Summer 2024 🏖️

The Krazydad Discord Community is a new place where you can talk to me, and meet other people who are interested in puzzles. A great place to report problems or mistakes with this website, suggest new features, help me brainstorm and test out new puzzles, get periodic announcements from me, or discuss other deep thoughts. Maybe I'll see you there!

Krypto Inky Puzzles

Krypto Inkies (a Krazydad original puzzle) are regular Inky (or Calcudoku) puzzles that have been encrypted. Each digit has been substituted with a letter. To solve the puzzle, you must deduce what digit each letter stands for, while working out the solution to the decrypted puzzle.

These puzzles are intended for solvers who are already pretty good at solving regular Inky or Calcudoku puzzles, so if you haven't solved any of those, I suggest you solve a few regular Inky puzzles first.

My Krypto Inky puzzles are available in four sizes (5x5, 6x6, 7x7, and 8x8). Each volume contains 100 printable booklets. Within each volume, the books are ordered by ascending difficulty -- so Book 1 contains the easiest puzzles (which are still quite challenging, you'll find) and Book 100 contains insanely difficult puzzles. Each booklet contains eight puzzles and a page of answers.
