One animal per row, column and pen, never touching. Cosy logic puzzles from 4×4 to 10×10, a daily streak and a leaderboard. No sign-up.
Barndoku is a logic puzzle with the rules of sudoku and the charm of a farm.
Every board is a grid of coloured pens. Place exactly one animal in each row, each column and each pen, and never let two animals touch, not even at the corners. That's the whole rulebook. The thinking is in working out where an animal can't go, fencing off those cells, and watching the last possible spot reveal itself.
If you enjoy star battle, sudoku or any one-per-row logic puzzle, you'll feel at home in the barn.
HOW A PUZZLE PLAYS
• Tap a cell to fence it off when you know no animal can live there.
• Double-tap to place an animal when only one spot remains.
• Boards grow from a 4×4 warm-up to 10×10 brain-benders.
• Stuck? A hint points at the next deduction. A reveal shows a cell outright. Both refill every hour.
A LITTLE EVERY DAY
• Daily Streak: solve one puzzle a day, keep the flame alive, earn prizes on day seven.
• Leaderboard: each solve lays eggs. Climb past the other farmers before the day resets.
• Daily Challenge: one big board shared by everyone, with your finishing time ranked against the crowd.
MAKE IT YOURS
• Every animal you reveal for the first time unlocks it as your face, with its own frame.
• Pick a handle, wear your favourite face, and see your name on the board.
MADE FOR GROWN-UPS WHO LIKE A THINK
No timers on the ladder, no lives, no penalties for taking your time. Pattern Mode swaps the colours for patterns if that reads better for you.
No sign-up. Your progress is saved automatically and you can delete it from Settings at any time.
