The Math Behind TOTO – Here’s Why It (Statistically) Doesn’t Make Financial Sense To Play

One of the biggest annual prizes available is typically during the TOTO Reunion Draw around Chinese New Year – when the Group 1 prize is at least $5 million. We don’t only have to wait for this TOTO draw though, as there can also be bumper prizes available year-round as Group 1 prize can snowball when there are no winners.

On Monday, two lucky winners shared the $13.2 million Group 1 prize – walking away with a cool $6.6 million each. The winning tickets were purchased from:

Tong Aik Huat – Block 685 Hougang Street 61 #01-160 (1 System 8 Entry)
Singapore Pools Account Betting Service – (1 System 7 Entry)

While we agree that it might be fun to buy “hope” (and we ourselves are among those who buy the odd ticket ourselves), it is also true that Singaporeans are better off abstaining from TOTO bets. So, it could be acceptable to stake a few dollars if you’re in for the thrill, but you should never pour large amounts of money on a regular basis hoping to becoming an overnight millionaire.

In the long-run, you will always lose money. Here’s why.

Recap Of The TOTO Rules

For those who don’t know how to play TOTO, here is quick summary of the key rules.

1) You pick at least 6 numbers between 1 and 49.

2) During each draw, 6 Winning Numbers and 1 Additional Number are drawn.

3) If your chosen numbers match at least 3 of the Winning Numbers, you win a prize. The amount you receive depends on how many of your chosen numbers match the Winning Numbers.

4) Another important caveat is that if more than 1 winner in Groups 1 to 4, prizes will be divided equally among all winners of the group. The prize amounts for Groups 5 to 7 are fixed.

What Are The Odds Of Winning The TOTO Jackpot (Group 1)?

When you play TOTO, you do so in hopes of winning the eye-watering top prize. But what are your odds of doing so? To answer this question, we dusted off our copy of Schaum’s and refreshed our knowledge on Permutations and Combinations.

We need to match all 6 numbers from a possible list of 49. Since the numbers don’t repeat, there is only 1 possible combination that will yield us the top prize.

Thus, C(49, 6) = 1/13,983,816

In other words, the odds of winning are about 1 in 14 million.

To say these are extremely poor odds would be an understatement. Then again, we humans are bad at gauging immensely unlikely events. One way to think about how much value your $1 lottery ticket has is to calculate its Net Present Value.

Net Present Value Of A $1 TOTO Ticket

The actual odds and prize value can only be calculated once sales closes, since 54% of sales in each draw would be added to the existing prize pool.

For this calculation, we assume that the prize pool is $31,578,947 – based on $12 million being 38% of the prize pool and the Group 1 prize value. We also assume we only buy 1 TOTO ticket and ignore other players for now. In other words, this is how much your TOTO ticket is worth if you were the only one playing.

If we multiply the probability of winning by the prize money and sum up the total probable winnings, we will have a Present Value of $76.16. Subtracting the $1 we used to buy our TOTO ticket, we would get a Net Present Value of $75.16.

And if we add up all the probabilities of winning, the chances of actually winning something in any of the groups are 1.9%.

Not bad, isn’t it?

Obviously, though, Singapore Pools does not operate the draw just for you. When you consider other players and how they affect your winnings, your TOTO ticket’s Net Present Value looks very different.

Net Present Value Of A $1 TOTO Ticket (Based On Historical Number Of Winners)

If you recall, the prize money in Group 1, 2, 3 & 4 will be split in the event that there are multiple winners for each group.

Again, it is impossible to calculate the expected value because there is no way to know for certain how many winners there will be in each category. We can, however, use the average of the number of winners from each group in past Hong Bao Draws.

If we take this into account and calculate the present value of our TOTO ticket, we get a very different conclusion:

The expected value has been significantly reduced to $0.62. If we subtract the $1 used to buy our ticket, our Net Present Value is now negative $0.38.

This makes it very clear why it doesn’t make statistical sense to play TOTO?

Ironically, your TOTO ticket’s Net Present Value would be highest at a time when the least players are playing the game. All the other players know that. But because none of the players has perfect information on when equilibrium is reached (where the Present Value of a $1 TOTO ticket is slightly above $1), it is impossible to “game” the system.

Thus, the real winner of every draw remains Singapore Pools.

Have Fun Responsibly

On a lighter note, the participation in TOTO betting should be one of leisure and a topic with friends and family, especially during the festive Hong Bao draw. However, if you are thinking of getting rich by pouring your savings into TOTO draws, we’ve shown you why you will unlikely be successful.

Let’s exercise a Responsible Play mentality and treat TOTO (or any other form of gambling) as a recreational activity and never as a get-rich-quick-scheme or form of “investment”.
