The broad-shouldered man lit a perfumed dope stick. "What would you call big?" he said softly.

"What's the biggest you've got?"

The man narrowed his eyes, smiling. "Maybe you'd like to try Slam."

"Tell me about it."

"Over here." The crowd opened up, made a path. Retief and Magnan followed across the room to a brightly-lit glass-walled box.

There was an arm-sized opening at waist height. Inside was a hand grip. A two-foot plastic globe a quarter full of chips hung in the center. Apparatus was mounted at the top of the box.

"Slam pays good odds," the man said. "You can go as high as you like. Chips cost you a hundred credits. You start it up by dropping a chip in here." He indicated a slot.

"You take the hand grip. When you squeeze, it unlocks. The globe starts to turn. You can see, it's full of chips. There's a hole at the top. As long as you hold the grip, the bowl turns. The harder you squeeze, the faster it turns. Eventually it'll turn over to where the hole is down, and chips fall out.

"On the other hand, there's contact plates spotted around the bowl. When one of 'em lines up with a live contact, you get quite a little jolt—guaranteed nonlethal. All you've got to do is hold on long enough, and you'll get the payoff."

"How often does this random pattern put the hole down?"
