How to Play Shingoki
Draw a single closed loop visiting all circles. Numbers on circles indicate how many times the loop turns at that circle.
Try it now — Easy 7x7 →The Rules
- Draw a single closed loop that visits every circle
- At black circles the loop must turn (90°)
- At white circles the loop must go straight through
- The loop cannot cross itself
Available in 3 sizes (5x5, 7x7, 10x10) and 3 difficulty levels (easy, normal, hard).
See It in Action
Draw a single loop that visits every circle — black circles force a turn, white circles force straight
How to Play
- Identify all black circles — the loop turns here; determine which two of the four possible directions apply
- Identify all white circles — the loop goes straight here; determine the axis (horizontal or vertical)
- Extend forced segments outward from determined circles
- Complete the loop ensuring it visits every circle without crossing itself
Pro Tips
Black circles in corners force a specific turn because only one 90° shape fits a corner
Straight segments at white circles often create long forced runs through the grid
Follow the loop continuously — once you can trace from one forced segment to the next without branching, those cells are set
Frequently Asked Questions
What is Shingoki?
Shingoki is a loop puzzle. Draw one closed loop visiting every circle. Black circles mean the loop turns there; white circles mean the loop goes straight. Numbers on circles indicate the total loop length passing through in some variants.
