Does this help? |

Re: Max/Min Triplet Sums
I'm not very good at walkthroughs.
Try the following. Place two missing 8s by standard logic. Place 2s in boxes 6 and 7 by standard logic. Place 3 in box 8 by standard logic. Place 1 in box 3 by standard logic.
Now in row 4, the missing 1 cannot sit either side of the 3 and 2 (otherwise we would have a 6 sum in that row and we are told that 10 is the minimum sum) so it must go in column 2.
In the same row, the missing 5 must be either side of the 3 and 2 (otherwise we can't have a 10 sum). Therefore, column 3 in that row must have a 6.
In column 5, the 8 sum must be 1-3-4 in some order as the 2 is isolated. The 1 can't lie below the 3 as there would then be a 6 sum. So the 1 must go in row 5 and the 4 in row 6.
In box 4, the missing 3 can't go in bottom right corner as there would then be a 9 sum in row 6. So it goes immediately above that with the missing 4 to its left.
Then look at the 8 sum in column 3. etc.

Re: Arrowhead
Consider the diagonally split cell in top right corner of box 5. The arrow cannot point to the south-east as the first digit in that direction is a 9 and the sum of the first two digits will therefore exceed the allowed value. So, the arrow must point to the north-west and the first two digits in this direction are 3 and 4, adding to 7. The top left triangle in our split cell is coloured black and a 7 is placed in the bottom right triangle.
Hope this gets you going. |

This was a good test : ) would have given it 3-stars if online solving was available - I don't have a printer so for puzzles without online solving I have to write all my answers in MSPaint with my mouse, which makes it take quite a bit longer and makes it difficult to write pencil marks. |

By the way, I failed to understand the rule - it was for all the combinations of consecutive numbers along a row and column; not only for the first 3...Thanks for your explanation.. |

I really liked this test.Normally,I hate Math based variants in sudoku but this test was different.I remember thinking before the test that I would be happy with a score somewhere around 400.I didn't expect 470 in 90 mins (74?! ).In the last 16 mins of the test,I really had a go at Thropki (100 ) but it seemed beyond my reach despite multiple guesses. I greatly enjoyed solving Outside and Triangular sums both of which had a very systematic solve and I also loved the squeeze variants. Thanks a lot to David for this wonderful test and to all test solvers. The set was delightful and I had great fun! |

![20](https://logicmastersindia.com//forum/images/decorations/multiple/25.gif) Country : Turkey | bskbri posted @ 2016-02-20 8:14 PM I have two questions on triangular sums:
1. Are we sure that we won't split any more cells? I am confused because the rule says triangles cannot touch grid boundary. These already placed ones are far enough not to touch :)
2. May the three numbers around a triangle be same? |

Re: Triangular Sums
All split cells will be indicated before solving.
There is no special rule prohibiting more than one edge of a triangle having the same digit. |
