How to Play

The objective is to move tiles one by one until the numbers are in order from 1 to 15, with the empty space at the bottom right. Each move should be considered carefully, as a single slide can change the entire puzzle. The game begins with a random shuffle, so every playthrough is unique.

Regular play helps improve spatial reasoning and problem-solving speed. Take breaks if stuck, as a fresh perspective often reveals new solutions.
