This is a puzzle to help beginners understand triangular numbers.
Normal sudoku rules apply.
In cages, digits sum to the number in the top left corner of the cage. Digits may not repeat in a cage.
Solution code: Row 9 (left to right) and Column 4 (top to bottom).

Well it says my solution code is wrong. CTC link, likes my solution and I can't spot any error.....Now I have found it. I read the 11 cage was a 13 cage (box 1) haha joke on me. I'll do it again one day. But really enjoyed it and possibly made a great deal harder with misreading the cage total. I imagine there is another mistake somewhere as well.

Very nice, enjoyable puzzle. I'll attempt to get my wife to try this one, as she is a beginner and new to killer sudoku.

Great break in with usage of triangular numbers. Smooth yet not immediate solve with killer logic after break in
