Singaporeans dreaming of getting filthy rich for not doing much are looking forward to Thursday, May 17.

This is because the estimated S$8 million Toto jackpot prize has snowballed to its fourth and final round.

This snowballing occurs when there has not been any Group 1 prize winners for three consecutive draws.

A Group 1 prize occurs when a winning ticket matches all six winning numbers.

The fourth round then puts an end to the accumulated prize money through something known as "cascading".

This means that even if there is no Group 1 prize winner in the fourth round, the S$8 million will "cascade" to the next prize group (e.g. Group 2) and be split equally among the winner(s).

Winning odds

Bets start from a minimum of S$1 for an ordinary bet, which gives you a 1 in 13,983,816 chance of winning (if your eyes blur that's almost 14 million). In this scenario, you would have to pick all six of the winning numbers to qualify for jackpot.

However, should you choose to buy system bets, your chances increase, well, not exponentially, but somewhat significantly.

Naturally, your bet money will increase as well.

System 7, for example, allows you to pick seven numbers instead of six, thereby giving you seven winning combinations instead of one. This gives you an estimated 1 in 2,000,000 chance for S$7.

This goes all the way to System 12, where you end up paying S$924 for a 1 in 15,134 chance chance of winning the Group 1 prize jackpot.

Good luck for this round.

In other words, don't bother. You will most likely not win.
