About Tile Slide

The sliding puzzle your grandparents carried in a coat pocket, now four taps away. Numbers one to fifteen start scrambled and you nudge them back into order through the single empty square. Every shuffle is solvable — we check the parity before the board is handed to you, so no arrangement is a dead end.

How to play

• Tiles can only move into the empty square, one at a time.
• Put 1 to 15 back in reading order, left to right, top to bottom.
• The move counter and timer both run from your first move, not from load.

Tips from the people who built it

• Solve the top row first and then leave it alone. Working row by row stops you undoing finished work.
• The last two rows are the hard part. Get the bottom-left corner right before you touch the final pair.
• Stuck in a loop? Press Shuffle. A fresh board is faster than fighting a bad one.
