I hardly ever play the lotto (as it's called in UK).
However, if on one of them.random times, I did win a big load, I'd buy a house, well bungalow (ranch style for Americans).
I'd pay off the mortgage for my step daughter and upgrade their car (it's a nice lil banger at the.mo).
Give a fat chq to my bestest friend n nephew, along with a couple friends of the fiancée.
Then enjoy the rest of it.
