27x27 Alphabetic Sudoku

This isn't the sudoku you grew up with. Instead of numbers 1-9, this monster grid uses the full alphabet, plus one, spread across a massive 27x27 board. Same core logic you already know, scaled up to a completely different level of challenge.

If the 9x9 puzzle was where you learned the rules, this is where you put them to the test.

What's inside:

• One original 27x27 alphabet sudoku, hand-designed from scratch

• Full answer key included

Made for: puzzle lovers, sudoku regulars, and anyone who wants to know if they can go the distance, no shortcuts, no easy wins, just letters, logic, and patience.
