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. |

Country : India | Vishal posted @ 2016-02-20 2:53 PM Thanks David for your help and guiding me through the solving technique.. 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! |

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. |

Thanks for the great set of puzzles David. The solving path was seamless in the puzzles I attempted. Personally, back to solving puzzles after a brief period of 2-3 months and it was a great experience for me attempting the puzzles. Hope to be active in the upcoming contests. |
