LINE UP YOUR DUCKS. USE YOUR BRAIN. 🦆
Ducks in a Row is a calm, clever placement puzzle: put exactly one duck in every row, every column and every coloured pond — but ducks are territorial, so no two can ever touch, not even diagonally. Simple rules, deep deductions.
If you love queens-style placement puzzles, Star Battle or sudoku, you’ll feel right at home.
🧠 PURE LOGIC, ZERO GUESSING
Every single puzzle is machine-verified to have exactly one solution that can be reached by pure deduction. If you’re stuck, there’s always a logical next step — you never have to guess.
