Trials HD is an Xbox Live Arcade game developed by RedLynx and published by Microsoft Game Studios. It was released on August 12, 2009 as part of the second annual Xbox Live Summer of Arcade and was later re-released in a retail pack alongside Limbo and 'Splosion Man in April 2011. It is a 2.5D puzzle/racing game. The player must guide a trial motorcycle with exaggerated physics through various obstacles to reach each stage's finish line. On September 6, 2012 it was announced that a Microsoft Windows version of Trials HD would be bundled inside a special version of Trials Evolution, dubbed Trials Evolution: Gold Edition—although this version changes the physics of the game. It is the third game in the series. On February 11, 2016, Microsoft added Trials HD as part of its backwards compatibility program for Xbox One.

Xbox Live Arcade (XBLA) is a video game digital distribution service available through the Xbox Games Store, Microsoft's digital sales platform for the Xbox 360. It focused on smaller downloadable games from both major publishers and independent game developers. Titles ranged from classic console and arcade video games, to new games designed from the ground up for the service. Games available through the XBLA service ranged from $5–20 in price, and as of October 2016, there have been 719 Xbox Live Arcade titles released for the Xbox 360. Prior to the Xbox 360, "Xbox Live Arcade" was the name for an online distribution network on the original Xbox, which was replaced by the Xbox Live Marketplace.
