How to Play
This game is played exactly like the original Sudoku puzzles, but in place of numbers there are letters (EX: 1 = A, 2 = B, 3 = C, etc.)
To put together your worksheet, first copy and paste one or more of the 18 pre-made puzzles onto the worksheet slide (first slide).
Then, if playing with words or sentences instead of letters, replace the letters accordingly (EX: A = Word/Sentence 1, B = Word/Sentence 2, C = Word/Sentence 3, etc.)
Finally, resize and adjust the puzzles on your worksheet as you see fit and print!
Letters work great for practicing phonics, but you can also use vocabulary words or target sentences in place of the letters.
If using as an online teaching activity, save your worksheet as a jpeg or pdf and convert it to an interactive/live worksheet that students can do on their computer. Feel free to use the website or program of your choosing to do this. One website I found out about recently is
Or, if using for Zoom classes and students don’t have a copy of the worksheet beforehand, you can put your puzzle on a PowerPoint slide and have students redraw it in their notebooks. Though, I only recommend this for the 4x4 or 6x6 puzzles as the 9x9 puzzle may take too much time.
