The rules fit on an ice cube
Four simple rules. Endless ways to think them through.
One penguin per row
Every row gets exactly one penguin. Once a row has its penguin, the rest of that row is empty ice.
Footprints mark the rest of the rowOne penguin per column
The same goes for columns. Each column holds exactly one penguin, top to bottom.
One per columnOne penguin per color
Each colored ice floe needs exactly one penguin. Two penguins on the same floe is a no go.
Two on the purple floeNo huddling
Penguins never touch each other. Not side by side, not above or below and not even diagonally at the corners.
Touching at the cornerSolved!
When every row, column and color has its penguin and nobody is touching, the colony cheers and the board is complete.
Tap, tap, waddle
Tap once
Leave a footprint to mark a cell where a penguin can’t go.
Tap twice
Place a penguin. Tap a third time to clear the cell.
Drag
Drag across the board to leave a trail of footprints in one go.
Think like a penguin
Start with small floes
A color with only one or two cells has very few choices. Solve those first.
Watch for lined up floes
If a whole color sits inside one row, that row’s penguin must be on that color. Mark the rest of the row.
Ring every penguin
When you place a penguin, add footprints on all eight cells around it. Nobody else can stand there.
Never guess
Every Waddzle board has exactly one solution and can be solved with logic alone.
