Numbers with the lowest total hit count across the full history.
Numbers that hit yesterday are played again today, on the belief they “fall” for several days running.
Take the last two digits of yesterday's special prize and play them again today.
A folk yin-yang pairing: 0-5, 1-6, 2-7, 3-8, 4-9. Whatever hits, you play its “shadow” next. Below is the shadow of the special prize's last two digits.
If no number with tens digit X hit yesterday, you play that whole group today, on the belief that a “mute” digit is about to fire.
Mute tens digits, latest draw
Mute units digits, latest draw
Following 00, 11, 22… on the belief that a long stretch without a double means one is due.
Doubles in the latest draw
Players “nurse” a number that hasn't shown for a while, believing it must be due. The table below measures that belief directly, across the full history.
| Draws since last hit | Hit rate next draw | Trials |

The rate barely moves at any drought length — a number missing for 12 draws has the same chance as one that hit yesterday. This is the gambler's fallacy, measured.
| Position pair | Consecutive run | Today's number |

The folk claim that e.g. “Mondays favour the 3x group”. Below is how often each tens digit appears, split by weekday — darker means more often.
The spread between weekdays is a couple of percentage points and flips around depending on the period — exactly the sampling noise you'd expect, not a “lucky day”.
Look up whatever you dreamt in a “sổ mơ” to get a number — a snake means 32 or 72, a dead person 04 or 84, and so on. This is pure oral tradition with no link to any data, so this page computes nothing for it.
| Number | Draws since last hit | Last seen | Record streak |

The sum forms a bell shape because more digit pairs add up to 9 than to 0 or 18 — that's arithmetic, not a lottery pattern.
The horizontal line is the rate expected under random draws (~23.7% of each year's draws). The closer the bars sit to it, the more ordinary that number is.
