I wish to know if these games such as FPS which you can put for example in a room of 10 players everyone puts 5 dollars and the winner takes the whole 50 dollars, Are considered as gambling.
And also if theres any known and trusted website or casino that allows such games. I find them better than gambling and lucky games
Even conventional works when people stake money hoping to win and the winners are normally paid from the pool of looser while losers go empty. As long as people come to play a game and money is involved, its gambling. It is not gambling if each player doesn't stake money with the intention to win. An example might be if someone promises to give the winner a some of money without the contribution or bet of the players. This one can be called competition with a prize and not necessarily gambling.
This kind of games is popular in my location and it is always done manually or physically. I am not aware of any casino that offers such services.
