The Croc games were subject to various contests to help promote the games.

Back in late 1997, Argonaut sponsored a mail in contest, held by Ziff-Davis Inc. to help promote the first Croc game.  The contest pictured to the right was featured in Ziff-Davis gaming magazines like Electronic Gaming Monthly in late 1997. To enter the contest, you had to mail in a postcard with your name, address, & phone number to their sweepstakes department.

The prizes included: 1 Grand Prize received a suede wool-embroidered limited-edition jacket, 1 leather Croc backpack, 1 Croc: Legend of the Gobbos game, 1 Croc T-shirt, and 1 Croc hat. Croc Wikia user Croc Dundee won the grand prize. 5 First Prize winners received 1 Croc: Legend of the Gobbos game on the console of their choice, either PlayStation or Saturn and 1 leather Croc backpack. 15 Second Prize winners received 1 Croc T-shirt and 1 Croc hat.

Winners were decided by a random drawing held on December 1st, 1997. Winners were notified by mail and telephone.

Another contest included the prize of a family trip to Australia plus a life size Croc plush.

Another contest held in the UK was searching for the biggest Croc fan. The winner won a tour around the Argonaut studios.
