About this game
Sonic Speed Run is a retro-style pixel endless runner where you take control of Sonic as he sprints forward without pause. Your job is to collect rings, avoid hazards, and keep your run alive for as long as possible. Each attempt pushes the pace a little faster, so timing and quick reactions matter more with every second.
You decide how much risk to take. Playing it safe keeps you alive, but chasing extra rings means threading tight gaps and committing to jumps at the right moment. The game rewards focus, and a single mistake can end a promising run.
With its simple controls and nostalgic look, this browser game is easy to pick up and hard to put down. It is a great pick for chasing personal bests or trading high scores with friends.
How to play
Press Spacebar to jump. Press Spacebar again while in the air to double jump. Collect rings and avoid hazards to keep your score climbing.
