The weekly, lottery-style stock draw
Wattball is a weekly draw played like a lottery, with the market as the machine. Fill a six-ball ticket — one pick from each chamber — then Friday’s best performer in every chamber comes up as a winning ball. Match more, score more.
Who built this
Wattball comes out of three different rooms: the trading desk, the lecture hall and the startup trenches. The game is how you practise the judgment none of them hands you on its own.

Badges & rankings
Points are only half of it. Badges mark the weeks you actually did the work — a perfect six, a Megawatt call, five Daily Calls in a row — and your rank moves against the field the moment Friday’s balls land.

Season 1 ladder
rank moves after every draw
Season points come from matched balls, match bonuses and Daily Calls — and every rung you clear adds a badge to your case.
The way up · Match
Every ball you match pays its own points, and the bonus ladder on top climbs all the way to 10,000 for a perfect six.
The way up · Call
One Daily Call before 9:30 ET each trading day. Consecutive days build a streak that ranks beside your draw score.
The way up · Think
A one-line why under any stance you take. After the draw, the AI Coach shows what held up and what you missed.
Six chambers · six chances
Each chamber is a market-cap band: the emerald Megawatt ball holds the $1T+ giants, Chamber 6 the $100B names. What sets the payout is how many companies sit inside a band — 33 names is a far harder call than 9, so Chamber 6 pays 33 points a match and Chamber 2 pays 9.
Match bonuses
Every ball you match pays its own chamber points, one at a time. Match two or more in the same week and a bonus lands on top of those points — and it climbs steeply, so a handful of right calls is worth far more than the sum of its parts.
A single match pays chamber points only — the bonus table is what turns a good week into a big one.
The bonus ladder
on top of chamber points
Match all six and the week is yours: chamber points from every ball plus the 10,000 bonus.

Held up: guidance was the swing factor, as you said.
Missed: supply limits could cap orders. Name a number next time.
