Originally this puzzle was meant to have no letters, which I pursued as a personal challenge. But I decided the resulting puzzle wasn't actually fun, and so I've set this with that goal in mind instead. I hope you enjoy.

Rules:

Tapa: Shade some cells to form a single connected wall. Cells with clues cannot be shaded, and shaded cells cannot form a 2×2 square anywhere in the grid. Every shaded cell must contain a digit from 1-9, which may not repeat within any row or column. Unshaded cells are completely empty except for given clues.

Hungarian Tapa: Numbers in a cell indicate the sums of unbroken strings of shaded cells in the 3x3 area around that cell, in no particular order. If there is more than one number in a cell, then there must be at least one unshaded cell that separates/breaks up each such string. Digits may repeat within a string. Every clued cell is fully clued, and does not have any extraneous strings surrounding it.

Question Marks: A ? represents a single digit number. A ?? represents a double digit number, which may not begin with 0, but may end in 0.

Cipher: Each letter must be replaced with a unique digit from 1-9.


I've made an example for people to solve if they'd like, with the digits 1-6 and only two cipher digits. It should also demonstrate the rules in action, and I actually think it's pretty cool in the world of example puzzles.
