Think. Plan.
Place. Moo!

Simple rules. Satisfying deductions.

Every puzzle has a logical path from its starting cow to the final square—no blind guessing required.

🐄

Place the herd

Put one cow in every row, every column and every coloured paddock.

❌

Give them space

Cows cannot touch horizontally, vertically or diagonally. Mark impossible squares as you reason.

⭐

Protect your stars

Begin with three stars. A wrong placement costs one, so careful deductions earn the perfect result.

Out in the pasture

Bright farmyard presentation, clear boards and quick touch controls designed for portrait play.

One cow. One clue.

Then the logic takes over.

Rule out crowded rows, columns and paddocks until only one safe home remains. Each answer opens the way to the next.
