On IGN, it received a 3 out of 10, reviewer Craig Harris stating ""Cartoon Network Speedway" is one of the sloppiest and most generic kart racers released on the Game Boy Advance." It currently has a 53% rating on GameRankings. It was also given a 65 out of 100 from Next Level Gaming, a 3 out of 5 from "Nintendo Power", and 58 out of 100 from "VG-Force".
