When I was still actively playing lotto here in my country, I can remember alot of times I has to take excuse or permission from my working place to quickly go out and place a bet on some lotto numbers that was sent to me by a friend, back then, we had a network of individuals who we often referred to as insiders, they 90 percent of the time know what numbers will play because they worked closely with the lotto officials, all they usually do is, secretly pass those numbers across to us and we bet big money on them, and after we win and claim the money, we give them their cut, usually around 25 to 30 percent of the profit made.
Things like this can still come in-between a gambler and their other daily activities, most especially if the gambler is a seriously committed gambler, so, in essence, only playing gambling when totally free all depends on the type of gamble a person is, a hardcore gambler will definitely suspend everything he or she is doing to play gambling when ever an opportunity appears in the market.
At in here there are so many layers of security and transparency and changes to audit the lotteries, that it would be highly improbable someone could cheat in it. It would require so many people being in that same scam that profits for it wouldn't be worth the risk of getting caught.
Even before internet, the security was tight for the both machine and there are tv cameras watching the lottery live with a police standing next to the machine . Which was quite over the top but send a signal of integrity of the raffle. In here trust on police is quite high because of the transparency and regulatory oversight and weekly lottery with a police was similar to elections, which are considered almost holy ceremony, as we are so proud of the integrity of the whole event.
