- Normal Sudoku rules apply.
- Green lines are German Whisper lines. Adjacent digits along a GW line must differ by at least 5.
- A purple Renban line contains consecutive digits in any order.
- Gray lines are palindromes. Digits along a palindrome read the same forwards and backwards.
- Outside clues are Numbered Rooms clues. The digit closest to the clue gives the position in the row/column of the digit matching the clue, counting from the clue's side of the grid.
- The two ? Numbered Rooms clues have the same value that must be deduced.
