It was kind of surprising how long it took Sega to make an endless runner featuring Sonic the Hedgehog on iOS. Thankfully, when Sonic Dash [Free] finally appeared a few years ago, it was actually pretty solid (as far as free-to-play behind-the-back runners go, of course). In my opinion the recently released sequel, Sonic Dash 2: Sonic Boom [Free] is even better, so we’ve decided to put together some tips and tricks to help you be the blue-iest blur this side of Green Hill Zone.
