So lottery, slot games are all possible ways to lose your money but about addictive probability and risk, I think slot games are more addictive than lotteries. You can lose money with slot games faster than with lotteries because with slot games, it's very continuously while lotteries are not and have cooling down time for you.
The difference is too much when it comes to addictiveness. Slots games can get you addicted faster because of the availability to play it always while lotteries are seasonal. If you try out the lottery and you don't win the time space for you to cool and try again is long and limits your losing spree and possibility of being addicted but with slots you can continually empty your bank role since there are lots of time and games to try.
