How a Saturday Lotto system works
Saturday Lotto draws eight numbers from a barrel of 45. Lotterywest’s game page explains that the first six are the winning numbers and the last two are the supplementaries. A standard game is six numbers, and the minimum standard entry is four games, $3.80 in WA.
A system entry lets you choose more numbers and plays every six-number game among them. A System 7 is 7 games, a System 8 is 28 and a System 9 is 84. That’s the maths, not a mood: each extra number multiplies the combinations.
Systems 4 and 5 run the other way round. You choose 4 or 5 numbers, and the entry covers every way to complete the game from the rest of the barrel. That comes to 820 games for a System 4 and 40 for a System 5.
Saturday Lotto systems price list
A System 8 costs $26.65 in WA. Here’s the table, from Lotterywest’s Saturday Lotto price list checked on 27 September 2026.
| System | Numbers you choose | Games | Price in WA |
|---|---|---|---|
| System 4 | 4 | 820 | $780.65 |
| System 5 | 5 | 40 | $38.10 |
| System 7 | 7 | 7 | $6.65 |
| System 8 | 8 | 28 | $26.65 |
| System 9 | 9 | 84 | $79.95 |
| System 10 | 10 | 210 | $199.90 |
| System 11 | 11 | 462 | $439.80 |
| System 12 | 12 | 924 | $879.65 |
Divide any price by its games and you get about $0.95 a game, the same rate as standard games in the same list, where 10 games cost $9.50. A system carries no discount and no surcharge, and Lotterywest charges the same in store and online.
What the money buys is coverage. A System 8 turns 8 numbers into 28 games, so a draw that hits several of your numbers can pay several games at once.

What a System 8 wins
First, the six divisions and their odds per game, as Lotterywest publishes them.
| Division | You need | Odds per game |
|---|---|---|
| 1 | 6 | 1 in 8,145,060 |
| 2 | 5 + 1 supp | 1 in 678,755 |
| 3 | 5 | 1 in 36,690 |
| 4 | 4 | 1 in 733 |
| 5 | 3 + 1 supp | 1 in 298 |
| 6 | 3 | 1 in 53 |
| Any prize | 1 in 42 | |
Now the System 8. The table counts its winning games for each outcome, using those division rules.
| Winning numbers among your 8 | None of the others is a supplementary | One of the others is a supplementary |
|---|---|---|
| 6 | 1 × Division 1, 12 × Division 3, 15 × Division 4 | 1 × Division 1, 6 × Division 2, 6 × Division 3, 15 × Division 4 |
| 5 | 3 × Division 3, 15 × Division 4, 10 × Division 6 | 1 × Division 2, 2 × Division 3, 15 × Division 4, 10 × Division 5 |
| 4 | 6 × Division 4, 16 × Division 6 | 6 × Division 4, 12 × Division 5, 4 × Division 6 |
| 3 | 10 × Division 6 | 6 × Division 5, 4 × Division 6 |
We counted these from the division rules. Lotterywest publishes its own prize table for every Saturday Lotto system, linked under Sources. Each winning game is paid the dividend for its division in that draw, and those dividends are on the Saturday Lotto results page after each draw.
Your odds with a system
Each game keeps its odds: 1 in 8,145,060 for Division 1. A system gives you more games, so the whole entry’s chance is that figure divided by the games it holds.
| System | Games | Division 1 odds for the whole entry |
|---|---|---|
| System 7 | 7 | 1 in 1,163,580 |
| System 8 | 28 | 1 in 290,895 |
| System 9 | 84 | 1 in 96,965 |
| System 10 | 210 | 1 in 38,786 |
| System 11 | 462 | 1 in 17,630 |
| System 12 | 924 | 1 in 8,815 |
Because 8,145,060 divides evenly by each of these game counts, the figures are exact. For comparison with other games, the Oz Lotto odds page sets Saturday Lotto next to Oz Lotto, Powerball and the daily games.
A System 8 and 28 standard games sit at the same rate of about $0.95 a game. What differs is how the games relate.
The system’s 28 games all come from the same 8 numbers, so they rise and fall together. A draw with three winning numbers among your 8 pays 10 games at once. A draw with two or fewer of your 8 among the winning numbers pays none of the 28.
Systems 13 to 20
Lotterywest says Saturday Lotto systems are available up to System 20, and its FAQ lists Systems 4 to 5 and 7 to 20. The price list stops at System 12, so we can’t give a WA price for anything bigger. The number of games is simple combination maths:
| System | Games |
|---|---|
| System 13 | 1,716 |
| System 14 | 3,003 |
| System 15 | 5,005 |
| System 16 | 8,008 |
| System 17 | 12,376 |
| System 18 | 18,564 |
| System 19 | 27,132 |
| System 20 | 38,760 |
Sales close and where to buy
Lotterywest closes Saturday Lotto sales at 6:00 pm AWST. That’s 8:00 pm AEST, or 9:00 pm AEDT in NSW, Victoria, the ACT and Tasmania once daylight saving starts on 4 October. Lotterywest’s guide lists Division 1 at an estimated $6 million, with Superdraws and Megadraws offering more.
In WA, Lotterywest’s prices above apply at retailers and online, and each draw is also on Saturday Lotto results for WA. We couldn’t check prices outside WA, because The Lott’s site doesn’t open from our location. Oz Lotteries doesn’t sell to WA or Queensland residents.
Oz Lotto systems run up to System 19, and the Oz Lotto system price list sets them out the same way.
