"Lego Racers" gameplay received a mixed reaction from critics. Charla called creating and testing cars a lot of fun, especially because the way a car is built has "a major effect on how it controls", and Ward found that unlocking new bricks in the circuit mode for use in car customization is addictive. However, Stahl called the game's construction system unfriendly, stating that the player is "better off just sticking with one of the default vehicles". Imperio said that handling the cars is "surprisingly tight", calling the N64 control scheme intuitive. Conversely, Charla found that most of the cars feel top-heavy, and stated that the racing is awful. Ward praised the power up system, calling it pretty cool, as well as stating that the Power Plus bricks add "a new strategy to the game", but Stahl called the system "terribly lame". Reviewers also criticised the game's multiplayer features, with Ward calling the split screen mode simple, and Crispin Boyer of "Electronic Gaming Monthly" stating that the "lack of multiplayer options" hurts "Lego Racers" replay value.
