Klotski

Master the classic Hua Rong Dao puzzle in a beautifully tactile 3D environment. Can you guide the Red Block to freedom?

Klotski 3D is a modern, polished take on the centuries-old sliding-block brain teaser (also known as Hua Rong Dao, Huarong Path, or Pennant Puzzle). Trapped inside a wooden tray, the large Red Block must reach the exit at the bottom. The catch? You can only slide the surrounding pieces horizontally or vertically into empty spaces to clear a path.

It sounds simple, but freeing the red block requires deep logic, strategy, and spatial awareness!
