Review, by The Rabbit: "While it's a fun distraction in small bursts and certainly does few things intrinsically wrong, Sonic Rivals is not going to be the next best thing." [Score: 6.5 out of 10] <small>(January 28, 2007)</small>

Review, by Rob Fahey: "...Sonic Rivals still stands head and shoulders over other recent efforts in the franchise - and, indeed, over many other recent PSP titles - simply because the game at the heart of it all is downright fun." [Score: 7 out of 10] <small>(January 11, 2007)</small>

Review, by Paul Devlin: "while nothing groundbreaking or revolutionary, this is a very polished and thoroughly enjoyable game that proves, along with last year's Sonic Rush on DS, that Sonic is far more suited to handheld consoles than he is their bigger brothers."
