Adjust your orbit radius and slip through gaps without touching the barriers.
Your point moves around automatically. Drag inward or outward relative to the center, or hold Up or W to move outward, or hold Down or S to move inward. Avoid barriers.
Your point orbits the center automatically. Move only its orbit radius inward or outward to slip through the open radial corridor in each incoming gate. Survive as long as you can without touching a barrier.
Mobile: drag inward or outward relative to the center. Desktop: drag with the mouse, or hold Up/W to move outward and Down/S to move inward.
You earn 1 point for every 0.1 seconds survived and 50 points for every gate you clear. A single barrier hit ends the run.
Your point continues around the center while you adjust only its radius. Gates approach during that adjustment, and radial movement is limited to 0.7 radius units per second within the 0.28–0.82 range. Read the opening before it arrives; a late reversal may not cover the distance in time.
The score is one point per full 100 ms survived plus 50 for each cleared gate. For example, 1,000 ms alive and one gate cleared gives floor(1,000 ÷ 100) + 50 = 60 points.
Orbit Slip separates continuous angular motion from your radial input. You read a moving gate’s safe radial corridor and move inward or outward while the point keeps orbiting, rather than steering around the board with a free-direction control.
