My understanding is, if I'm not mistaken and as far as I know there is no type of game in the gambling industry that does not have risks, all types of games have risks, However, the risks faced are at different levels, there are high, medium and low risks depending on the type of game being played.

My experience in online gambling betting and the types of games that have a low level of risk and the ones I have played are: CRASH and PLINKO. For me, these two types of games, in my opinion, have a low risk of losing, Likewise, the nominal bet we want to place can be set as low as $0.1, both games are the same and we can also set the largest bet in one round, Likewise, the opportunity to win is as likely as the ball falling into the column in the PLINKO game and so on.
