Rainbow Pen

Draw a Continuous Line
Use your mouse or touch controls to draw a continuous path. The pen moves along the drawn trail, spreading paint behind it.

Collect Color Points
Your path should pass through all paint stations or color nodes. These refill your pen and allow you to paint through multi-colored segments.

Avoid Collisions and Overlaps
Paths cannot cross themselves or overlap walls. Planning efficient non-intersecting routes helps avoid mistakes.

Fill All Target Zones
The goal is to cover all designated areas or tiles with paint. Complete coverage without leaving gaps reveals the exit point.

Use Minimal Path Length
Some levels reward shorter, clever lines. Try to draw efficiently to save strokes and maximize score.

Advance Through Pattern Complexity
As levels progress, maps become more intricate—showing multiple colors, barriers, and tighter spaces requiring sharper planning.
