Sudoku Christmas

Holiday icons fill the grid in Sudoku Christmas. Christmas trees, candy, candles, houses, and other seasonal symbols replace the usual digits, yet each icon still carries a number marker for Sudoku logic. Three board sizes are available: 4x4, 6x6, and 9x9. Four difficulty settings appear on every board. More symbols placed in the grid at the beginning lower the difficulty. Fewer preset spaces make the puzzle harder. Most layouts already contain many filled cells, which makes this puzzle game easier than many standard Sudoku versions.

How to play?

Choose a board size, then pick one of the four difficulty options tied to how many cells are already filled. Filling empty squares with the right holiday icons completes the puzzle under classic Sudoku rules. Rows must avoid duplicates. Columns follow the same rule. Each marked section also needs a different symbol in every cell. Number labels on the icons help track their Sudoku value while placing the matching Christmas item into the correct spot.
