I gamble solo because I don't want to have doubts on what I decide because there are other players that contributes to decision. I play solo since I prefer it and I'm at peace when I have the control for every decision, it's easy, peaceful and the profit is only yours.

If I lose then there's no one to be blamed on the outcome, the weight is on your shoulders so it's preferable to gambling solo. But if it's really for fun like losing money is not a big deal then it's fun, having a good bonding through gambling and laugh all of your losses, to avoid stress because it's just an entertainment.
