| Gary Whitta reviewed Domark's conversion for The One in April 1990 at £19.99, out now. The main ratings box, which doesn't name a version and is followed by separate Atari ST and PC boxes without ratings, gives 78% for graphics, 85% for sound, 79% for playability, 78% for value, and 79% overall. He praised the plays as strategically competent and the sound, with a female commentator announcing each play's result, but found the robots sluggish at times and regretted that two people can only play as a team against the computer, not against each other. Side notes found the Atari ST version as rewarding with weaker sound, and the PC version (£24.99) supporting VGA, EGA, CGA, Tandy and Hercules graphics but no sound boards. | p. 49 (image 49), review introductionp. 50 (image 50), verdictp. 50 (image 50), verdictp. 50 (image 50), verdictp. 50 (image 50), verdictp. 50 (image 50), verdictp. 50 (image 50), ratings boxp. 50 (image 50), side notep. 50 (image 50), side note | Magazine |
| The computer versions reached the shops under Ocean in spring 1990, months after their reviews. Zzap!64 wrote in May 1990 that Ocean had finally got the Commodore 64 and Amiga conversions into the shops over six months after it first reviewed them, recalled their marks of 92% each, and suggested a Gold Medal might have been deserved. Amiga Format's May 1990 review said the conversion had "finally arrived on the Ocean label", and The One wrote in April 1990 that the game, first revealed in its pages over a year before and reviewed six months later, had only now been released. | p. 57, Players Guide (image 57)p. 57 (image 57) | Magazine |
| Graftgold's players' guide in The One (April 1990) explains that the player negotiates seven Rainbow Islands, each split into four vertically scrolling rounds. The player starts at the bottom of a round and aims for the Goal Line at the top, and must defeat the enemy within on reaching the seventh island. The heroes, Bubby and Bobby, start with three lives each. Only 12 rainbows may be on screen at once. | p. 57, Players Guide (image 57)p. 57 (image 57)p. 57 (image 57)p. 57 (image 57)p. 57, section "Bubby and Bobby" (image 57)p. 57 (image 57)p. 59 (image 59) | Magazine |
