What kind of beast Fifteen Puzzle Online is: rules, tricks and a few tips

The igrasu.ru catalog holds hundreds of games, and this is one people keep coming back to. Here is how it works and how to get the most out of it.

What this game is

The classic 15 Puzzle: arrange a 4×4 square by putting the tiles in order from 1 to 15, with the empty cell in the bottom-right corner. A tile moves only into the neighbouring empty cell. Fewer moves is better.

Controls

Controls: click (or tap) a tile next to the empty cell to slide it. Arrow keys and WASD also work. The "New" button shuffles and restarts. Sound can be muted with the button on the game page, and "Demo" starts an auto-play mode that shuffles and moves by itself.

A few final tips

• Check out the demo mode on the game page — the AI shows how it is played, and repeating it yourself gets much easier.
• Play in short sessions: the best results come with a warmed-up head.

Take note: it works great solo and in a "my high score is bigger" company. Ready to try? "Fifteen Puzzle Online"
