Thanks for playing Pingdoku! If you have a question, a bug to report or a suggestion, we would love to hear from you. Most emails are answered within a few business days.
When reporting a problem, it helps to include:
Place exactly one penguin in each colored region. There can be only one penguin per row and one per column, and penguins can’t touch each other, not even diagonally. Tap once to mark a cell with a cross, tap twice to place a penguin. Level 1 walks you through it step by step.
A penguin placed on a cell where the solution has no penguin costs a heart. You have three per grid. If you run out, simply start the grid again — nothing else is lost.
No. Every grid has exactly one solution, checked by a solver before it ships, and it can always be found by logic alone. When you are stuck, look for a color, a row or a column with very few free cells left — that is usually where the next penguin hides.
It gives you a hint. It first points out a cross placed where a penguin belongs, then crosses you forgot around a penguin you already placed, and only then reveals a new penguin.
Once you reach level 20, a new puzzle is waiting for you every day. Solve every puzzle of a month to win its trophy. Everybody gets the same puzzle on the same day.
Each one has a switch in Settings, behind the gear icon.
