About Klotski
Klotski is the classic sliding-block escape puzzle. A small board is packed with blocks of different sizes, and one of them is a big 2×2 square that has to reach the exit at the bottom centre. Blocks never rotate and never overlap; they only slide into the empty space beside them, one move at a time. Because the board is so tightly packed, freeing the big block means patiently shuffling the smaller pieces around it to open a route down. The famous opening layout takes over a hundred moves to crack. No signup, no download.
Frequently asked questions
Drag a block into the empty space beside it. Blocks slide horizontally or vertically only - they never turn and never overlap - so you rearrange the smaller pieces to make room for the big block to move.
You win when the large 2×2 block reaches the exit at the bottom centre of the board. Everything else on the board is just in the way of getting it there.
A block can only move into adjacent empty cells, and only as a whole. If the space next to it is occupied or off the board, it is stuck until you clear that space first. Blocks cannot rotate.
There are several hand-made levels of rising difficulty, and solving one advances you to the next. The difficulty setting picks where you start - Easy on a quick board, Hard on the classic layout that needs over a hundred moves.
