The record was at 99, well! now is very high, one player win with only 2 tickets.
In that same sense we have that the maximum number of tickets with which someone has won is now 105,991 and the most curious thing that by the same user Tybel.
Who by the way also won last time, so the two premises are demonstrated; anyone with 2 tickets can win, but also the one who has a huge amount of tickets increases its chances.
Tybel managed to do it twice the first* time with 187,282 tickets and this time with 105,991 tickets.
