Latest drawMonday, 12 October 2026
SourcesOnly Primary (commercial feed) reported this draw, so there is nothing to check it against. Settled 13 Oct 2026, 03:16 UTC.
4 numbers from 1–31, plus 1 from 1–16. 3,843 draws held here since 2016-04-03 — 727 under the current rules.
Big Sky Bonus changed its number pool then, which started a new era. Only the 727 draws since count towards number statistics — mixing draws from before a rule change would make any frequency meaningless.
This draw, read by every tool
What the site’s explorations say about the numbers drawn on 12 October 2026 — each beside what chance predicted. None of it says anything about the next draw.
Scored 63 of 100 across six shape features — more typical than about 73% of every possible ticket.
Times drawn before — chance expected 94 of each
Every number was expected about that many times after 726 draws, and they scatter around it. Warm means more than expected, cool means fewer — and a cold number arriving is exactly what cold numbers do.
Frequency Explorer →Shares 3 of 4 numbers (7, 20, 22) and 0 of 1 stars with the draw of 26 June 2026 — its closest relative in 726 draws. Chance gave a match this close a 92% likelihood somewhere in that history.
From the draw just before (11 October 2026): 7 carried over. Chance says 44% of draws repeat at least one number. Stars: none repeated (6% expected).
Carry-over / Déjà Vu →The numbers add up to 68 — the 58th percentile of all possible tickets, around a middle of 64. Side-by-side numbers: 19–20. 35% of draws have at least one such pair.
Sum Distribution →19 had not appeared for 5 draws. A number waits about 8 on average, and a wait this long was not a signal — the machine has no memory of it.
Gap & “Overdue” Tracker →A line like this is played about 1.5× as often as an average ticket — more popular than most. At 30 million tickets sold, a winner on these numbers would keep about 0% of the jackpot.

Every tool, for this game
Each one opens with Big Sky Bonus already selected. The line under every title is true of this game’s rules right now — not a promise about its next draw.

In 727 draws every number is expected about 94 times, and a ball favoured by more than 38% over its share would already have shown — see which ones strayed, and how far chance allows.

A number waits 8 draws on average; 5% of the time it waits 23 or more. It is never “due”.

The 4 numbers add up to about 64, give or take 17. Most tickets sit in that bell — and so do most draws.

34.9% of draws contain two numbers side by side. That is the rules talking, not luck.

465 possible pairs, each expected together 9.4 times so far — and about 5 will look “special” by chance alone.

All 31 numbers as a constellation of who appeared with whom — indistinguishable from a shuffled sky.

44% of draws repeat a number from the draw before. A whole draw repeating: 100.0% likely by now.

Sorted, the numbers sit about 6.4 apart on average — and every “spread” you can name is exactly as likely as every other.

It takes about 30 draws for every one of the 31 numbers to appear at least once. The last few are the slow ones.

503,440 possible tickets. Every one has a face — and a typicality score you can look up.

Seven independent tests of randomness run live against all 727 draws. Any of them can fail; watch whether they do.

The lowest number lands near 6, the highest near 26. Position is a property of sorting, not of the balls.

4/31 rescaled onto the same axes as every other game here. One law, many machines.

Six documented cases of a beaten lottery. Not one involved patterns in past draws.

What the world believes about 7, 8, 13 and 17 — and what every machine says back.

At 30 million tickets, an average line keeps about 0% of a jackpot it wins. Unpopular numbers keep more — and still lose money.

A full wheel of 10 numbers here is 210 tickets. A guarantee is real; a profit is not.

Five folk claims about 4/31 games, each answered with the closed form that kills it — never a tip for the next draw.

Lock a past-only rule, score it on later draws, and compare every hit with the exact 4-of-31 overlap law.

Every one of 31,465 possible draws receives a unique rank; a fair stream fills that line uniformly.

Monitor all 31 balls after every draw without optional-stopping tricks; evidence 20× is the predeclared 5% alarm line.

Compare adjacent eras as complete 4-ball sets, so no “interesting” number or summary is chosen after looking.

Shuffle while preserving all 31 ball totals and every draw size; only pair structure beyond solo frequency remains.

Odd/even is modulo 2. Turn the dial through 10 and compare each colour recipe with its exact finite-pool law.

Prize-table winner counts can infer ticket exposure and test whether this game follows the literature-based crowd model.

Benchmark six detectors at 100 and 400 synthetic 4-of-31 draws: false alarms beside power, before interpreting history.

Resolve this 4-of-31 history into single-ball, pair-after-single, and all-degree structural bands.

Test whether whole-draw ranks, successive overlaps, or spacings compress more than shuffled chronology.

Let hot, cold, overdue, and repeat models learn on discovery draws, then score one locked challenger on untouched 4-of-31 outcomes.

Monitor complete 4-ball draws with conformal evidence that remains valid whenever the watch is inspected.

Map every completed wait through its geometric 4/31 law, then test the common 0–1 residual ruler.

Every number in this pool is inside 1–31, so a date reaches all 31 of them and the birthday crowd has nowhere to concentrate.

Read what this game paid back across 727 draws, and every night it paid out more than it took — always visible only afterwards.

Its jackpot is one chance in 503,440 today — see every rule change that made it so, and by how much each one lengthened the odds.

Where a game publishes which drum and which set of balls drew it, each set is tested on its own here — the only place a physical fault could hide.

Six ways of splitting the calendar — weekday, month, part of the month, holiday, slot, machine change — each asking whether this game's draws differ from the rest of their own history.

Every game this site holds, put through the same three fairness tests — this one among them, with a false-discovery pass across the whole board.

Replay this game from the start and record everything that ever passed 3.15 standard deviations — the threshold 31 numbers at once demands — then read what happened to it next.

Open the studio on this game’s own 4-from-31, then move one number and watch the 1-in-503,440 jackpot, the sum curve and the break-even prize move together.

Three simulated machines. Which would you investigate?

Find a miracle in a fair archive, then count the searches that found it.

Does the estimated preference for birthday numbers change over time or with jackpots?

One hypothetical routine, thousands of lives, and the full spread of outcomes.

Combine primes, squares, Fibonacci numbers and sums. Count how much of chance your recipe describes.

Find equal steps and mirror pairs in history, then grow a fair comparison.

HH and HT each have a one-in-four chance in two flips. Why does one take longer to arrive?

Give fair numbers the wrong baseline and watch an innocent pattern appear.

From a 1767 paper to every possible arrangement of consecutive runs.

This is a without-replacement ball game; the Digit Laboratory is for Pick 3 and Pick 4.
Not for this game
The Chernoff Map reads the straight tier of a digit game, which counts tickets on one exact number; a ball game has no such row.
Not for this game
This game draws once a day, so it has no second draw to compare its first with.
Not for this gameWhat the top prize has been, draw by draw. It climbs while nobody wins and drops to the floor when somebody does — the sawtooth every rollover game draws.
Happenedwhat chance predicts
Completed waits between wins, against the geometric law those waits follow if every draw is an independent chance at the jackpot. The law takes its one parameter from the waits themselves, so this compares shape, not level.
