Joker Poker, and the only game I ever set to 5 ball, because the rules are so good. Definitely a desert island pin/one more game pin.
The 5 bank of Aces is so tough, that if you end up getting the far left one, it's abandon all others and focus on the Aces for light extra ball. It's one of those games where you can get caught being greedy, like "oh...I'll pick off that ten soon for the 5x bonus, but I wanna hit those three queens right quick...doh!" Drain. Getting all drop down in one ball feels great, and with them resetting, there's always something to shoot. Best game out there from that era in my opinion.
Countdown is no slouch either.
