Six chapters of new rules, 46 levels: mud, sleepers, a lost lamb, falling bridges, one-way paths, gates, an autumn wind, heavy and hopping animals, ice, a mirror animal, and a wolf in the fog that steps toward whoever is nearest. The herd grows from two animals to four, and these boards run from 7 moves to 22. Daily Herd, Endless and Reverse. Challenge a friend with a code and race their moves. Build your own levels and let the solver check them. Pip, Bo, Moss and Zuzu now breathe, lean and land — each one moves to its own rhythm instead of sliding. A coach after each board shows you which move cost you. The first 15 classic levels and the whole Spring chapter are free.
