It was the same here. The pilot board at the croupier's rostrum had a prearranged mathematical pattern on it. The idea of the game was to set up your own board in the identical pattern. As each succeeding coordinate on the graph was called out, you recomputed in terms of the new probabilities, rubbing out old equations and substituting new ones.
There was always the mathematical chance that a pattern set up at random would be identical to the master control pattern—but that was a pretty slim chance. It took brains to win at this game. The man whose board was first to match the pilot pattern won.
Hawkes worked quietly, efficiently, and lost the first four rounds. Alan commiserated. But the gambler snapped, "Don't waste your pity. I'm still experimenting. As soon as I've figured out the way the numbers are running tonight, I'll start raking it in."
It sounded boastful to the starman, but Hawkes won on the fifth round, matching the hidden pattern in only six minutes. The previous four rounds had taken from nine to twelve minutes before a winner appeared. The croupier, a small, sallow-faced chap, shoved a stack of coins and a few bills at Hawkes when he went to the rostrum to claim his winnings. A low murmur rippled through the hall; Hawkes had evidently been recognized.
His take was a hundred credits. In less than an hour, he was already seventy-five credits to the good. Hawkes' sharp eyes glinted brightly; he was in his element now, and enjoying it.
The sixth round went to a bespectacled round-faced man three tables to the left, but Hawkes won a hundred credits each on the seventh and eighth rounds, then lost three in a row, then plunged for a heavy stake in his ninth round and came out ahead by five hundred credits.
So Hawkes had won four times in nine rounds, Alan thought. And there were at least a hundred people in the hall. Even assuming the gambler did not always have the sort of luck he was having now, that meant most people did not win very often, and some did not win at all.
As the evening went along, Hawkes made it look simple. At one point he won four rounds in a row; then he dropped off for a while, but came back for another big pot half an hour later. Alan estimated Hawkes' night's work had been worth more than a thousand credits so far.
The gambler pushed his winnings to fourteen hundred credits, while Alan watched; the fine points of the game became more comprehensible to him with each passing moment, and he longed to sit down at the table himself. That was impossible, he knew; this was a Class A parlor, and a rank beginner such as himself could not play.
But then Hawkes began to lose. Three, four, five rounds in a row slipped by without a win. At one point Hawkes committed an elementary mistake in arithmetic that made Alan cry out; Hawkes turned and silenced him with a fierce bleak scowl, and Alan went red.
