And he was thinking:

I lifted the battered ship on Gygni VII and maneuvered it through space. I was the engine and the pilot, the tubes and navigator. Energy garnered by my body took the ship and lifted it and drove it through space…eleven years through space. I brought the ship tonight down through atmosphere with the engines dead so it could not be spotted and I landed in the river. I could pick a book out of that case and carry it to the table without laying hands on it and I could turn the pages without the use of fingertips.

But dice.

Dice are different.

They roll so fast and topple so.

"Win or lose," said Adams, "you can use the visor."

"If I lose," said Sutton, "I won't need it."

Jonathon came back and laid the dice upon a tabletop. He hesitated for a moment and when he saw that the two humans were waiting for him to go, he went.

Sutton nodded at the dice carelessly.

"You first," he said.
