How to Play Number Puzzle

Objective: Arrange all numbers from 1 to 15 in order, with the empty space at the bottom right.

Winning: Complete the puzzle with numbers 1-15 in order and the empty space at position 16.

Strategy & Tips

Start with Corners: Focus on getting the first row and first column in place first. This creates a foundation for solving the rest.
Work Row by Row: Complete rows from top to bottom, then columns from left to right. This systematic approach helps avoid getting stuck.
Plan Ahead: Before moving a number, think about where it needs to go and how to get the empty space to the right position.
