i play lotteries on really rare occasions but unfortunately i never win anything on them because it is really hard to do that
That is true. Very difficult to do any calculations to find out the winning number in lottery so it completely depends on only pure luck. I also bought few times so for but so for no luck for me as well so I stopped to buying these lotteries.
There is no need to make some calculation on lottery just spend your money no more than the prize the rest is really depends on your luck. If you just want to play but depends on your luck better dont buy it because if you only buy 1 ticket it will be the same as losing
