🎯 Objective

Draw a single continuous path that passes through every cell of the grid exactly once — visiting each numbered node in order from 1 to N.

🕹 How to Play

• Click node 1 to begin your path.
• Click or drag through adjacent cells (up, down, left, right — no diagonals).
• You must reach node 2 before node 3, and so on.
• Your path must fill every cell in the grid — no gaps allowed.
• Reach the final node last to complete the puzzle.

↩ Backtracking

Click any cell already in your path to rewind back to that point and try a different route.

💡 Tips

• Start in a corner — it has only 2 exits, so you won't box yourself in.
• If you're stuck, look for cells with only one unvisited neighbour — they must be visited next.
• Work backwards from the final node when stuck near the end.
