The last vada
Ten vadas left and a crowd reaching for them at once. How does the stall sell exactly ten - and what does each way of making sure cost?
Ten vadas sit on the tray and a rush of buyers reaches for them inside 120 milliseconds. The panels show how many vadas were promised, how long an answer took, and what each buyer went home with. Grab freely and phantoms appear; guard the count and someone pays in waiting or retries.
On a narrow screen the three panels stack. The dial and tabs stay above them, and the table scrolls sideways.
