Tattslotto system play lets you enter more combinations in a single draw by picking more numbers than the standard six. In a System 9 entry, for example, you choose nine numbers, and every possible six-number combination from those nine is automatically entered. That’s 84 combinations in one go instead of one.
Covering more of the combination space costs more money, and winning the jackpot is not guaranteed no matter how many combinations are entered.

A Letter from a Tattslotto System Player
Someone wrote to me about their experience with Tattslotto system play:
Hi Edvin,
I’m in Australia and play Tattslotto using System 9 every Saturday. I’ve been playing up to 3 x each week since 2015. I’ve had four and three straight numbers a few times but can’t crack 5, 5 + 1 Supp, or six straight Numbers! I don’t want to give up after almost 7 years.
The math behind Tattslotto system play doesn’t change with time. What the numbers show is worth understanding clearly.
Tattslotto System Play Is a Lottery Wheel
A Tattslotto system entry is a covering strategy, more commonly called a lottery wheel. You pick a larger set of numbers, and every valid six-number combination from that set gets entered into the draw.
With a System 9 entry, you’re choosing nine numbers. From nine numbers, you can form 84 distinct six-number combinations.1 Playing all 84 improves per-draw probability compared to a single ticket:
84/8,145,060 ≈ 1/96,965
That’s roughly 1 in 97,000 instead of 1 in 8 million. A real difference in coverage. Still a long shot by any reasonable measure.
The drawback is cost. Every combination in a system entry is a separate ticket. Eighty-four combinations means eighty-four times the spend. A System 10 entry produces 210 combinations. The numbers grow fast, and the budget has to keep up.
What System Play Does and Does Not Do
More combinations in a draw means more of the outcome space covered. That is the straightforward upside of Tattslotto system play. The expected value of each combination remains negative, and no number of entries changes that.
Running a random process with long odds for an extended period produces results that reflect those odds. Long losing runs are a normal property of random games with low per-ticket probability. Past results in an independent random process do not affect future draws.
Smaller systems such as System 7 or System 8 involve fewer combinations and lower cost per draw compared to System 9 or System 10. A syndicate distributes the cost of a larger number of combinations across multiple participants, which reduces individual spend while maintaining collective coverage. These are mathematical descriptions of coverage options, not recommendations.
Combinatorial Composition and the Frequency Ratio
Most Tattslotto system play guides don’t look at what happens when you analyze the combinations themselves using combinatorial probability.
A System 10 entry gives you 210 combinations. When those 210 are analyzed using the Lotterycodex combinatorial framework, most fall into occasional, rare, or extremely rare composition groups. Only a small number fall into the prevalent group based on their long-run frequency ratio under the law of large numbers.
In Lotterycodex, I use “frequency ratio” rather than “odds” when describing how often a combinatorial composition appears across many draws. The reason is straightforward: “odds” is typically understood as the odds of winning or losing, which doesn’t describe what is being measured here. Frequency ratio describes the long-run relative prevalence of a combinatorial composition group within the total outcome space, without implying prediction or control over any individual draw.
I developed the Lotterycodex combinatorial classification system through independent research beginning in 2017. The framework partitions the number field into four groups, LOW-ODD, LOW-EVEN, HIGH-ODD, and HIGH-EVEN, and uses those partitions to classify every possible combination by its combinatorial composition. From there, each composition group can be compared by how many combinations it contains relative to the full outcome space, which determines its long-run frequency ratio under the law of large numbers.
The Lotterycodex combinatorial framework makes this distribution visible. From those 210 combinations in a system entry, the ones that belong to the prevalent frequency ratio group can be identified. The remaining combinations belong to occasional, rare, or extremely rare groups, which under the law of large numbers appear less often across large numbers of draws because fewer total combinations exist in those groups.
No combination can be predicted in any single draw. Every specific combination in Tattslotto carries the same single-draw probability as any other. What differs is the long-run frequency at which different combinatorial composition groups appear, and that difference comes entirely from how many combinations belong to each group, not from luck or intuition.
