Ports and remakes
On February 5, 2002, Sunspire Studios released in retail a closed-source and commercial expansion of the game titled Tux Racer, with each CD designed to support both Linux and Windows operating systems. Improvements from the open-source version include a vastly enhanced engine and graphics, the ability to perform tricks, character selection, and competitive multiplayer. The open-source version of Tux Racer, however, remained available to download on SourceForge.: 191  Sunspire Studios ceased business towards the end of 2004.Since its inception, Tux Racer has seen unofficial updates. One of the most popular examples is Extreme Tux Racer, released in September 2000, PlanetPenguin Racer. An arcade version of the game was released by Roxor Games, making it the first GPL-licensed video game to receive an arcade adaption.Reception
Tux Racer was well-received, with the latest version seeing over one million downloads as of October 2001 since its release in January, according to Sunspire Studios. It was a personal fan favorite among Linux users, who often ranked it as the best or one of the best free games. In August 2000, Lee Anderson of LinuxWorld.com commended the game's graphics, speed, and the easiness of the ability to create tracks. In 2001, TuxRadar said the game provided a "shining light" of what free applications could achieve. In its 2001 preview, the Brazilian magazine SuperGamePower considered the game's graphics to be the best aspect and described the sound as not innovative, but good. Also in 2001, MacAddict compared the game's fast-paced style to podracing in Star Wars and summed up the Macintosh port as "more fun than words can describe."The commercial version of Tux Racer attracted little attention. Andon Logvinov of Igromania described it as a "pure arcade game" featuring nothing but four selectable characters and a set of courses with fish scattered about. He described the gameplay as calm and addictive and the music as relaxing, and praised the character models and track layout, with his only criticism being the system requirements.  Seiji Nakamura of the Japanese website Game Watch described it as cute and humorous and praised the game's graphics and shadow and reflection effects, but found the game to lack appeal for adults.Even after its production's cessation, Tux Racer has continued to be generally well-received. Linux Journal gave it an Editors' Choice Award in the "Game or Entertainment Software" category in 2005. Digit applauded the graphics and replayability, as well as the speed of the game and the abundance of courses, but found the music to be monotonous. Daniel Voicu of Softpedia praised the Extreme Tux Racer for being relaxing and funny and having the ability to reset Tux, as well as noted the game's fast pace, but criticized its perceived lack of interactivity and having Tux look like a "plastic puppet." Linux For You called it entertaining but also criticized its bugs and the "plastic" look of Tux.
