I've played 5 at a time,but try to stick to no more than 3...When playing more than a couple though you don't have time to observe the other players at your tables...At most you only have time to click!!...And just a warning,with more than one table open...be very careful about them overlapping and popping up unexpectedly because it is VERY easy to call an all-in or raise when you didnt mean to...The tables pop up quick
