Normal sudoku rules apply. Diagonals and cages are NOT standard. Digits MAY repeat in cages and along indicated diagonals. The numbers should be read as a "look-and-say number". Each number says which digits are in the respective cage or on the respective diagonal. For example, if a cage clue is 1221, this means there is 1 two and 2 ones in the cage. If a diagonal says 33, then there are 3 threes along the diagonal.
