Probability of Winning Lotto Max (Canadian Lottery)

In Canada, Lotto Max is a uniquely structured lottery with a prize cap of 50 million dollars. If the jackpot exceeds 50 million, the excess amount is awarded in parcels of one million dollars during the "Maxmillions" draws. For example, if the Lotto Max jackpot reached 56 million dollars, there would be one main drawing for the 50 million dollar prize, and then six Maxmillions drawings worth one million apiece.

During each drawing, officials randomly select seven distinct numbers from 1 to 49, and then another bonus number. You do not select the bonus number on your ticket, you only select the seven main numbers. A Lotto Max ticket costs $5 but allows you to make three separate seven-number selections. This means the actual cost of a single selection is only $5/3 = $1.67, less than the $3 cost of a single-play Lotto 6/49 ticket.

The main prize is awarded to the ticket holder(s) who matches all seven main numbers. Lower-tier prizes are awarded for matching 6/7 plus the bonus, 6/7 but not the bonus, and other partial matches. There is no special prize for getting 7/7 plus the bonus since you do not select any bonus numbers on your ticket. In order to win a Maxmillions runoff drawing, you must match 7/7 on the additional drawings. There are no lesser prizes awarded for partial matches on a Maxmillions drawing.

Odds of Winning Lotto Max

The odds of winning the main jackpot depends on the total number of possible lottery ticket combinations. Since Lotto Max is structured as a 7 out of 49 game, the number of different combos is


= 432938943360/5040

= 85,900,584

This is about 6 times the number of possible tickets in Lotto 6/49. The odds of a single selection winning the Lotto Max jackpot are 85900584 to 1, however, since each ticket gives you three picks, the true odds are 85900584 to 3, or equivalently 28633528 to 1.

In probability terms, the likelihood of having a 7/7 match on your Lotto Max ticket is 0.000000034924. As a percent, this is 0.0000034924%, about half as likely as winning Lotto 6/49. This probably explains why in Canada, Lotto 6/49 is still the more popular of the two lotteries.

Manual Selection or Quick Picks?

When you buy a Lotto Max ticket, you can either let the computer choose all three seven-number selections for you at random, or you can choose one of the selections yourself and let the machine pick the other two. You do not have the option to choose the numbers for all three selections yourself.

Lesser Lotto Max Prizes and Their Odds

The jackpot is 87% of the prize fund. The rest of the prize fund is awarded to ticket holders whose numbers partially match the winning numbers. Here is a table with the odds of winning lesser prizes in Lotto Max drawing.

Partial Match
What You Win
6/7 + bonus
1 / 4090506.5
your share of 4% of the prize fund
1 / 99768.7
your share of 4% of the prize fund
1 / 1583.96
your share of 5% of the prize fund
1 / 71.6
3/7 + bonus
1 / 77.08
1 / 8.42
free ticket

In Canada, lottery prizes are tax free and can be received in installments or as a lump sum. The odds of winning a Maxmillions runoff drawing are the same as the odds of making a 7/7 match on a 3-play ticket. The more Maxmillions drawings there are, the better your chances of winning. If there are 10 runoff drawings, your chances are 10/28633528. But if there happen to be 47 runoff drawings, your chances increase to 47/28633528.

does having more maxmillions increase your odds? A friend told me because this week has 50 maxmillions that your odds of winning go from 1:28.6 million to 1: 572 670. I don't understand how having more draws would increase your odds? Could you provide any clarity?

Thanks for the great question Jordan. Having more Max Millions draws for the excess money in pool doesn't increase your chances of winning the main prize (whose value is capped, thus creating the excess), but it does increase your overall chances of winning any prize.

Say you bought a ticket and your numbers didn't match the main prize drawing, but there was enough excess for one or more Max Millions drawings. For each of these drawings they select an entirely new set of numbers at random, so you still have a chance to win some of the excess, which is parceled out by the million. The more of these drawings there are, the more chances you have to win one of them.

Thanks for the reply. This is where I get confused. So when I buy my 5 dollar ticket my odds of winning the jackpot is 1:28.6 million. If they are doing separate draws for all of the maxmillions draws how do your odds become better? I could see your odds increasing a bit because of more maxmillions but I cannot see the odds being 50 times better. Is it a lower ratio or do you just divide the 28.6 million by the amount of maxmillions?

Your chances of winning any particular drawing are still abysmal, but if you get N tries, your chances are N times better. Say I pick a number from 1 to 10 and you have to guess it. If I give you one guess, your chances are 1/10 = 0.1. But if I give you two guesses your chances are 2/10 = 0.2. (If I gave you 10 guesses, your chances of getting it would be 10/10 = 100%.)

The probability of matching 7/7 with a three-selection ticket is so minuscule to begin with that multiplying by N doesn't do all that much to improve your odds. But it is some improvement.

One other thing to consider is that when ticket sales reach the volume necessary to create a lot of runoff maxmillions drawings, it means the chances that some people bought the same numbers also increases. And according to the lottery website, if more than one person holds a matching ticket for a max millions drawing, they have to share that $1,000,000.

when the jackpot surpases the population of canada, why don't they just give everyone one million dolllars?

Well, the jackpot has never surpassed 35,160,000 times $1,000,000 = $35,160,000,000,000, but I suppose when the jackpot goes over $35,160,000 they could give everyone a loonie (Canadian $1 coin).
