Do you have a sports that you keep betting on even though you don’t watch this sports live or you don’t know the full specifications of this game?
In my case, I keep betting on tennis whenever I have spare money on my casino balance from my VIP rewards(Rakeback) after my long game session on live games. I’m not really a fan of sports betting in general but I do place bet randomly on tennis especially the Asian Handicap on live match. I’m always betting on the underdog that already has 1 set advantage to the favorite players. I do this bet just for fun no string attached.
I believe this is the literal definition of “gamble what you can afford to lose”.

Valorant and League of Legends.
I stopped playing and watching the pro-scene a few years back, especially for league, as I found the games boring and systemic, once again especially for league. Two teams pit it out in the arena trying to win the game, one team makes a blunder, the other capitalizes on it and takes the win, it's so systemic and it killed the hype for me. However, I still gamble in some matches for these games especially if I'm acquainted with the teams that are at play, as I believe that allows me to maximize my win cons and actually earn something in the process. With these games that are updating on a whole monthly basis just missing out on a season or two's gonna make you feel like you're playing/watching a different game, which is also partly the reason why I don't watch the games anymore even when I place bets on them cause I couldn't for the life of me figure out the inner workings of every match anymore.
