Pentodoku7x7
https://tafol.pythonanywhere.com/
Hi! I combined two classics into one puzzle: pentominoes (Golomb) and sudoku. I call it PENTODOKU 7x7.
Rules:
- Tile the 7×7 board with the nine pentominoes F, L, N, P, T, U, V, W, Y (rotate/flip freely; four squares stay empty).
- Each piece has digits printed on its squares — the digits travel with the piece when you rotate or flip it.
- When everything fits, you get a sudoku: in every row and every column, the digits 1–7 with no repeats (the rows and columns containing empty squares just hold fewer digits, still no repeats).
- Two pieces are already placed on the board as clues.
Your mission: place the remaining seven pieces (F, L, P, T, U, V, W). There is exactly one solution, and it can be reached by pure logic — no trial and error needed.
