Yesterday I played free card games on the computer and had a lot of fun and it was also quite exciting. You know, I play different games: both paid and free. And sometimes, based on the fascination and the pleasure I get, I find it difficult to say which games captivate me more. But I would be interested in how you answer the question of whether free games can be considered gambling. Another way to put this is: can gambling be free? Do free games excite you as much as games that involve betting money?
Any form of game that you are playing and you don't spend any penny in the game and you also don't expect to win anything from the game in return aside from the fun you get by participating in that game is not gambling; it's just a mere computer game that you are playing.
Gambling involves risking a particular amount of money, an asset, or anything else in exchange for the fun that you are deriving from the game, and in return, you also expect to make a little win from the game, making you either happier when you win, not just because you won the game, but because you also make some profit, or vice versa when you also lose a game.
