Pengwin GO! is a sudoku-style logic puzzle with three rules. Here they are first: - one penguin per color - one penguin per row, and one per column - no two penguins next to each other — corners included That's all of it. The rest you work out yourself. The board comes already divided into color patches. Seat your penguins until all three rules hold. When a square can't work, tap it and leave a mark. Every answer you rule out narrows what's left, and each board has exactly one solution. TWO PENGUINS, ONE BEACH The first is the original penguin: round, unhurried, unbothered by what anyone thinks, doing his own small stubborn thing. The second is the elegant penguin, in detective styling — hat, magnifying glass, certain the clue is always in the grid. Ice and sand both suit them. They play Pengwin GO! either way. Grids start at 4x4 and go up to 12x12. A fresh board lands every night at midnight — play it or don't. Stuck? A hint nudges without giving the answer. Airplane mode works: tunnels, flights, basements. Nothing interrupts a board in progress. Free. No account. One hand. The first board explains itself in about ten seconds.
