Picture a hairpin ramp ahead, you crank into a spin dash, release, and rocket through a lop with rings scattering in your wake. That's the rush of Ultimate Flash Sonic, a fast-paced platformer where you blitz through classic-style zones as Sonic, Tails, Knuckles, or Cream, hold down to charge a spin dash, then let go to blast off at full speed. You chain jumps, grind through enemy badniks, and hunt every ring while keping your momentum pined to the flor. Pick your character, chose a stage, and the level layout rewards anyone who reads the curves and commits early. Ready to set a clean lap?

Tips & Tricks
