He had the choice of rows or columns. He chose the rows. She would figure him to take the middle row, because two of his choices were there, so she should choose the center col umn, to stick him with Sand Dunes. Therefore he chose the top row.
But she, for what reason he might never understand, had selected the third column. The result was Glass Mountain: one of her choices, but really not bad for him. They adjourned to the mountain. As true mountains went, this was small, but as inner-dome artifacts went, it was big. The mountain was indeed formed of glass, or at least had a glass exterior. It was broad at the base, and slanted up to a peak about ten meters high. It was ridged and channeled, with many facets and some almost vertical cliffs which rep resented impassable barriers to naked—i.e., bare-handed—folk. Its contours were changed for each game, so that there was no point in memorizing its outline. It was normally so constructed that a person could not simply pick a gentle slope and mount to the top; he had to ascertain, usually by trial and error, which route was feasible, and do it before his opponent did. The first one to the top was the winner. This was “separate”; that meant that one player could not directly interfere with the other, such as by shoving him off the mountain. But the categories were seldom pristine; there was inevitably some interaction, as when one player got to the best route before the other and so forced the other either to follow behind or to choose another route. In this case there was an added fillip: water bombs. These were little balloons filled with water which, when burst against the glass, made it too slippery for progress. A player could take as many bombs as he could hold, and use them to reduce the friction of the path his opponent had chosen. The effect lasted only a few seconds, but could make the difference when both were racing toward the top on different paths. Troubot feared that his wheels would be more susceptible to slipperiness than Tsetse’s feet, because she could step over wet spots while he could not. But he had greater capacity to hold water bombs. He could fill his hopper with them, while she could carry only what she could hold in her arms. Still, he did not know how agile she was, or what the best route was. This was still anybody’s game. The audience evidently thought so; the monitor lights indicated a massive viewing, which could not be accounted for solely by the importance of the contest.
Of course. Tsetse was a lovely young woman. That would account for a significant enhancement of the number of view ers. She would be bending over to scramble up tricky slants, and perhaps taking spread-legged tumbles. That sort of thing was always big with the serfs. They would be rooting for her, to win or tumble or both, but their reactions did not matter, because they would not be audible here. They started. Tsetse ran to the mountain and clambered nimbly enough up the first channel that offered. Troubot went instead to the bomb dispensary and carefully set a dozen into his hopper. This might raise his center of gravity and make his climb more difficult, but the bombs should be more of an asset than a liability.
Tsetse’s channel faded out, leaving her on a flat facet whose tilt was more to the vertical. She climbed this carefully, her toes just beginning to skid. She was about four meters up. Troubot waited below, watching carefully, analyzing the slope she navigated; it did not matter who tested it, for this pur pose.
Then, just as she was about to reach the top of the facet so that she could step onto a more promising new channel above, Troubot flexed a metal arm and lofted a water bomb. His aim was good, of course; the bomb landed just above her, and the water coursed down across her feet. Friction diminished abruptly. She screamed as she lost her footing and slid down to the base of the mountain, in exactly the fashion the audi ence had hoped for.
Troubot did not wait to watch; he was not a living human male and would have had no gratification from the sight. He had merely taken the opportunity to test the efficacy of the 3 water so that he could estimate the coefficient of friction be fore and after. He believed she was on the wrong path, but wasn’t sure, so this would set her back while he tried an alternate route himself.
He found a facet that started steep, but curved to diminish the angle above. He started up this one, his wheels barely holding at the base. Yes, this seemed more promising; above the facet was a channel that curved upward around the moun tain. He rolled up this.
Splat! A water bomb struck his body. It burst, and the water cascaded down around his wheels. Traction was gone; he slipped helplessly, and in a moment was at the bottom. The mountain had a soft curtain or buffer at the base, to absorb the shock of landings, so that players would not be hurt by their involuntary slides. But he had lost his progress. Tsetse had retaliated.
