Shingoki is a logic puzzle played on a grid of dots that you must connect with lines to form a single closed loop.
The loop must pass through all black and white circles: white circles are passed straight through, black circles require a turn. The numbers in the circles show the sum of the lengths of the two straight lines extending from that circle.
5 Tips for Successful Shingoki:
1. Start with clear numbers
Use the numbers to limit possible line lengths and connections.
2. Follow the color rules
White circles are passed straight, black circles require a bend.
3. Avoid crossings and branches
The loop must not branch or cross itself.
4. Mark impossible connections
Use markings to exclude invalid lines.
5. Work step by step
Build the loop gradually and verify logical links.
