But my boss is playing regularly and he spend 150 - 300 euros per week!!! But i understand him.. He won two times - first 150k euros and second 100k euros.. I think he play Euromillions..
You're boss reminds me one of my father's friends. He won once the 1st prize in the National Lotto. After that, he has been playing for years without any further luck. Fortunately for him, he did some good investments with the money of the prize and now he has a modest living.
The main attraction of lottery is that you there is very large sum of jackpot. So if you win, you win big. That could be the reason there are so many people play lottery. They all want to be rich overnight. In Euro millions lottery, when the accumulated prize is over hundreds million euros, there are even more people play it.
