Mega-Sena system entries — what they really buy

A System N entry plays every 6-number combination of your N chosen numbers. That is C(N, 6) standard games in one — the odds improve by exactly that factor, and so does the price.

The honest read: per dollar, a system entry gives exactly the same jackpot odds as buying the equivalent number of standard games. What changes is the prize pattern: when several of your numbers come up, overlapping combinations win in multiple divisions at once — bigger clustered wins, more draws with nothing. See System 8 vs 28 standard games and the system cost calculator.
