They made themselves comfortable in the room.
"You have a chance to take part in three sports. Free-fall wrestling, mercuryball and space chess." Dixon glanced at Houseman and Withrop. "From the looks of Cadet Astro, free-fall wrestling should be child's play for him!"
Astro merely grinned.
"Mercuryball is pretty much like the old game of soccer," explained Houseman. "But inside the ball is a smaller ball filled with mercury, making it take crazy dips and turns. You have to be pretty fast even to touch it."
"Sounds like you have to be a little Mercurian yourself," smiled Tom.
"You do," replied Dixon. "Oh, yes, you three play as a unit. Competition starts in a few days. So if you've never played before, you might go down to the gym and start practicing."
"You mentioned space chess," asked Roger. "What's that?"
"It's really nothing more than maneuvers. Space maneuvers," said Dixon. "A glass case, a seven-foot cube, is divided by light shafts into smaller cubes of equal shape and size. Each man has a complete space squadron. Three model rocket cruisers, six destroyers and ten scouts. The ships are filled with gas to make them float, and your power is derived from magnetic force. The problem is to get a combination of cruisers and destroyers and scouts into a space section where it could knock out your opponent's ships."
"You mean," interrupted Astro, "you've got to keep track of all those ships at once?"
"Don't worry, Astro," commented Roger quickly. "You use your muscles to win for dear old 42-D in free-fall wrestling. Corbett here can pound down the grassy field for a goal in mercuryball, and I'll do the brainwork of space chess."
