This is a classical puzzle that works on the number 13 and japanese sums. The very beginning is easy, but I think that the final level is a little ***. You’ll see…
Japanese sums : The clues outside the grid indicate the sums of the contiguous regions found in that row or column that must be shaded. There must be at least an unshaded cell between regions. The number in the clue indicates the sum of the digits in each region.
Killer cages : Digits in cages must sum to the number given at the top left corner of the cage. Digits may not repeat within a cage.
The blue lines work as cages : they sum 13, and digits may not repeat.
Little Killer : Clues outside the grid, with a little arrow, give the sum of the digits along the indicated diagonal.
Digits can repeat if allowed by other rules
