About Ninja Runner
Run continuously, jump or slide past incoming obstacles, and survive long enough to raise your score. Running speed starts at 4 and increases by 0.3 each time the internal score reaches another 100 points.
Low and high obstacles require different responses: jump over low blocks and slide under high ones. A slide lasts 30 update frames, while a jump starts with vertical velocity -11 under gravity 0.6.
How to Play Ninja Runner
1Start the run with a tap or movement key.
2Press Space or Up, or swipe upward, to jump over low obstacles.
3Press Down or swipe downward to slide under high obstacles.
4Keep alternating jump and slide timing as the runner accelerates.
Ninja Runner Rules
- Touching an obstacle ends the current run.
- The displayed score is the internal frame score divided by ten and rounded down.
- Obstacle spawning becomes more frequent as speed rises.
Ninja Runner Scoring
| Action | Points | How it works |
|---|---|---|
| Survival progress | floor(internal score / 10) | The internal score rises continuously while the run is alive. |
