Klotski (横刀立马) is a classic Chinese sliding block puzzle. The goal is to slide the large 2×2 block (曹操) to the exit at the bottom center.
Use arrow keys or swipe to slide blocks. Blocks can only slide — they cannot jump over other blocks.
The gold block is 曹操 (Cao Cao). The jade blocks are his generals. The cyan blocks are soldiers.
Your score is your move count — fewer moves is better!
