Capydoku

Soak your mind in the warm hot-spring sanctuary of Capydoku! Place exactly one charming capybara in every colored region, row, and column without any two capybaras touching—even diagonally. Single-tap or drag across cells to mark X exclusions, double-tap to place a capybara, use explanatory deduction hints that teach the exact rule and R#C# coordinate, customize your capybara's spa hat and board atmosphere, and solve 20 uniquely solvable boards from 4×4 to 10×10.

Single-tap or drag/swipe across cells to mark or clear X exclusions. Double-tap an open cell to place a Capybara. Keyboard/Gamepad: Arrow keys or D-Pad to move focus, Space/X or X button to mark/clear X, Enter/C or A button to place a Capybara.
