Xmas 2020 Sudoku

Swap your usual Sudoku grid for a festive one that’s trickier than it looks — can you fill every row, column, and 3x3 box before the eggnog kicks in?

I’ll be honest: the Christmas theme is just window dressing. The real meat here is the puzzle, and it’s a solid one. Classic Sudoku rules apply — fill the 9x9 grid so every row, column, and 3x3 box contains the numbers 1 through 9 exactly once. The holiday twist? The numbers sit inside little ornaments or candy canes depending on the screen, and the background is all deep reds and snowy whites. It’s cozy without being too distracting. What got me hooked was how clean the input feels. Click a cell, pick a number from the bottom, and it locks in instantly. No lag, no fuss. I legitimately lost track of time one evening and finished the whole puzzle in a single sitting. Halfway through, I hit that classic Sudoku panic: a near-full grid with two numbers left and no legal moves. Then I spotted the 7 I’d placed three rows up. That facepalm moment is pure Sudoku, and this version nails it. If you’re new to number grids, don’t sweat it. The clue system is gentle — you can jot down multiple candidates in a cell to narrow things down. And since it’s unblocked in your browser, you can sneak a round in between classes or meetings. No download, no sign-up. Just you versus the grid, with some tinsel thrown on top.

Start with rows or boxes that already have six or more numbers filled — those are your easiest wins. Use the candidate notes (small numbers) to eliminate options in crowded boxes. Don’t guess. If you’re stuck, check a different row or column; a single missed number can unlock the whole grid. The festive theme won’t help you solve faster, but turning the sound off can if the jingles get repetitive. Work on the middle box early — it shares the most rows and columns with other regions.
