Weekday Windfall Number Frequency Analysis
Weekday Windfall (formerly Monday & Wednesday Lotto) draws 6 numbers from 45 three times per week — every Monday, Wednesday, and Friday. With the same 6/45 format as TattsLotto, the mathematical properties are identical: each number has a 13.3% expected frequency per draw. Our analytics page covers every draw since January 2008, including the 2024 rebrand that added Friday as a third draw day, giving us one of the largest 6/45 lottery datasets in Australia.
The frequency chart displays all 45 numbers ranked by how often they have appeared across thousands of Monday, Wednesday, and Friday draws. Over this many draws, the distribution is remarkably flat — confirming the genuine randomness of the draw process. Short-term deviations are visible when you switch to a recent window of 50 or 100 draws, revealing the natural variance that creates hot and cold number patterns.
Hot and Cold Numbers
Because Weekday Windfall draws three times per week, 50 draws spans roughly 17 weeks — a shorter real-world window than TattsLotto's 50 weeks from the same draw count. This means hot and cold patterns update more dynamically. Our heat map shows each number's deviation from expected frequency, colour-coded to make above- and below-average numbers immediately visible.
The rapid draw cadence makes Weekday Windfall particularly interesting for tracking how quickly hot and cold streaks form and dissolve. A number that appears 4 times in 10 draws (40% frequency, triple the expected 13.3%) would be classified as extremely hot — but over the next 40 draws, regression to the mean typically brings it back toward expected levels. This natural cycle is clearly visible in our timeline analysis. For more on what these patterns mean, visit our hot and cold numbers guide.
Comparison with TattsLotto Statistics
Since both games use identical 6-from-45 mechanics, comparing their frequency patterns reveals how randomness behaves across parallel systems. Numbers that are hot in Weekday Windfall are not necessarily hot in TattsLotto, because each game uses its own independent draw machinery. This comparison is a powerful demonstration that lottery outcomes are genuinely random — our TattsLotto analytics page shows the same statistical tools applied to Saturday draws for direct comparison.
The 2024 Rebrand and Friday Draws
When Monday & Wednesday Lotto became Weekday Windfall in 2024 with the addition of Friday draws, the draw frequency increased by 50%. Our analytics account for this by allowing you to filter by time period, ensuring you can compare like-for-like when examining frequency trends across the format change. The game mechanics and odds remained identical — only the name, branding, and draw schedule changed. Friday draws use the same 6/45 barrel system as Monday and Wednesday, meaning all three draw days are statistically interchangeable.
Common Pair Analysis
With 6 numbers drawn from 45 per game, each draw produces 15 unique pairs from 990 possible combinations. Our pair analysis identifies which two-number combinations appear together more often than expected. At three draws per week, pair data accumulates faster than for Saturday-only TattsLotto, giving our analysis a larger sample size over the same calendar period. We rank all 990 pairs by their frequency ratio and highlight the most statistically notable combinations.
Overdue Number Detection
In Weekday Windfall's 6/45 format, the average gap between appearances for any single number is approximately 7.5 draws — identical to TattsLotto. However, because Weekday Windfall draws three times per week, 7.5 draws represents roughly 2.5 weeks of real time rather than TattsLotto's 7.5 weeks. Numbers absent for 20+ draws (approximately 7 weeks) are statistically unusual. Our deviation tracker flags numbers that exceed 2 standard deviations from their mean gap.
Odd/Even and Sum Range Patterns
Historical Weekday Windfall draws show the same distribution as TattsLotto: the most common odd/even split is 3/3 (roughly 33% of draws), followed by 4/2 and 2/4 splits (~27% each). All-odd or all-even draws occur in fewer than 1% of draws. The sum of 6 winning numbers typically ranges from 100 to 180, with a median of approximately 135. These patterns are consistent with random draws from 45 numbers and serve as useful benchmarks for evaluating number selections.
