Since Sega and Hardlight released endless runner Sonic Dash on mobile platforms in 2013, the game has remained by far the most popular Sonic mobile title, netting $10.8 million in revenue since 2014.
This is according to PocketGamer.biz, sharing data obtained from mobile analytics firm Sensor Tower. According to this data, Sonic Dash has brought in more revenue than the last five Sonic mobile games combined: Sonic at the Olympic Games, Sonic Forces, Sonic Dash 2: Sonic Boom, Sonic Runners, and Sonic Jump Fever -- the latter two both now being inactive.
PocketGamer noted that this data does not include Sonic Racing, as that title is a part of Apple Arcade subscriptions.
