Board Game Arena

BGA says that this can be 1-4 players. I've never played any 1 player games before on BGA, but wanted to try Bandido as a 1 player. Anyone know how? It told me that I had to invite friends to play.

We just played for the first time two days ago. I've never played IRL before. It looked like we were able to play a card next to two cards (to make a loop). An undo or confirm would be useful.
