Slide the tiles into the correct order. Deceptively tricky — brilliantly satisfying.
The Sliding Puzzle (also known as the 15-puzzle) challenges you to restore a scrambled image by sliding tiles one at a time into the empty space. It's one of the most elegant logic puzzles ever created — the rules take 5 seconds to learn but mastery takes much longer.

Work row by row from top to bottom. Always place the top-left tiles first. Never try to place two tiles in the same row at the same time — they'll block each other.
It requires planning multiple moves ahead, spatial thinking, and the ability to break a complex problem into smaller steps — all valuable cognitive skills.
The 3×3 version is accessible from age 6. The 4×4 suits ages 10+ and the 5×5 is a genuine challenge for adults.
