The mobile debut of Redlynx's vehicular platformer has been downloaded six million times since release, says Ubisoft.
Trials Frontier is free-to-play and was released on the App Store on April 10. Ubisoft says it currently tops the free app charts in 75 countries.
"We are thrilled with the success Trials Frontier has had in its first week of launch," said Jean-Michel Detoc, managing director of Ubisoft Mobile.
"Trials Frontier has the most first week downloads of any Ubisoft mobile title to date, and the thousands of players reviews we received are amazingly positive, an achievement Redlynx and Ubisoft are proud to announce. In order to keep players engaged, we have a robust post-launch content plan including new bikes and multiplayer modes that will allow players to continue exploring and enjoying the world of Trials Frontier."
Trials Frontier also connects with the recently released Trials Fusion for PC and consoles, allowing players of both games to access extra items.
