CatDoku

Description
Solve cat-themed logic grids by finding positions that satisfy three rules at once. Every row, column and colored region needs one cat, and cats must never touch, including at corners. Larger and more restrictive boards make deduction harder as you progress, with hints available when a placement remains unclear.
How to play
Tap an empty cell to place a cat and tap again to remove it. Keep one per row, column and region, with no neighboring cats.
