It took Jace some time to even understand when or if it was his turn, but soon enough he got the hang of the game, even if he couldn't join in on the conversation (or insults) the others were sharing. He understood the game well enough, but decided to do a few poor moves. If these were to be his fellow passengers for the ride, and they were all armed and stronger than him, he'd rather not leave them in a sour mood. 

He played the game until the others tired of it, or until somebody started a winning streak.
