Pell Puzzles

Pell Puzzles are logic path puzzles where your goal is to fill the 6×6 grid with exactly eight paths, each with a different length.

Every puzzle includes X and O markers placed around the grid. Your task is to connect them with paths that follow strict rules.

The golden rule:
Each path must have a unique length from 1 through 8.

How paths work:

• Paths of length 2 through 8 connect one X to one O.
• The length-1 path is simply marking a single X.
• Paths move through the grid one cell at a time.

There are also a few constraints to keep the puzzle fair:

• Paths cannot touch themselves (diagonals are allowed).
• You cannot form a 2×2 block of filled path cells.
• Every required path length must appear exactly once.

Why we like it:

• ✅A clever mix of path drawing and logic deduction.
• ✅The unique path lengths add a satisfying twist.
• ✅Each puzzle feels like solving a tiny maze system.

Hint: Start by placing the longest paths first. They usually have far fewer possible routes.
