Singapore Toto System 7 Explained
A Singapore Toto System 7 entry starts with 7 selected numbers and covers every possible 6-number set that can be formed from those numbers. That means C(7,6) = 7 ordinary combinations in one System 7 ticket. It is a combination format, not a prediction method or a guarantee of any prize.
Quick Answer
System 7 is equivalent to covering all 7 possible ordinary 6-number combinations from 7 selected numbers. Each combination is checked against the Toto Winning Numbers and Additional Number using the normal prize-group rules.
How the System 7 Formula Works
C(n,6) means the number of unique 6-number sets that can be formed from n selected numbers. For System 7, n is 7, so the calculation is C(7,6). There are 7 different ways to leave out one number from a set of 7, which gives 7 ordinary combinations.
Formula: C(7,6) = 7
Meaning: 7 selected numbers produce 7 ordinary six-number entries.
System 7 Combination Example
Suppose the selected numbers are 3, 8, 14, 21, 22, 26, 34. The System 7 entry covers these 7 six-number combinations:
| Combination | Numbers covered |
|---|---|
| 1 | 8, 14, 21, 22, 26, 34 |
| 2 | 3, 14, 21, 22, 26, 34 |
| 3 | 3, 8, 21, 22, 26, 34 |
| 4 | 3, 8, 14, 22, 26, 34 |
| 5 | 3, 8, 14, 21, 26, 34 |
| 6 | 3, 8, 14, 21, 22, 34 |
| 7 | 3, 8, 14, 21, 22, 26 |
How Winning Shares Can Work
A System 7 ticket contains multiple ordinary combinations. Because of that, one System 7 ticket can have more than one winning combination if several of its 6-number subsets match prize-group conditions in the same draw.
Simple worked example
If the selected System 7 numbers include all 6 Winning Numbers plus the Additional Number, one of the 7 combinations would contain all 6 Winning Numbers. The combinations that contain 5 Winning Numbers plus the Additional Number may also qualify under the relevant prize-group rule. Actual payout depends on the official draw result and the published prize share amounts.
This example explains the checking logic only. It does not predict results or imply that System 7 guarantees a prize.
System 7 Cost Behaviour
System 7 represents 7 ordinary combinations. Final ticket cost depends on the current official stake structure and bet mode. Sporela does not hardcode a live ticket price here because cost and sale conditions should be verified with the official operator at the time of purchase.
