Rules

Points have no cash value. There are no deposits, no withdrawals, and no prizes. You cannot win or lose real money here, and nothing on these pages is a financial product. This is a forecasting game, not a betting service, and it is not regulated as one.

Every market asks a yes-or-no question about tomorrow’s weather. You buy YES or NO shares. Each share pays 100 points if it is right and nothing if it is wrong.

Prices are set by an automated market maker, so there is always someone to trade against. A share priced at 30 points means the crowd thinks there is a 30% chance — the price and the probability are the same number. Buying pushes the price your way.

Everyone starts with 10,000 points. Positions are held to settlement; selling early is not available yet.

Markets close at midnight local time, before the day they are about to describe. This is deliberate — if you could trade while the weather was happening, a radar tab would beat forecasting.

The next morning, each market settles against the Open-Meteo historical archive, and nothing else. If the archive has not published yet, the market stays pending and retries. It is never settled from a different source, because sources disagree by a tenth of a degree and that is enough to flip a result.

Thresholds are set from the forecast so each market opens near a 50/50 split, not to dodge the line — Open-Meteo reports at a tenth of a degree, so a reading can land exactly on 24.5°C, exactly on 45 km/h, whatever the threshold is. When it does, the market resolves NO: “top 24.5°C” and “above 45 km/h” mean strictly more than the number, not equal to it, so an exact match doesn’t win.

Ranked by return on your starting points, not raw total, and you need at least 10 settled markets to appear. Both rules exist to stop someone farming the top spot with fresh accounts.

There are no top-ups and no resets. If your balance hits zero and you hold no open positions, that account is finished — you start again with a new username and a clean record. Holding an unsettled position that might still pay out does not count as being out.
