How La Primitiva works
A line is 6 numbers from 1 to 49, plus 1 Complementario from the same machine, plus 1 Reintegro from a separate 0–9 draw. To win the jackpot you need every one of them, which happens about 1 in 139,838,160 for a single entry. That figure comes from the matrix itself — the number of ways 6 balls can be chosen from 49 — and not from anywhere else.
Nothing about a previous draw changes the next one. The balls have no memory, the machine is checked before every draw, and a number that has not appeared for a year is exactly as likely as one that came up on Saturday.
