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?" "Anywhere from three minutes to fifteen, with the average run of players. Oh, by the way, one more thing. That lead block up there—" The man motioned with his head toward a one-foot cube suspended by a thick cable. "It's rigged to drop every now and again. Averages five minutes. A warning light flashes first. You can take a chance; sometimes the light's a bluff. You can set the clock back on it by dropping another chip—or you can let go the grip." Retief looked at the massive block of metal. "That would mess up a man's dealing hand, wouldn't it?" "The last two jokers who were too cheap to feed the machine had to have 'em off. Their arms, I mean. That lead's heavy stuff." "I don't suppose your machine has a habit of getting stuck, like Kippy's?" The broad-shouldered man frowned. "You're a stranger," he said, "You don't know any better." "It's a fair game, Mister," someone called. "Where do I buy the chips?" The man smiled. "I'll fix you up. How many?" "One." "A big spender, eh?" The man snickered, but handed over a large plastic chip. IV
