,1) = 6. Jackpot probability is 1/[C(42,6)×C(6,1)] = 1/31,474,716. The main-only 6/42 hit is 1/5,245,786, which is not the advertised top prize. Marketing that calls Swiss Lotto “the easier jackpot” is comparing 6/42 mains with 6/49, then quietly omitting the factor of six. Stake is typically 2.50 Swiss francs, Wednesday and Saturday. EuroMillions sold in Zürich is a different product.

Falling product for 5,245,786: 42×41 = 1,722; times 40 = 68,880; times 39 = 2,686,320; times 38 = 102,080,160; times 37 = 3,776,965,920; divide by 720. Times six lucky digits: 31,474,716. The bonus pool of six is larger than Vikinglotto's five-way Vikingtal and smaller than a ten-way Chance ball. Tourists who buy EuroMillions and call it Swiss Lotto will misread every subsequent identity.

Hypergeometric mains: C(6,m)×C(36,6−m)/5,245,786. Five mains: 6×36 = 216, about 1 in 24,286 on the white balls. Lucky Number hit or miss multiplies by 1/6 or 5/6. Five mains without the Glückszahl: (216/5,245,786)×(5/6). Six mains without lucky: 5/31,474,716. Six mains with lucky: the jackpot.

Independent lines give 1−(1−p)^n with p = 1/31,474,716. Ten lines ≈ 3.18×10^−7. The smaller main pool does not make a ten-line Saturday slip serious coverage of 31.5 million jackpot combinations. Six lines at 2.50 francs against a four-million franc headline: chance ≈ 1.91×10^−7, expected value 6×(4,000,000/31,474,716 − 2.50) ≈ 6×(−2.373) ≈ −14.24 francs.

Expected jackpot value is n×(J/31,474,716 − 2.50). Jackpot-only breakeven wants 2.50×31,474,716 = 78,686,790 francs advertised, far above normal Swiss pots. One and a half million over 31.5 million is about 4.8 cents against 2.50 francs, so about −2.452 per line. The relatively easier 6/42 grid is real; after the Lucky Number and 2.50 francs, jackpot-only expectation is still a deep hole. Keep francs with francs. Keep six. Keep 1-from-6. Keep EuroMillions out of the 31,474,716 denominator.
