He was asked me what is the safest crypto gambling game for them that they never encounter. Though playing cards are very common like poker, Tong-its or Blackjack, it is different when you are online.
Well if you speak about safest games don't think I can point out a particular games as the safest, as what might work for me might not work perfectly for another gambler. As a gambler I find sport related games as the most safest option, that's why my gambling experience has revolves around sport betting. When I don't place bet on sport games I go for card games, I'm somehow good at those too as if I was to grade myself I'll score a 8.5/10.
The choices you highlighted above aren't that bad and they can choose from them, practice and improve on their knowledge. What makes gambling more profitable has a lot to do with experience and obviously the luck factor so if they have both, I'm quite sure irrespective of the game they pick interest in will become somehow easier for them to related with.
