Quoted from Mahoyvan:I find the most common problem when i have casual-player friends or family over, or even the old lady, is that my ball times are so much longer that I have to fake draining. It’s agonizing for everyone and like you said, just not fun!
Best answer for that is the JJP games with the "BALLS IN RESERVE" option. The casuals only have to wait through one _physical_ ball, and once they're done, they can move on to another machine while you finish all your EBs.
