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.
