About RubberDucku!
Find a home for every rubber duck. One per row, column and color — with a little space between neighbors.
RubberDucku! is a cozy logic puzzle with little yellow rubber ducks. Each row, column and colored region needs exactly one duck, and ducks cannot touch, even at the corners.
Start with a guided practice board, then work through 100 puzzles from small 4 × 4 grids to thoughtful 8 × 8 challenges. Tap to cross out a square, double-tap to place a duck, or switch to Duck mode for single-tap placement.
Every puzzle has one solution. Use logical hints when you need a nudge, undo a move or swipe across several squares. Your best stars, times and settings save automatically; returning opens a fresh board at your current level.
