QiYi Magnetic Number Sliding Klotski 4x4

QiYi Magnetic Number Sliding Klotski 4x4 is a number sliding puzzle from QiYi, also known as the 15 puzzle. The 4x4 board has 15 numbered tiles and one empty space. You slide the tiles one at a time into the empty space, and the goal is to arrange them in order from the lowest to the highest number. Unlike basic sliding puzzles, this version has magnets, so the tiles settle into their positions instead of moving loosely around the board.

How to solve it

You can explain the rules in a few seconds, but solving the puzzle takes thinking a few moves ahead. The most popular method is to solve it step by step: first the top row (1-4), then the second row (5-8), and finally the two bottom rows together, column by column. Your first solve will usually take a while. Once you master the pattern, you can start timing yourself and work towards smooth solves without unnecessary moves, just like with a cube.

The magnets help align each tile in its slot, so when you slide faster, the pieces tilt less often and lock up less.

Who is it for?

For a child or an adult who wants to try a puzzle other than the classic 3x3 cube. The numbers and simple rules make this sliding puzzle a great first logic puzzle. Cubers often use it as a break from cubes. It's a good non-WCA puzzle that you can solve against the clock. It's flat and light, so it easily fits in a backpack.
