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”.

I don't think there's any sports I won't watch that I had a bet on. In football, sometimes I can't watch every games as different games in different leagues and same leagues are being played at the same time. I enjoy football and it's the game I bet most on. My second highest bets are in Tennis and I love watching tennis. I might skip a few moments if its getting too long. My third most bet games might be cricket and with so much T20, it's never boring. I do skip most time in Test cricket and some in ODI. The fourth one is probably NBA, and it's a fast paced sport worth watching.
