''Tux Racer'' is a racing game in which the player must control [[Tux (mascot)|Tux]] across a mountainside. Tux can turn left, right, brake, jump, and paddle, and flap his wings. If the player presses the brakes and turn buttons, Tux will perform a tight turn. Pressing the paddling buttons on the ground gives Tux some additional speed. The paddling stops giving speed and in turn slows Tux down when the speedometer turns yellow. Tux can slide off slopes or charge his jumps to temporarily launch into midair, during which he can flap his flippers to fly farther and adjust his direction left or right. The player can also reset the penguin should he be stuck in any part of the course.<ref name=tr-manual>{{cite web|url=http://tuxracer.sourceforge.net/manual.html|title=Manual|website=[[SourceForge]]|publisher=Sunspire Studios|access-date=July 4, 2019|archive-date=May 27, 2018|archive-url=https://web.archive.org/web/20180527134703/http://tuxracer.sourceforge.net/manual.html|url-status=live}}</ref>

Courses are composed of various terrain types that affect Tux's performance. Sliding on ice allows speeding at the expense of traction, and snow allows for more maneuverability. However, rocky patches slow him down,<ref name=rl-5th>{{cite book|title=Running Linux|last1=Dalheimer|first1=Matthias Kalle|last2=Welsh|first2=Matt|publisher=[[O'Reilly Media]]|edition=5th|pages=190–193}}</ref>{{rp|193}} as does crashing into trees.<ref name=idg-review/> The player gains points by collecting herrings scattered along the courses, and the faster the player finishes the course, the higher the score. Players can select cups, where progression is by completing a series of courses in order by satisfying up to three requirements: collecting sufficient herring, finishing the course below a specified time, and scoring enough points. Failing to meet all the criteria or aborting the race costs a life, and should the player lose all four lives, they must reenter the cup and start over.  During level selection, the player can choose daytime settings and weather conditions such as wind and fog that affect the gameplay.<ref name=tr-manual/> Maps are composed of three separately saved [[Raster graphics|raster]] layers that each determine a map's elevation, terrain layout,<ref name=idg-review/> and object placement.<ref name=tr-faq>{{cite web|url=http://tuxracer.sourceforge.net/faq.html|title=Tux Racer FAQ|website=[[SourceForge]]|publisher=Sunspire Studios|access-date=July 4, 2019|archive-date=June 2, 2018|archive-url=https://web.archive.org/web/20180602002524/http://tuxracer.sourceforge.net/faq.html|url-status=live}}</ref>
