Number Maze is a logic path-finding puzzle. You are given a grid with some pre-filled numbers. Your task is to find the unique Hamiltonian path ā a route that visits every cell exactly once, stepping only to adjacent cells (up, down, left, right), with numbers placed in ascending order from 0 to NĀ²ā1.
rules
The path starts at 0 and ends at the highest number (NĀ²ā1).
Each step must move to an adjacent cell (up, down, left, or right ā no diagonals).
Every cell must be visited exactly once.
Pre-filled numbers (shown in blue) cannot be moved and must appear at their correct positions in the path.
Each puzzle has exactly one valid solution.
controls
Click an adjacent empty cell to place the next number.
Click a placed number to undo back to that point.
Press Check to verify your current path.
Press Hint to reveal the next correct cell.
Press New Game to generate a fresh puzzle.
Toggle Sound with the speaker button.
scoring
Your performance is measured by the number of moves and the time taken to complete the puzzle. Fewer moves and faster completion indicate better solving skills. The move counter tracks every cell placement, including any undos and re-placements.
tips
Start by studying the pre-filled numbers ā they constrain where the path must go.
Look for bottlenecks: cells with only one possible neighbor in the sequence.
Work from both ends (0 and the final number) toward the middle.
If you get stuck, use Hint to reveal one correct cell without penalty.
Undo freely by clicking any previously placed number ā experiment to find the right path.
faq
What is a Hamiltonian path?
A Hamiltonian path visits every cell in a grid exactly once, moving only to adjacent cells. In Number Maze, you number each cell from 0 upward, creating this path.
Can I skip cells or move diagonally?
No. Each step must go to a directly adjacent cell (up, down, left, or right). Diagonal moves are not allowed, and you cannot skip over cells.
How are the difficulty levels different?
Easy uses a 5Ć5 grid with many pre-filled clues. Medium uses 6Ć6 with fewer clues. Hard uses 7Ć7 with minimal clues, requiring more logical deduction.
