Dark Spirit Run is a free online endless runner game where you control a lone ninja sprinting through a cursed, shadow-filled world packed with deadly obstacles. Every second counts as you race through an infinite night, dodging flaming hazards, spinning metal blades, and ghostly spirits that appear without warning. Your only job is to survive as long as possible — and that gets harder fast. The controls are simple, but mastering the timing is anything but. Flaming traps demand quick hops, spinning blades require split-second slides or jumps, and ghost spirits test your pattern recognition under pressure. The dark visual style keeps you focused on what matters — the next obstacle. There's no hand-holding here. You learn by failing, then you push further each run, which makes every new personal best feel genuinely earned. Dark Spirit Run is a perfect pick for fans of casual clicker-style reflex games, ghost-themed runner games, and anyone who enjoys short, intense sessions with high replay value. If you like ninja games, endless survival games, or spooky arcade runners, this one fits right in. Search terms like free ninja runner game online, ghost obstacle course game, and endless runner no download all lead here — and for good reason. No login, no install, just run.
