Editor's Notes

A ninja sprints automatically across a dark rooftop skyline that scrolls faster and faster, and your only job is to read each obstacle in time

What players will love

The double-jump buys you a second chance to clear a tall block you mistimed
The slash window is brief, so trigger it just before you reach a breakable crate, not early
Sliding lowers your profile to pass under the high bars; tap-jumping into one is an instant crash
Speed never drops, so settle into a rhythm early while the pace is still forgiving

About Ninja Runner X

A ninja sprints automatically across a dark rooftop skyline that scrolls faster and faster, and your only job is to read each obstacle in time. Tall blocks must be jumped, low bars must be slid under, and small breakable crates can be sliced clean through with a quick blade swipe. One mistimed move ends the run instantly, and since speed only ramps upward, the further you go the tighter your reactions have to be. Your score is simply the distance you cover.

How to Play Ninja Runner X

The ninja runs by itself and the world scrolls past, accelerating from a slow jog up to a hard cap as you progress. Jump over solid blocks with Space (tap again mid-air for a double-jump), hold Down to slide under the high bars, and press X to trigger a short slash that destroys breakable crates in your path. Anything you fail to clear ends the run on contact, so the goal is simply to last as long as possible; your score is the distance traveled.

Controls

Space or Up to jump (press again in the air to double-jump). Down to slide. X to slash. On mobile, tap the top of the screen to jump, hold the bottom to slide, tap the right side to slash. P to pause.

Frequently Asked Questions

Is there an end to the game?

No, it is an endless runner. The pace keeps climbing toward a top speed and the goal is the highest distance score before you hit something.

What does the slash do?

A slash opens a brief cutting window that destroys the breakable crate obstacles in your lane. Those crates are the only thing it affects; everything else must be jumped or slid under.
