WORLD'S FINEST COMICS 185 (June 1969)--1st story, "The Galactic Gamblers" by Kanigher, Andru and Esposito:
The Galactic Gamblers of Garenvol teleport the World's Finest Team to their Planet of Chance under a red sun. Rival competitors, Rika and Zada, bet on Superman and Batman as they are put through a series of contests.
To up the stakes, the Galactic Gamblers have taken Jimmy Olsen and Robin hostage, as the Action Ace and the Detective Dean enter the Maze of Malice.
In the end, Clark has been playing possum. The red sun was a red herring--it was actually yellow all the time--it only appeared red to the Galactic Gamblers because of an optical illusion. Victory was not in the cards for the Galactic Gamblers.
