Pengwin GO!

Pengwin GO! is a Sudoku-style logic puzzle where you place penguins on color-divided grids. Follow three rules: one penguin per color, row, and column, with no penguins touching—even diagonally. Mark impossible squares to narrow down each board, which has exactly one solution.

Play grids from 4×4 to 12×12, get a fresh board every night, and use hints when you’re stuck. The game works offline, needs no account, and is free to play.
