We also know the cadence of the rest of the ‘World Tour’ events, too. Popstar Amy has arrived in Sonic Forces: Speed Battle, and if you want to keep her as an active competitor you must collect a number of character tokens in order to have her on the roster. Tucked away in its community Discord channel, SEGA HARDlight revealed via its Events Calendar that the first event in the ‘World Tour’ series has begun today. And what’s more, you can start working towards unlocking one of these new players right now! Sonic Dash was developed by Sega's internal mobile studio Hardlight.After casually announcing it without much fanfare, SEGA HARDlight has shadow-dropped the dates for its newest Sonic Forces and Sonic Dash characters, Popstar Amy and Rockstar Rouge. It may be popular, but Sonic Dash is still nowhere near Angry Birds or Temple Run, both of which have exceeded 1 billion downloads to date. Sega has not provided any details, however, regarding the profitability of Sonic Dash. Being a free-to-play game, Sonic Dash relies on microtransactions to make money.

Sonic Dash is available now as a free download across iTunes, Google Play, and Windows Phone. With over 100 million downloads, Sonic Dash becomes the most downloaded Sonic game in history. For example, Sonic has run 1.1 billion miles in-game, players have collected 850 billion gold rings, and have spent a cumulative 14,000 years playing the game.

To mark the milestone, Sega has released a new infographic that covers some massive statistics about the game. Released two years ago in March 2013, Sega's endless runner Sonic Dash, based on the company's iconic series Sonic the Hedgehog, has now reached 100 million downloads.
