Klotski is the ninth game on IOTL Games — the sliding-block puzzle known in Chinese as Huarong Pass (Hua Rong Dao), in France as L'Ane Rouge (the Red Donkey, 1932), and in Japan as Hakoiri Musume (Daughter in a Box, 1933). The legend dates to the Battle of Red Cliffs (208 CE): warlord Cao Cao fled north through Huarong Pass; the loyal general Guan Yu let him escape to repay an old debt. v1 ships 18 hand-tuned stages across 5 tiers (Initiation to Master) culminating in the canonical Heng Dao Li Ma, proven by computer in 1964 to require 81 finger-moves minimum. BFS-verified optimum per level, 3-star scoring, optimum hidden until first solve, Daily Challenge + Endless mode, Three Kingdoms narrative wrapper, bilingual piece bios.
