Discrete runs of the same game can vary substantially based on self-imposed restrictions such as using a specific character, playing the game on a specific [[Game balance#Difficulty level|difficulty level]], avoiding the use of glitches and exploits, or requiring completion of optional objectives.<ref name="CompletionPercentage" /> These restrictions can result in a single game having multiple (often contradictory) definitions of completion, called [[Speedrun#Completion|categories]].<ref>{{Cite web|url=https://kb.speeddemosarchive.com/Rules#Additional_category_tags|title=Additional Category Tags – Rules – SDA Knowledge Base|website=kb.speeddemosarchive.com|access-date=2019-01-24|archive-url=https://web.archive.org/web/20190124152446/https://kb.speeddemosarchive.com/Rules#Additional_category_tags|archive-date=24 January 2019|url-status=live}}</ref> Consequently, a single game may possess separate leaderboards for each [[Speedrun#Completion|category]].
