SSQ is the flagship game of China Welfare Lottery. This page covers SSQ rules, per-tier winning odds, return-rate analysis, and an interactive probability simulator that shows — with play money — just how rare a jackpot really is.
Each draw picks 6 of 33 red balls and 1 of 16 blue balls per ¥2 ticket. Draws happen about 3 times a week. Prizes are decided by red-ball matches plus whether the blue ball hits — 6 tiers in total.
Single-ticket odds for all 6 tiers (one standard play). Jackpot odds: 1 / 17,721,088.
| Tier | Match | Odds (1 in) | Prize |
|---|---|---|---|
| 1st Prize | 6 red + 1 blue | 1 / 17,721,088 | ¥5,000,000 |
| 2nd Prize | 6 red + 0 blue | 1 / 1,181,406 | ¥150,000 |
| 3rd Prize | 5 red + 1 blue | 1 / 109,389 | ¥3,000 |
| 4th Prize | 5 red + 0 blue or 4 red + 1 blue | 1 / 2,303 | ¥200 |
| 5th Prize | 4 red + 0 blue or 3 red + 1 blue | 1 / 129 | ¥10 |
| 6th Prize | blue ball only | 1 / 17 | ¥5 |
Long-run return rate ≈ 45% (including the average floating jackpot; a bigger jackpot raises it). Buying more covers more combinations, but per-bet expected value is unchanged.
A single ticket’s jackpot odds are 1 / 17,721,088 — about 0.0000056%. Even broken down by red and blue balls, every tier is a tiny-probability event; the simulator makes that “tiny” feel tangible as real waiting time.
All draws here are locally simulated at random. We are not connected to any real lottery operator and do not provide real draw history. The “history” below is demonstration data from a probability model, for education only — do not bet on it.
The simulator above keeps a rolling “draw ledger” and “life records” — these are generated by the local model, not real draws.
Prediction analysis: each draw is independent, so past numbers never affect the future — there is no method that reliably beats the odds. The sane approach is to treat play as fixed-cost entertainment, use the simulator to understand expected loss (return rate ≈ 45%), and ignore “guaranteed-win” schemes.
