Ducks in a Row — Logic Puzzle

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.

A hand-tuned campaign from friendly 6×6 warm-ups to colossal 10×10 brain-benders, with sizes and difficulties shuffled so every level feels fresh. Beat the clock, earn time extensions, and climb through ten chapters.
