Puzzle Guide

Puzzle Objective

The aim of the game is to arrange the numbered tiles in ascending order, from 1 to 15, with the empty slot (referred to as the free space) ending up in the bottom-right corner. The final layout should look like this: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 _

How To Play

The game begins with the tiles shuffled randomly across the grid. The empty slot (_) is used to move tiles around.

Controls: Click to move a tile into the empty slot.

Tile Movement Rules: Only tiles adjacent to the empty slot can be moved. Tiles slide one space at a time into the empty slot. You cannot move diagonal tiles.

Winning Condition: The game is complete when the tiles are arranged in ascending order, as shown in the Objective section. The empty slot must also be in the bottom-right corner.

Strategies for Success

1. Solve Row by Row

Focus on placing the first row (1, 2, 3, 4) in order first. Then, work on the second row, ensuring the first row stays intact. Repeat for the third and fourth rows.

2. Master Corner Tiles

Corner tiles (e.g., 1, 4, 13, 15) can be tricky to position. Prioritize placing them early to simplify the puzzle.

3. Learn The 3x2 Method

After arranging most tiles, focus on solving the last 2 rows or the final 3x2 grid section using a systematic approach. Keep experimenting with movements to align the numbers.

4. Plan Your Moves

Avoid random movements, which can jumble the tiles further. Visualize where each tile needs to go and plan accordingly.
