Newbies should start with the easiest and I agree that nothing more could be easier than roulette and Dice game, but it's also addictive this is one of the issue that newbies should watch out when they are starting out, it's easy and safe in some way but beware of addiction.
Thats right, addiction would be a problem if a gambler cant control himself when playing since the game is addicting especially if you happen to be lucky and often win.
Well there's no safe gambling games, all these games has risk to lose your money whether you are a newbie or not.
Dice is the easiest for me, there's no need for deep knowledge or experience about the game because you can easily understand the flow on how to play it.
