Most Common Irish Lotto Numbers — Full Frequency Analysis

With 47 possible numbers and 6 drawn per game, each number has an expected frequency of approximately 12.8% per draw. Over 2,000+ Wednesday and Saturday draws, each number would be expected to appear roughly 250–280 times in a perfectly random game.

The most frequently drawn Irish Lotto numbers historically have included 38, 23, 44, 11, and 34 — though these rankings shift with every new draw. The least drawn numbers have tended to cluster at the extremes of the range, particularly in the low single digits and around 40–47.

Current exact frequency counts for all 47 numbers are on our live Irish Lotto statistics page, updated within 2 hours of every Wednesday and Saturday draw.

The Bonus Ball is drawn from the same pool of 47 numbers as the main balls, but is only relevant for certain prize tiers (e.g. matching 5 main balls + Bonus Ball). It is not included in the main 6-ball draw.

Because the Bonus Ball is a single draw from 47 numbers, each number appears as Bonus Ball approximately once every 47 draws on average. Historically, the Bonus Ball distribution is closely aligned with the main ball distribution — the same pool, the same randomness.

Our statistics page shows Bonus Ball frequency and overdue Bonus Ball numbers updated after every draw.

Irish Lotto analysis shows that numbers in the mid-range (approximately 15–35) have historically appeared slightly more often than the extremes, though this pattern is within the expected statistical noise for a random draw of this size.

For strategy purposes, most experts recommend spreading your picks across the full 1–47 range rather than clustering in any section. The Lottery Analyser scores spread as one of 9 strategy dimensions and flags combinations that are too clustered.

Across all historical Irish Lotto draws, the most common odd/even split for the 6 main balls is 3 odd / 3 even or 4 odd / 2 even (and its mirror 2 odd / 4 even). All-odd or all-even combinations have appeared in a small minority of draws — roughly 3–4% of the time.

For a 6-ball game from 47 numbers (24 even, 23 odd), perfect balance is statistically the most likely single outcome, though imbalanced splits are still common enough that you should not completely exclude them.

The sum of the 6 winning Irish Lotto numbers typically falls between 120 and 200 in approximately 70% of draws, with an average sum of around 145. Combinations with very low sums (e.g. all numbers below 20, sum under 80) or very high sums (e.g. all numbers above 35, sum over 220) appear rarely.

Use this as a sanity check on your picks: if your 6 numbers add up to less than 100 or more than 220, consider adjusting one or two numbers to bring the sum closer to the historical range.
