I don't know if there are even gambling games which could be safe because it is gambling that we are talking about, risj therefore is present, invalidating a game being safe. But I would say sportsbetting would be the closest to such criteria especially if you are into sports. You only need to choose from teams or athletes that you think would win the game and most of the time, popularity would determine which one would be the best tk invest and gamble. But still, I won't give assurance for a 'win', again, this is a gamble, there is always a chance that you would lose.
What do you think? --can I recommend dice and roulette gambling game since among the poll I listed this is the easiest gambling I have ever known. I added a poll and lock this thread once I have got satisfied answers from our fellow gamblers on this community.
In terms of understanding the games and patterns, dice games are definitely the easiest. It's quite direct and nothing too complicated. The thing that could make it complicated is how much are you going to risk and can you control your emotions. Knowing that would be beneficial for the newbie.
In my case, i find it hard to make a 'pattern' in dice. Winning is more uncertain in such kind of games in my opinion, and this could be classified as one of those gambling games which are pure-luck-based. Strategical games would be those of card games, I think.
