The rules

A thousand points a day. Five hundred for the lines you set, five hundred for the calls you make.

The round

Five rounds a day, and every one asks you to do both jobs.

• Set a line. You are given a player and a stat. Put the line as close to the real number as you can.
• Take a line. Call over or under on a line somebody else set earlier.

Scoring

Lines you set: up to 100 each, for how close you got.

• within 10% — 100
• 25% off — 75
• 50% off — 50
• 75% off — 25
• 100% off or worse — 0

It slides the whole way, so there is no edge to fall off — 30% off is 70, 40% is 60, 90% is 10. Every percent closer is worth something.

Calls you make: 100 for calling it right, 0 for calling it wrong.

Asking for help

If you have no idea at all, you can ask for the average of the lines other setters have placed on that item — or, when calling, the share of takers who went over. It is where people have been guessing, not the answer.

Using it takes a quarter off what that line or call can earn.

The clock

Thirty seconds to set a line, twenty to call one. Nothing starts until you tap Start.

• A line you never set is worth 0. Only the button sets one.
• A call you never make is a miss, not a guess.
• The clock does not pause. Close the page and come back and you get whatever is left of it. Come back after it has run out and the round is gone.

In a head to head, a line you run out of time on is filled by the setters’ average so your opponent still has five to call. It scores you nothing.

The belt

One player in the whole game holds it, and they are the OddsFather. You take it off them; you cannot be given it.

The power rankings

Your rating is your best 7 scores out of the last 10 days.

• A day you do not play counts as 0.
• Your worst three days are dropped, so three you miss cost you nothing.
• Miss more than three and the zeros start counting.
• Playing more can only help you.

Every day the oldest day drops off the back and the new one joins, so the ten are always the last ten.

Only the daily counts. Practice and head to head decide nothing here. You need a display name to appear — the daily asks for one after your first set.

Getting a title shot

The #1 contender is whoever is top of the power rankings, not counting the champion. It is not a ticket you keep — lose the top spot and you lose the shot, and hold it and you keep getting them.

The power rankings lock at midnight on Tuesday and Saturday. Whoever is top then gets that shot, so playing on Wednesday or Sunday cannot change who is already in it. A set counts for the day it was dealt, so finishing Tuesday night’s daily after midnight still counts for Tuesday.

Title matches

Made by the game on Wednesdays and Sundays. You cannot ask for one, and there is never more than one at a time.

It is an ordinary challenge — five lines and five calls each — and it runs until the next title day. Whoever has not played their half by then loses it. A champion who does not turn up is stripped; a challenger who does not turn up leaves the champion with it.
