Daily Kaodoku

Hey, have you heard of Kaodoku puzzles? It's like Sudoku, but with smileys instead of numbers! There are 4 different difficulty levels, so you can challenge yourself. The goal is to fill in the grid with the right smiley faces - each one has 3 possible mouths and 3 possible shapes, so there's a total of 9 different combinations. Just like in Sudoku, you can't have the same smiley face in any row, column, or 3x3 box. Sounds fun, right? Give it a try and see if you can master this puzzle game!
