Which on is crypto game?
I see all games to bring winning, the chance in the casino games are proportional to their odd. The higher the chance the lower the odd while the lower the chance the higher the odd. It is left for you which one that you prefer.
If it is sport, you have lower odds. Casinos are better I am posting about casinos alone just as it is in your question.
I also would say it depends on the odds and the risk taken in terms of how much used to stake on it. Like you said in sports games, so in lower odds games, the gambler goes on to place a higher stake on it if he feels the game will turn out to favour him And so if a game that doesn't have the winning advantage, the gambler doesn't risk much on it Therefore, it depends on some factors like the odds and how much stake placed on the bet.
Since the total amount of winning is equal in proportion to the amount of odds accumulated and the amount used to stake the bet, if your luck is on the high side football betting seems to give such possible rewards in most cases since it games can easily be analyzed and sometime book marker tries to play smart one by giving out obvious odds that could give any smart bettor a chance to get lucky and win big depending on the level of risk the gambler can take.
But I have seen someone who won almost 21 million in my local currency before but he used close to two hundred thousand of my country's currency to stake the bet, so the bigger the risk the bigger the rewards and the losses also, it all depends.
