# TOTO Calculator: Odds and Prizes for Every System Bet Work out TOTO odds for Ordinary, System Roll and System 7 to 12 bets, and what each bet wins when you match 3 to 6 numbers, using Singapore Pools' game rules. Interactive tool: https://lookup.sg/tools/toto-odds-calculator ## How this works TOTO draws 6 numbers from 1 to 49, then an Additional Number from the remaining 43. A set of six numbers wins if it contains at least 3 winning numbers, and each set only wins its highest prize group. These rules are from the TOTO Game Rules approved by the Gambling Regulatory Authority, in force from 2 March 2026. Odds are exact combinatorics: there are 13,983,816 possible sets of six (49 choose 6). A System N bet covers every set of six inside your N numbers (System 7 is 7 sets for S$7, System 12 is 924 sets for S$924), and a System Roll covers your 5 numbers with each of the other 44 as the sixth, for S$44. The calculator counts how many of your sets land in each group for every possible result. Groups 1 to 4 are shares of the prize pool, which is 54% of the draw's sales net of GST: Group 1 gets 38% (guaranteed at least S$1,000,000), Group 2 gets 8%, Group 3 gets 5.5% and Group 4 gets 3%, split equally among winning shares. Groups 5, 6 and 7 pay a fixed S$50, S$25 and S$10 per winning set. Every draw is independent and no choice of numbers changes the odds.

A System 7 bet (S$7) is 1 in 1,997,688 and a System 12 bet (S$924) is 1 in 15,134. The odds of winning any prize with an Ordinary bet are about 1 in 54. ### How much does a System 7 win if I match 4 numbers? S$190: three sets win Group 5 (S$50 each) and four sets win Group 7 (S$10 each). If one of your other three numbers is the Additional Number, it is 2 Group 4 shares, 1 Group 5 (S$50) and 4 Group 6 (S$25 each), so S$150 plus the two Group 4 shares. ### How much is TOTO Group 7, 6 and 5? Group 7 (3 numbers) pays S$10, Group 6 (3 numbers + Additional) pays S$25 and Group 5 (4 numbers) pays S$50 per winning set. Groups 1 to 4 are not fixed: they are 38%, 8%, 5.5% and 3% of the prize pool, shared among winners. ### How much does a TOTO System 12 cost? S$924, because 12 numbers make 924 different sets of six and each set is a S$1 bet. System 8 is S$28, System 9 is S$84, System 10 is S$210 and System 11 is S$462. ### What happens if nobody wins the TOTO jackpot? The Group 1 prize snowballs to the next draw. If it stays unwon for 4 consecutive draws, it cascades: it is shared among the Group 2 winners of that fourth draw, or Group 3 if there are none, and so on down to Group 7. ## Sources - [Gambling Regulatory Authority: TOTO Game Rules (w.e.f. 2 March 2026)](https://www.gra.gov.sg/api/media/29a5030f-b1f3-4441-92cf-f48651458562/toto-game-rules_2mar26.pdf) - [Gambling Regulatory Authority: Lotteries game rules (Singapore Pools)](https://www.gra.gov.sg/licenses-approvals/regulatory-approvals-for-other-gambling-operators/games/game-rules/lotteries-game-rules-(singaporepools)) - [National Council on Problem Gambling: how to find help](https://www.ncpg.org.sg/learn-more/about-problem-gambling/how-to-find-help-for-problem-gambling) --- Source: Lookup (https://lookup.sg) · Data as of October 2026 · Listings compiled from Singapore government open data (data.gov.sg), OneMap and Overture Maps places.
