Shingoki


Translate this site.

Shingoki (Semaphores) is a logic puzzle with simple rules and challenging solutions.

The rules are simple. You have to draw lines between the dots to form a single loop without crossings or branches. The loop should pass through all black and white circles in such a way that:
- White circles must be passed through in a straight line
- Black circles must be turned upon
- The numbers in the circles show the sum of the lengths of the 2 straight lines going out of that circle.

Left click between the dots to connect them. Right click to mark with X.
