| Mark Caswell reviewed Cyberball for The Games Machine in May 1990, listing it from Tengen/Domark for the Amiga and Atari ST (£19.99 each), PC (£24.99), and Commodore 64, Spectrum and Amstrad CPC (£9.99 and £14.99). The review's only score box rates the Amiga version 87%. He described a game of six three-minute periods, found the graphics good, with menacing robots, but in-game sound limited to muffled speech and effects, and missed the quarterback's voice calling the play as in the coin-op. | p. 46 (image 46), details boxp. 46 (image 46), score boxp. 46 (image 46)p. 46 (image 46), Cyberball review, details boxp. 46 (image 46), details boxp. 46 (image 46)p. 46 (image 46)p. 46 (image 46)p. 46 (image 46), signature | Magazine |

| The Games Machine reviewed Klax in May 1990, by Mark Caswell, and gave the Atari ST version 92% with its Star Player badge. The ST comment found the controls "a little tricky to master", the graphics "very good indeed", and Klax not "instantly playable", but a game that "grows on you". | image 38, Klax reviewimage 38, Klax review, Atari ST commentimage 38, Klax review, Atari ST commentimage 38, Klax review, Atari ST commentp. 38 (image 38), Klax review, rating box, read on the page imagep. 38 (image 38), Klax review, read on the page imagep. 38 (image 38), Klax review, Atari ST comment | Magazine |
