well, that's because it is on the safer side of gambling without losing anything,
And if you don't take anything, it isn't called gambling. I would also love to win in gambling without losing anything but obviously gambling platform is created as a business so one way or another, the platform will win if we keep on playing in the long run.
but i prefer to call that as just a game for free since you didn't have to risk that much so winning or losing doesn't matter too much and on the brighter side, if ever you won then you will still earn.
I greatly agree, I had been saying that a game isn't gambling if there is no stake from the player.
it's not that we have different perspective on different aspects of this world, but for me every decision you've made are always carrying risk, even if we say that you are playing it safe at the end of the spectrum. i understand that the consequences of losing this time isn't that much heavy compared to when you are actually putting in some amount but a risk is still a risk that's why i just prefer to call it a game than gamble.
I think it is dependent on the situation if risk is present or not. In this case, there is a free participation and a possible reward. There is no risk involved here so I agree, that the situation given by @OP is only a game, not a gambling.
